WHAT IS CADENCE SENSOR When making the choice between the cadence sensor and the torque sensor, answer this question first: Are you looking for an E-bike that can do the most work for you? If YES, an E-bike with a cadence sensor might be the best choice. Cadence-based pedal assist systems will let the electric bike’s motor work (While the PAS is on) when a rider begins to pedal. Simply, when the cadence sensor detects the rotation from the pedals(Mostly a quarter turn and adjustable), the cadence sensor will send a signal to the controller, then the controller tells the motor to start work, then the motor will work as the controller told it, start smoothly or full power start(Set in controller). The effort a rider puts in and the selected PAS level will effect how many power the motor outputs. For example, on a cadence-based E-bike, manufacturers generally have preset speeds for each level of PAS. As your pedal cadence increases, the motor will continue to output until it reaches its MAX preset speed or power. While in flat terrains, the E-bike may reach the MAX preset speed, but when in steep terrains, the E-bike could not reaches the preset MAX speed even the motor work on its full power. • As the chainwheel's rotation comes to the MIN needs of the cadence sensor, the PAS will told the controller to let the motor engage. Your E-bike may need to move a longer(Compared with torque sensor based E-bike) distance before the motor could engage. This will be a significant difference when you are ride off road or on a steep terrain. • As the pedaling speed increases, the PAS will increase the motor’s output power/speed to the preset (NOT your pedal cadence). • As the pedaling speed decreases, the PAS will decrease the motor’s output power/speed to the preset (NOT your pedal cadence).   ADVANTAGES OF CADENCE SENSOR ELECTRIC BIKE A electric bike cadence sensor is used to detect how fast the a rider is pedaling, the faster you pedal the chainwheel, the more the motor helps you, there are some benefits that comes. Ease To Use One of the biggest advantages of riding an E-bike equipped with a cadence sensor is its very ease to use. Cadence sensor-based electric bikes require light pressure on the pedals to activate the motor, or we could say, when the cadence sensor noticed that the chainwheel's rotation is enough, the motor will engage and provide massive assistance. Efforts Saving After the motor engage(Before the motor start, you need to pedal the e-bike on your own), you can put MIN efforts which is enough to rotate the pedal and the motor will keep engaging. This makes cadence-based electric bikes becomes a better option for those recreational riders or someone with physical limitations but still wants to ride. Leisurely Cycling You can choose if they want to cruise around and have a leisurely ride, pedaling at low assist levels for less assistance. Or, you can turn the PAS level higher to feel the wind. Whatever you want, the electric bike will gives you.   Looking for folding E-bikes? Click here   DISADVANTAGES OF CADENCE SENSORS ELECTRIC BIKE Though the cadence-based electric bikes are suitable for all riders of all ages, sometimes riders want the riding feel more likely as ride a normal bike, like every time they pedal, they feel like they are pedaling the bike. The cadence sensors could not apply it.   Less Workout If you want an E-bike to feel more like a normal bike, the cadence based E-bike may not the best choice (If you turn off the PAS, it will be a normal bike). The cadence based E-bike will let the motor engaged anytime when the sensor sensed any rotation. You couldn’t feel an intense workout when riding an E-bike based on cadence sensors, the E-bike will do the most of work for you and you will feel relaxed and enjoy the view, but this may be an absolute riding experience that requires less effort!   Less Mileage(Mostly) Mileage is one of the important factors when purchasing an electric bike. There are a lot of factors will effect the E-bike's mileage. Extensive use of cadence-based PAS, especially at higher levels for a long time(Such as PAS 4 of 5), needs a large amount of electricity to power the motor. The battery's capacity is certain, decide how many mileages on a single charge. The cadence sensor will let the motor engage (Before exceeding the MAX speed) the time it feels rotation from your pedal, such as when you are down hill, even if you are empty pedaling (You are not using any effort), the cadence sensor will also let the motor engage all the way to exceeding the MAX PAS speed, but you don't need any help from the motor in this situation.

A torque sensor measures how much force you are applying to the pedals, then calculates how much power the motor should be. A torque sensor will sense your efforts and amplifying your efforts.   • Even if you are static, the time you put efforts on your pedal, the torqur sensor will 'know' you needs help, then the motor will engage. You just need to let the E-bike moving a little distance before the motor could engage.It's much easier when ride off road or on steep terrains. • The harder you pedal, the more your motor output, up to the preset of PAS level(Match you cadence). • The less you pedal, the less output your motor will be(Match you cadence).   ADVANTAGES OF TORQUE SENSOR ELECTRIC BIKE The torque-based E-bike has a natural ride feel and more mileage on all types of E-bikes, including a folding E-bike with a torque sensor. More Exercise If your goal is to find an electric bike which feel like a boost on you leg while riding, you come to the right place, choose the torque based E-bike! The PAS naturally works with you rather than doing a most of the work for you, the torque sensor could 'feel' how hard you are pedaling, the harder you pedal, the more the motor boost. Natural Riding Style You may feel more intuitive because the torque sensor is able to adjust the motor’s assistance power to match your pedaling cadence/efforts. You won’t get a sudden jolt of power when changing PAS levels or start to pedal, the torque sensor 'knows' when and how much power the bike should give you and does smoothly and dynamically. It doesn't like the cadence sensor which could only output the preset power of every PAS level. More Mileage Since torque-based E-bikes do not produce a preset output at any PAS level, you may be able to save electricity and ride farther. As torque sensor E-bikes simply assist you while riding, depending on how much effort you’re putting in, torque sensor E-bikes won’t consume extra energy while you don't need assistance, such as when you are down hill, even if you are empty pedaling (You are not using any effort), the torque sensor will not let the motor engage because you don't really need help. Very smart, isn't? Ultimately, giving you more control over your ride, your E-bike, and your experience.   Need torque-based E-bike? Don't miss this one: Model 5    DISADVANTAGES OF TORQUE SENSOR ELECTRIC BIKE Torque sensor E-bike needs you and your motor riding the bike at the same time, so you can't slack off. In order to reach a higher speed, you need to put more effort into pedaling. But a cadence sensor E-bike will immediately output all the way to its highest preset speed. More Effort If a cadence-based E-bike feels too effortless, try a torque-based E-bike. The sensors detect how much effort you’re putting into your ride and help you with the ride, giving you a more natural connection with your E-bike! In addition, once the top speed is reached on an E-bike with a torque sensor, sustaining the top speed will also require your extra pedal power. It's a workout, but sometimes it's a good thing. What if you don't want to pedal but you want to speed up? Um...don't you know a part named 'Throttle'? With this, you could speed up with no pedal! So...this isn't a disadvantage anymore. Note: Class 3 E-bike does not has a throttle  Learn more: Difference between E-bike class 1, 2, and 3   Unable to be lazy As said above, unlikely to the cadence based E-bike, when you ride with a torque based E-bike, you and your motor are riding the bike at the same time. You pedal less, the motor pedals less; you pedal hard, the motor will pedal harder, so you can't slack off, otherwise the motor will slack off with you and the bike will stop.     Sum Up The most important you need to know is, the cadence sensor does not know how hard you are pedaling, it just knowhow fast the pedal you rotate. To explain this, move your bike to a steep terrain, stop it halfway, open the PAS and start pedaling, the cadence sensor E-bike will be harder to start, because your pedal haven't come to rotate enough, the cadence sensor won't be able to know if you are pedaling, so the motor will not engage. But the torque sensor is smarter, it will know when and how much help you needs when you just pedal a little, it could feel the effort you put on the pedal. There is no absolute statement about which is the best between a torque sensor E-bike and a cadence sensor E-bike, but we do have an absolute statement about which one is the best for you depends on the way you ride. Cadence sensor PAS technologies are easy to use, have plenty of power, and give you the freedom to put in as little effort as you want but with big assistance power. Also, E-bikes with torque sensors PAS technologies provide a more natural riding experience. Both types of pedal assist sensors will give you exactly what you want: electricity assistance when riding. The question to ask yourself is, what you want to put in to receive the assistance? If you want feel relaxed and enjoy the view, want to put in as little effort as you want but on high and powerful speeds, try an E-bike with a cadence sensor. Or, if you want natural riding style, more mileage or have some exercise while riding, E-bikes with torque sensors will be the best choice!  

Choosing between e-bike classes 1, 2, and 3 could be a little difficult if you’re not exactly sure what the differences are between each class or what your desired use case is.   Why classify e-bikes 1, 2, and 3 Different countries and regions may have their classifications and regulations for electric bikes, taking into account factors such as maximum speed, power output, and motor activation. Always check your local laws and regulations before purchasing an electric bike.    Find your state's e-bike rules here: https://www.peopleforbikes.org/electric-bikes/state-laws   The classification for electric bikes is not exclusive to the United States, Europe also has its classification for electric bikes, a little different from the United States.   These classifications and regulations aim to provide guidelines for e-bike usage, ensure safety, and determine where e-bikes are allowed to operate.   In our country, electric bikes are classified into Class 1, Class 2, and Class 3 e-bikes, which are defined by the type of pedal assistance and maximum assisted speed. Below are the differences as typically applied in the United States.       What is class 1, 2, and 3   Class 1 e-bikes: Maximum Assisted Speed: 20 mph (32 km/h) Maximum Motor Rated Power: 750 Watts (1 horsepower) Pedal Assistance: Provides motor assistance only when the rider is pedaling(No throttle). Legal Considerations: Class 1 e-bikes are generally allowed in areas where traditional bicycles are permitted, including bike lanes, paths, and trails. Class 2 e-bikes: Maximum Assisted Speed: 20 mph (32 km/h) Maximum Motor Rated Power: 750 Watts (1 horsepower) Throttle: Can be operated directly(without pedaling), using a throttle mounted on the handlebar to activate the motor; Also equipped with Pedal Assist System(PAS) Legal Considerations: Class 2 e-bikes may have varying regulations depending on state and local laws. Some areas allow them on roads, streets, and bike paths, while others restrict their use to roads and streets only. Class 3 e-bikes: Maximum Assisted Speed: 28 mph (45 km/h) Maximum Motor Rated Power: 750 Watts (1 horsepower) Pedal Assistance: Provides motor assistance only when the rider is pedaling(No throttle). Legal Considerations: Class 3 e-bikes are typically subject to more specific regulations and may require additional safety features. They are generally not allowed on bike paths or trails designated for normal bicycles but can be used on roads and streets, following the same rules as normal bicycles.   A detailed explanation of Class 1 e-bikes   Class 1 e-bikes are treated like normal mountain or pavement bicycles in some states, legally allowed to ride where bicycles are permitted, including bike lanes, roads, multi-use trails, and bike-only paths.   Class 1 e-bike definition is having a maximum speed of 20 MPH and is equipped with an electric motor without throttle that only works when the rider is pedaling. Once you start pedaling you will be able to get up to 20 mph (miles per hour), Exceeding this speed, the motor will not work.   Class 1 e-bike riders could ride anywhere(the same as normal bikes) they would due to the low speed and operation. Meaning class 1 electric bikes are allowed on bike lanes, bike paths, and on the road.   A detailed explanation of Class 2 e-bikes   Class 2 e-bikes are often allowed in most places where a traditional bike can go, but some states or cities have add-on restrictions (such as New York City).   Class 2 e-bikes assist when pedaling or by using a throttle and has a maximum speed of 20 mph. The throttle always comes in a grip twist or a button that you hold to make the bike move without pedaling.   All Qualisports e-bikes are class 2 e-bikes, equipped with a throttle; They are 1) Nemo, a very small, exquisite, lightweight e-bike, only 34 lbs; 2) Volador, equipped with Shimano 7-SPEED gears, only 38 lbs; 3) Dolphin, dual-batteries, hydraulic brake USB ports, weight about 51 lbs; 4) Beluga, a 4.25” fat tire e-bike for off-road, sand, and adventurous bike rides.   A class 2 e-bike is capable of riding in most places you ride a normal bike.     A detailed explanation of Class 3 e-bikes   Class 3 e-bikes are generally allowed on roads and on-road bike lanes but can't travel on bike trails.   Class 3 electric bikes just have pedal assist and top off at 28mph. Due to the higher speed of class 3 electric bikes, they’re restricted from certain bike trails and bike paths.   What makes Qualisports’s electric bikes unique is that they are equipped with both pedal assist and throttle. We keep making high-quality and affordable e-bikes that are accessible to everyone, we hope our Qualisports e-bike could delight your life.   To sum up   Class 1: Pedal-assist only; motor assists up to 20 mph. Class 2: Pedal-assist and throttle; motor assists up to 20 mph. Class 3: Pedal assist only; motor assists up to 28 mph.   Learn more at peopleforbikes.org: https://www.peopleforbikes.org/topics/electric-bikes

So, you just buy a new electric bike? Can't wait to go out for a ride? Wait! Do you know what your bike needs? You need more accessories to make it more functional, more safer. Let us introduce the top 8 accessories you should have to be an electric bike rider. NO.8 BIKE LOCK Prices from $2.99 to $300+ on Amazon, you can choose a suitable one by referring to lock test reviews on YouTube. You must have a bike lock because you will ride your loverly electric bike to visit your friends or go to store for some shopping, you have to leave your electric bike outside, so give your electric bike a high-quality lock; they come with various shapes and sizes, such as normal U-lock, chain lock, Disc-lock... personally, I prefer the Disc-lock because the size, very space-saving (BUT your e-bike must have Disc brake). We suggest you never ever leave your electric bike outside by itself being unlocked, Because e-bikes are not cheap, and if lost, that will be very sad. Learn more: Pros And Cons Of Different Bike Lock Types   NO.7 BIKE BELL I'm not joking, it is a really important part, when you ride past other people, you should let them know you are coming to prevent an accident.It always comes from mechanical or electrical, my suggestion is the mechanical one, cheap and enough for use. The good news is all types of Qualisports folding electric bikes are equipped with a bell, no need to buy it extra. NO.6 BIKE ALARM If you often need to leave your e-bike outside for a long time, you should consider buying a bike alarm. The electric bike is not as heavy as a car, if someone wants to steal it, the lock just can slow the thief down; but with the alarm, when it detects movement of your electric bike, it will go off to let other people notice that someone is moving your electric bike. If you want to save some space on your e-bike, you can try some alarms that also have the function of a bell or headlight or any other functions. NO.5 GLOVE While riding, whether you like it or not, you should wear gloves to prevent any damage to your hands while crashdown, nobody wants to crash, but it does happen, so we should prepare for it.There are many types of gloves, generally, we can divide them into full-finger type and half-finger type. Different people prefer different types, choose one you like, but remember, it must comfortable while wearing it, have a good trip.Do you think wearing gloves is just for safety? NO! Many riders may suffer from handlebar palsy, due to long-time compression of a nerve in their wrist, that also lets them feel pain. If it is serious, they may risk suffering from nerve damage too.Learn more: 5 Reasons Why You Should Wear Gloves While Riding   NO.4 PEDAL What? pedals? yes, but what I mean is quick-release pedals or foldable pedals, especially for folding electric bikes! When you fold your electric bikes and carry them, the normal pedals might scratch your car, good news is, our electric bikes are all equipped with foldable pedals. NO.3 PHONE MOUNT Actually, the phone mount was the first accessory I bought for my folding electric bike. I like riding my electric bike for exploring many new places, and I need a map to ensure not lost my way, so I use my phone for directions, I don't want to stop every several minutes to look at my phone to make sure where I am. it's very convenient to look for directions on my phone with a phone mount. BUT, DO NOT operate your phone while riding!   NO.2 FRONT & TAIL LIGHT It's very important to have front and tail lights on your electric bike. They can make you more visible both at daytime and night, let other people or vehicles notice, and also light up your way when at night.Honestly, I hadn't bought lights for my first bike until I got crashed because of a big gap on the road, I can't see the road clearly at night, so I broke my new bike's rim, and my both hands were injured. Yes, not only I didn't have lights, but also I didn't wear gloves... I'm so pitiful...The good news is, now our folding electric bikes are all equipped with lights.   NO.1 HELMET Whether it's legal to ride a normal bike or electric bike in your region without a helmet, we HIGHLY recommend you wear a helmet for your safety. Nowadays, electric bikes are fast, class 1&2 e-bikes can reach 20 MPH, class 3 e-bikes can reach 28 MPH, so an approved helmet is needed.Learn more: What Is Class 1 & 2 & 3 Of Electric Bike?

Increasing the mileage of an electric bike can be a challenge, as the range provided by manufacturers is often based on ideal conditions that are difficult to replicate. However, there are several things you can do to extend your electric bike's range during actual use. By following the tips below, you can improve your electric bike's efficiency and ride farther: Tire pressure Check your tire pressure regularly and maintain it at the recommended level. This can significantly affect your electric bike's mileage, as higher tire pressure leads to lower rolling resistance and better performance. Different tires require different tire pressures, so make sure you know the recommended pressure for your electric bike's tires. If you try to ride with a nearly flat tire, you may find it's very hard and slow, the same to the electric bike motor, it will need more electricity to rotate. so pump up your tire to the suggested pressure marked on the sidewall. For example, our new folding electric bike 'Dolphin Plus', its recommended tire pressure from 35psi/2.4bar/240kpa to MAX. 60psi/4.2bar/420kpa. Tire choice The tire should fit with what you are doing. Many E-bikes have big and wide tires with big anti-slider on them, also called knob tires. Yes, those tires can provide extreme grip when DH(Down Hill), also with bigger rolling resistance, but there is no need for those tires if you just ride on normal roads such as city streets or country roads. Using those big and wide tires on normal roads will dry your battery faster. Some 'fat tire electric bikes' called, tires above 3.0 or 4.0 inches wide, are more suitable for snowfield or sand rides, if you use those fat tires on normal roads, your mileage will decrease(not too much). But there is an advantage of those fat tires, when used on normal roads, they are more comfortable compared with thinner tires(1.5 inches wide or lower), if you come across a step or a hole, the 'fat tire E-bike' can filter through most bumpings, let you feel better, I had felt the difference, that's true. If you just need an electric bike for commuting, we must recommend you a Qualisports Volador which with 20*1.95 inch tire, that's enough for commuting. But if you want riding on beach, we would like introduce the Qualisports Beluga for you, 20*4.25 inch tire, which can ride both on normal roads and beach, have more fun. Lube the chain If your electric bike has a Mid-drive motor, it powers your electric bike through your chain wheel to chain to freewheel, if your chain didn't in good condition, that will increase the resistance and decrease the mileage. Don't you feel much easier after lubing the chain, even riding a normal folding bike? Regularly lubricating the chain can make it easier to pedal and extend your e-bike's range. Don't dry the battery out Try not to dry the battery out often! Nowadays, nearly every electric bike's battery is lithium-ion battery, this type of battery shouldn't run until dead, which will cause damage to your battery permanently, and reduce your battery's mileage. You may not feel the damage at the beginning, but as time pass, after one year you always dry the battery out, and you can feel your battery's mileage is less than before.   Why did I so sure? Because I had done an experiment on my own folding electric bike and two iPhone 13. As for comparison, let me tell you about the experiment between two iPhone 13. Usually, my iPhone often charged when the battery is above 40% and below 90%; my wife's iPhone always gets charged when the battery is below 10% or after shutdown. After one year, my 'battery health' says it can hold 97% of its MAX capacity while my wife's battery just can hold 83%. See the difference? I'm not joking, the experiment won't cheat you. Pedal harder It's easy to know, when you want to go from one place to another place with your electric bike, there are 3 ways: pedal your electric bike yourself; or let the motor 'pedal' for you; or pedal with the motor together. When the motor boosts you up, it needs electricity from the battery, and the electricity stored by your battery is limited, if you want to travel further with limited electricity, the only thing you can do is pedal harder, you do the most effort yourself, let the motor have a rest or at low power.   Gear choice This is a riding technique, when going uphills, you need to switch to lower gears to gain more torque; but when on flat terrains, you can use the higher gears to get a higher speed. This will affect mileage both on Mid-drive or hub motor electric bikes, mid-drive motor electric bikes will have more affection than hub motor E-bike if you didn’t choose the suitable gears while in pedal assist mode. If your electric bike is riding in pure electric mode, this tip can only affect the mid-drive motor E-bike, because the mid-drive electric bike boosts your bike through chain and freewheel. So, you should choose a suitable gear to gain enough torque or speed and keep them in balance through gear reduction.     Riding weight Don't take too many things with you when riding, do those things in need? Ride in short distances that will be almost no difference, but if you have a long way to go, you must consider this.   Ways using the power I can share with you the result of my experiment: When starting up, the motor will consume more power; when traveling at a higher speed, the motor will consume more power. so if it's not so hurried, you can try lower speeds such as 15.5mph, and pedal with the motor when starting up to go further.   Follow for more: qualisports YouTube qualisports Instagram qualisports Facebook

Electric bicycles, also known as e-bikes, have gained popularity in recent years due to their convenience and eco-friendliness. However, with the emergence of artificial intelligence (AI) technology, concerns have arisen about whether machines will eventually take control of these bikes. In this blog post, we will examine the potential for AI to control e-bikes and the societal implications of this technology. The Current State of E-Bikes E-bikes are currently powered by electric motors that assist the rider's pedaling. They have a range of approximately 20-50 miles per charge and can reach speeds of up to 28 mph. E-bikes have already begun to disrupt the traditional bicycle industry and are being utilized by commuters, delivery drivers, and leisure riders alike. The Potential for AI Control As AI technology continues to advance, it is feasible that e-bikes could eventually be controlled entirely by machines. This would require sensors and algorithms that monitor the rider's movements and adjust the bike's speed and direction accordingly. While this may seem like science fiction, some companies are already developing autonomous e-bikes.  The Benefits of AI-Controlled E-Bikes There are several potential advantages to having AI-controlled e-bikes. Firstly, it could enhance biking safety by reducing the risk of accidents caused by human error. Secondly, it could make biking more accessible to people with disabilities or those who lack confidence in riding alone. Additionally, AI-controlled e-bikes could optimize routes based on traffic patterns and weather conditions, making them more efficient and reducing congestion on roads and bike paths. The Risks of AI-Controlled E-Bikes However, there are also risks associated with AI-controlled e-bikes. One concern is the potential for hacking or malfunctioning, which could lead to accidents or intentional harm. Another risk is the loss of control and autonomy for riders. If e-bikes are completely controlled by machines, riders may feel like they have no say in how the bike operates or where it takes them, leading to a loss of freedom and enjoyment in biking. In conclusion, while the concept of AI-controlled e-bikes may seem far-fetched, it is a possibility that we should consider as technology advances. There are both potential benefits and risks to this type of technology, and it is important to carefully evaluate them before fully embracing it. Ultimately, the decision of whether to adopt AI-controlled e-bikes will depend on our societal values and priorities, such as safety, efficiency, autonomy, or something else entirely.

Brake components are crucial for ensuring our safety while riding a bicycle. Among them, the disc brake system has become the standard configuration for sports bicycles and is the most critical part of the entire braking system. Unfortunately, many cycling enthusiasts overlook the importance of the disc brake system and are uncertain about its function, maintenance, and how to differentiate between various sizes. In this article, we will delve into these topics and provide a detailed overview of the disc brake system for all cycling enthusiasts to understand and appreciate. What is a disc brake used for? In cycling, a disc brake is used as a braking system for bicycles. It is a type of brake that uses a rotor, typically made of metal, that is mounted on the wheel hub and a caliper that is mounted on the frame or fork. When the brake lever is pulled, the caliper squeezes the rotor, creating friction and slowing down or stopping the wheel. Disc brakes are becoming increasingly popular in cycling because they offer several advantages over traditional rim brakes. They provide more consistent and reliable braking performance, particularly in wet or muddy conditions, and they require less maintenance over time. Additionally, they are typically more powerful than rim brakes, which can be important for riders who are cycling at high speeds or carrying heavy loads. Disc brakes come in two types: hydraulic and mechanical. Hydraulic disc brakes use fluid to transmit the force from the brake lever to the caliper, while mechanical disc brakes use a cable. Both types can provide excellent stopping power, but hydraulic disc brakes are generally considered to be more powerful and offer better modulation. Overall, disc brakes are an important component of modern bicycles, and they can significantly improve the safety and performance of riders on the road or trail. What is the difference in size of disc brake rotors? The disc brakes of bicycles are usually divided into sizes of 140mm, 160mm, 180mm, 203mm, and 220mm. For road bikes with hydraulic brakes, 140mm and 160mm disc brakes are the most common. Considering that mountain bikes require more braking power and the tires can provide more grip, disc brake sizes generally start at 160mm. The current mainstream trend is to use larger 180mm or even 203mm (200mm) disc brakes on the front wheel of XC(Cross Country) mountain bikes to further enhance braking power. Generally speaking, the larger the disc, the longer the brake lever when braking, the greater the braking force and the more efficient it is. Based on current trends, larger brake discs can provide more braking force, which is not in dispute. Under other conditions remaining unchanged, simply increasing the size of the disc can obtain more braking force. This is because a larger disc can provide a longer lever arm for the brakes, or a larger brake radius. What are the benefits of a thicker brake disc rotor? Increasing the size while maintaining braking power ensures better resistance to twisting forces. A thicker disc rotor has a greater oil capacity for heat dissipation. A thicker disc rotor is less likely to vibrate or generate noise due to resonance. It is more rigid and has a stronger ability to resist deformation. Pairing a more powerful caliper and brake pad with a stronger disc rotor results in a more linear and powerful braking force. Compared to a 1.8mm thick disc rotor, a 2.3mm thick disc rotor has an 8% improvement in heat resistance, a 47% increase in rigidity, and provides stronger braking power. It's important to note that there are tradeoffs to using thicker brake discs, such as increased weight and potential compatibility issues with certain bike frames or components. It's always best to consult with a professional bike mechanic to determine if a thicker brake disc is right for your specific bike and riding style. How to install the brake disc? Installing the bike brake disc involves a few steps, and it is important to follow the manufacturer's instructions carefully to ensure proper installation. Here is a general guide to help you install a bike brake disc: Gather the necessary tools: You will need a torque wrench, hex wrenches, and a rotor truing tool. Remove the wheel from the bike: Use a hex wrench to loosen and remove the axle bolts, then slide the wheel out of the frame. Remove the old rotor (if applicable): If you are replacing an old rotor, use a hex wrench to remove the bolts that hold it in place. Install the new rotor: Slide the new rotor onto the hub, lining up the bolt holes with those on the hub. Tighten the bolts using a torque wrench, following the manufacturer's recommended torque specifications. Mount the wheel back on the bike: Slide the wheel back into the frame, ensuring that the axle is properly seated in the dropouts. Tighten the axle bolts using a torque wrench, following the manufacturer's recommended torque specifications. Adjust the brake caliper: Use the rotor truing tool to align the brake caliper so that it is centered over the rotor. Tighten the bolts that hold the caliper in place. Test the brake: Squeeze the brake lever to ensure that the brake engages properly and does not rub against the rotor. If the brake rubs, use the rotor truing tool to adjust the caliper until it is properly aligned. Once you have installed the brake disc and tested it, you are ready to ride your bike again. If you are unsure about any of these steps, it is always best to consult with a professional bike mechanic for assistance. How to maintain the brake disc? Maintaining your bike brake disc is essential for ensuring your safety while riding. Here are some steps you can take to maintain your bike brake disc: Keep the brake disc clean: The brake disc should be kept clean to prevent any buildup of dirt, debris or oil. Use a clean, lint-free cloth or paper towel to wipe the brake disc before and after each ride. Check the brake pads: Regularly check the brake pads for wear and tear. The brake pads should be replaced if they are worn down or damaged. If the brake pads are dirty or glazed, remove them from the caliper and clean them with rubbing alcohol. Inspect the brake caliper: Check the brake caliper for any signs of damage, such as cracks or deformation. If the caliper is damaged, it should be replaced. Lubricate the moving parts: Lubricate the moving parts of the brake system, such as the brake lever, cable and caliper, to ensure smooth and efficient operation. Check the rotor for warping or damage: Check the rotor for any warping or damage. If the rotor is warped or damaged, it should be replaced. Adjust the brake pads: Adjust the brake pads to ensure that they are properly aligned with the rotor. The pads should be adjusted so that they make contact with the rotor evenly and do not rub against the rotor excessively. By following these steps, you can maintain your bike brake disc and ensure that your bike is safe and ready for your next ride. Please take note of the following safety guidelines: After riding, do not touch the brake disc with your hand as it may cause burns. Allow the brake disc and brake pads to run in for a period of time before applying heavy braking. Avoid installing new ones and immediately subjecting them to intense pressure.

The mechanical structure of hydraulic disc brakes is more precise and complicated than that of C brakes, so riders are not recommended to replace them on their own except for simple debugging.    Problems commonly encountered with hydraulic disc brakes include strange noises, improper trips, air mixing, oil leaks, overheating, etc. Generally speaking, other than the strange noises associated with calipers, other problems can be described as "oil" related.   Over-tightened brakes Newly purchased electric bikes with mechanical brake and e-bikes with hydraulic brakes may have the problem of small gaps and tightness. You can try break-in method: choose a flat and open outdoor road, ride the bike to a speed above 10 mph, brake hard to walking speed, i.e., about 3 mph, repeat 20 times; then ride the bike to a speed of about 15mph, apply the brakes to the end, repeat 10 times, the break-in will be over, and you will feel the braking effect getting better.  Our four models of folding electric bike hardly have those problems, such as 16 inch folding e-bike Nemo, 20 inch folding e-bike Volador with mechanical disc brake, and 20 inch folding e-bike Dolphin, 20 inch fat tire folding e-bike Beluga with hydraulic disc brake, we will adjust all parts before leaving the factory, just enjoy your ride.   Brake noise The problem that causes brake noise is mainly due to improper installation position or the caliper is mixed with mud and foreign matter. We can solve this in order by elimination method.First, check whether the disc is located in the middle of the two lining pads, which the knob on the caliper can adjust; then, check whether the disc is deformed and deflected. A slight deformation can be corrected or replaced with a new disc; finally, check whether the wheelset is correctly installed. If there is deflection, the wheelset must be reassembled.If there is no problem in the first step, proceed to the second step: clean the caliper disc and replace the liner plate. First, we can remove the brake lining pads and wipe the pads and discs with a liquid mixture of alcohol in equal proportions. Then dry them with paper towels; secondly, check whether the pads are stained with oil and if they need immediate replacement. Watch the video below if can help you:   Brake system full pressure Full pressure in the oil disc means that the oil circuit is overfilled with oil or absorbs water vapor, especially DOT brake fluid, which is highly hygroscopic. As time goes by, the pressure of the fluid line that absorbs moisture rises, resulting in smaller and smaller gaps and poor rebound of the lining, which makes it easy for the wheels to rotate poorly and hold when the brakes are applied, causing potential danger.We can replace the oil. This is suitable for vehicles that have not been ridden for a long time and for vehicles that have been changed more than half a year since the last oil change. The oil quality has dropped significantly, and in this case, the brakes and discs will rub excessively, so a new oil change is more effective; or drain the oil properly. Loosen the oil filler screw at the oil filler hole on the brake handle, and the excess oil will spill out naturally. Wipe the oil with a paper towel to tighten the screw. If the wheel is hard to turn, we can repeat this step until the wheel turns smoothly. Too much trouble? let me tell you a good news: All Qualisports electric bikes with hydraulic brake, are using mineral oil, but attention, do not mix them together.   Brakes out of fluid and air Due to the damage to the oil circuit, disc brakes will be short of oil or mixed with air, which will lead to a soft grip and weak braking. Then, we need to expel the air and replenish the oil. At present, except for some brand like Shimano hydraulic disc brakes which use mineral oil brake fluid, some other brands use DOT oil. The boiling point of mineral oil and DOT oil after absorbing moisture are both lower (such as DOT4's dry boiling point is 446 ℉, and the so-called wet boiling point is the boiling point after mixing with water. The more water content, the lower the boiling point), resulting in frequent braking under the oil circuit heating up and boiling after damaging the oil pipe, especially the oil pipe connected to the caliper, more likely to leak oil and mix with air.If there is air in the uppermost part of the oil circuit, you can use a needle syringe to inject the corresponding oil and fill it up. You can choose discs with better heat dissipation using mineral oil disc brakes to avoid boiling and oil leakage.How do we determine if the oil brake is leaking? An oil stain on the surface of the brake does not necessarily mean an oil leak. We also need to judge whether the oil leak is confirmed according to the actual situation after the oil disc is actuated.First, we must do some preparation work: clean the hydraulic brake. Wipe off the dust on the handle with alcohol wool. Next, we need to make a preliminary judgment on the clamp end and carefully observe whether there is oil leakage from the four clamp parts.The first part is to observe the position of the seam of the clamp. If there is oil, it may be caused by the damage or leak to the upper and lower seat seals.The second part is to observe whether there is oil leakage from the joint screw patch. Excessive deformation and rupture of the brass sleeve, improper assembly of the oil tube, and slipping of the screws can also lead to oil leakage.The third part is observing whether oil is oozing out of the oil leak nozzle. If there is oil, it may be that when locking into the oil spout screw, the teeth seam is stained with mineral oil. After riding or the external temperature is too high, the oil is discharged outward, and dirt is attached to it, mistaking it for an oil leak. In the last part, carefully remove the brake lining and check if there are oil stains on the back plate of the lining. If there are oil stains, it is likely that the piston is leaking oil and needs further determination. We need to use an alcohol cotton ball or ultrasonic cleaning machine to clean the inside and outside of the clamp, then spray the surface of the oil disc with an air gun to keep it clean, install the oiling block and press the brake to check if it is solid. If it feels soft, you need to make up the oil. After making up the oil, you also need to clean up the oil stains to avoid misjudgment.If there are persistent bubbles on the edge of the upper and lower seat pistons and oil stains when the block is removed, the clamp must be leaking oil, and the whole clamp set needs to be replaced. If there is no oil stain and no air bubble in the piston area, there is no oil leakage.Next, we need to determine if the brake handle is leaking. Operate the brake handle 5~10 times and observe if there is any oil leakage from the three screws. Improperly assembled oil groove washers or deformed washers can lead to oil leaks. Continue to operate and observe if oil is coming out of the oil groove cover. Then observe whether oil flows out from the piston part of the handle. Debris on the aluminum piston seal and piston surface can cause the aluminum piston to wear and leak oil. Observe whether there is oil seepage from the handlebar connecting the screw part. If there is oil seepage, it may be caused by deformation and rupture of the copper sleeve or improper assembly of the oil tube. If there is oil leakage in the above handlebar parts, then the whole handlebar set needs to be replaced.When your bike encounters a problem, it is recommended to be referred to a professional repair store to ensure that your bike's brake system can operate safely.  Qualisports have been focused on manufacturing high quality folding electric bicycles for more than 5 years.

For the first batch of Dolphin STD/PLUS, there are three tips we would like to share with all Quali-bikers for a better riding experience.   1. Non-zero Startup The first batch of Dolphin STD/PLUS comes with the default setting of Non-zero Startup, which means the ebike won't run by pressing the throttle control while it stands still. In other words, it needs some external force to get an initial speed and start running. (The throttle won't be enabled until the bike is moving and PAS working.) Non-zero Startup is settled for safety concerns and can prevent injuries caused by accidental touching of the throttle.   2. Sequence of Consuming the Battery Dolphin Plus comes with a dual battery mode and two batteries. One is a removable 48V 7Ah tube battery, while the other is a 48V 10.5Ah seat post battery. There is a Power Button on the tube battery that you need to press manually every time you want to use it and make sure the battery is well secured in the frame. For example, you can pull the handle of the tube battery to see if it’s secured tightly. Otherwise, the BMS cannot recognize it and automatically switch to the seat post battery. When both batteries are powered on, the smart BMS will first consume the tube battery, and the Display will only show the battery capacity of it. When the tube battery gets depleted or the BMS monitors that the voltage drops under 41V, it will AUTOMATICALLY switch to consume the seatpost battery without rider intervention, and the bike gonna nonstop continue to run. Also, please note this: Due to the tube battery not automatically turning off after each ride, please turn it off manually via the Power Button, or it will remain in standby status.   3. Ways of Charging batteries 1) Charge the seat post battery separately.There's a charging port on the top of the battery; uncover the cap and connect it to the charger. When the charger is plugged into the socket, you will see the indicator light turns red from green. The indicator light will turn green from red when the battery is fully charged. The seat post battery can be charged on the bike or taken off and charged separately in your room or office.2) Charge the tube battery separately.You need to unfold the bike and take the tube battery out of the frame first. There's a charging port at the end of the battery; uncover the cap and connect it to the charger. The indicator light turns red from green when the charger is plugged into the socket. The indicator light will turn green from red when the battery is fully charged.3) Charge two batteries simultaneously.There's a charging port on the controller box. Uncover the cap and connect it to the charger. When the charger is plugged into the socket, the indicator light turns red from green. The BMS will choose to charge the tube battery first. When this charging finishes, the light turns green for a while and then back to red to start charging the second battery.   We welcome all Quali-bikers to share your riding experience with us, and we are looking forward to your feedback on Dolphin STD/PLUS. Hope these tips are helpful to you.

Doing a basic but thorough safety check on your bike before every ride is always a good idea. After all, you don't want to find out something wrong when you're already on the road.  The "M-check" method will help you methodically identify possible problems with your bike memorably. This applies equally to the road, mountain, electric hybrid, and other bikes that have been sitting idle for a long time.   The M-check is a set of check methods designed to address a bicycle's basic safety and performance. Starting from the front hub, moving up along the front fork, then backward, passing through the frame and finally to the rear wheel, drawing the shape of the letter M, you can traverse the main working parts of the bike and complete the inspection of the whole bike. Once you have mastered this method, you can check a bike thoroughly in a couple of minutes. Following is each step of the M-check:   1. Check Front Wheel, Brakes, and Hubs First, we need to check if the wheelset is securely fastened. The most common way to lock the wheelset on a bike is with a quick release or thru axle. If you are using a quick release on your bike, loosen and open the quick release, press and hold the toggle switch on the quick release and turn the nut on the other side of the quick release until the nut is tight against the fork. Then open the quick release and screw the nut in one more turn. Your wheelset will now be securely locked to the hook and claw of the fork. Placing the bike on the ground while doing this check and adjustment will better ensure the wheelset is centered. There are many different types of thru axle. Some have a locking structure similar to a quick-release cam lever, and others use threaded locking; they serve the same purpose. The shaft is usually threaded through the entire hub from the fork side and locked to the opposite or rear fork. Before riding, ensure the thru axle is securely locked per the manufacturer's instructions.Second, turn the wheelset to see if there is a squeaking sound. It may need maintenance or bearing replacement if it sounds like it is turning roughly. As you spin the wheelset, check to see if the brake discs or the brake side of the rims are rubbing against the brake clamps. You will need to adjust the clamps or the entire brake system if it does. Last, squeeze the brake handle to ensure the brakes are working correctly. If you find that your hydraulic disc brake feels soft, then it may need to be oiled. The hydraulic disc brakes on your new Dolphin need to be oiled regularly. If you are using pull-cord disc brakes and they don't feel as sensitive as they used to, you may need to adjust the tension on the brake lines or replace the brake pads.   2. Check the Tires The tire needs to be properly mounted on the rim. Check the edge of the tire that is in contact with the rim to ensure that the edge looks even in every place. If there is a problem somewhere, then it needs to be removed and reinstalled. After completing the inspection of the tire mounting, we need to check the tread and sidewalls of the tire in contact with the ground for excessive wear and damage. It is dangerous to use tires that are excessively worn or have damage, such as cracks, and if you find any suspicion or uncertainty about the tires, we recommend replacing them.   For road bike tires, if you notice that some areas have worn flat or where the rubber is starting to come off, the tire must be replaced. For fat tires or mountain bike tires, the tires' bumps will gradually disappear as they wear. If the bulge has worn down very badly, then the tire is no longer usable. You also need to pump the tires to the right air pressure before riding. The optimal tire pressure will be different for different models such as road bikes and mountain bikes, including the different surfaces you are ready to go riding on.   3. Check the Frame Check the frame to see if there are hairline cracks, and go down the edge to check if the various accessories (such as the water bottle cage) are installed correctly and if there is any noise. Even if there is a tiny hairline crack, you need to have it checked by a professional before riding. If your frame is equipped with a rear shock, check the shock mounting screws to ensure the shock is correctly and reliably installed. You also need to test the shocks to ensure they are working properly.   4. Check Cranksand Pedals Check if the crank is free to rotate: rotate the crank backward to check if the drivetrain runs smoothly and if the bottom bracket is in good condition. Check the gear plate for damage, missing teeth or excessive wear. An excessively worn tooth is similar in shape to a shark fin. Wiggle the crank to the left and right sides of the bike to check for any resistance or openness in the connection between the crank and the frame. If it feels like there is open volume, it means you may need to replace the center shaft. Turn the pedal, and a well-maintained pedal will only rotate freely with damping because thick lubricated grease will prevent the pedal from rotating. Also, check that the pedals are properly and reliably mounted on the crank. For locking pedals, check if the locking shoe's metal or plastic locking tabs are excessively worn, if the bolts are secure, and if the locking and unlocking forces of the locking pedal match your locking pedal settings.   5. Check the Seat Tube Cushion There are many small parts on the seat rod clevis, and they can easily move relative to each other and then make a squeaking sound. If so, we need to take apart all the various parts on the seatpost, clean them, lubricate them, and reassemble them. We need to regularly remove the seat post from the frame for cleaning and maintenance. If you take care of your seat post regularly and properly, your frame will be protected, so don't be lazy and ignore this step. After setting the correct cushion height and reassembling the cushion, we need to check if the cushion is firmly installed on the cushion clevis.   6. Check the Rear Wheels and Drivetrain Turn the crank to check the chain rotation to ensure no chain links are frozen and cannot turn against each other. Double check each gear of the shifter to make sure that each gear is raised and lowered properly. If using electronic shifting, ensure the battery is fully charged before riding. If there is no indication and you are not sure, it is best to charge it in advance. Safety should be your top priority, and checking your bike regularly will also help reduce the chances of breakdowns and expensive repairs, allowing you to enjoy the freedom of riding on two wheels. There are many things to check before you go out on your bike, but it only takes a few minutes at a time. When we install the saddle on the seat post battery, we should confirm the bottom battery cable is unconnected; otherwise, we need to loosen it first. And please keep in mind not to use any screwdriver to touch the charge port on the seat post battery in case of electric shock.

An electric bike is not only a daily commuter but also a very important partner. It brings various convenience to our life, and also brings us health as it helps us to get more exercise. So it is important to pay attention to regular maintenance and cleaning so that your electric bike is always in the best condition. Every bicycle needs cleaning and your Qualibike is no different. Some riders may wonder how often should we clean the e-bike. The answer depends on the frequency of using the bike and the type of terrain on which you ride. Regular cleaning and maintenance can keep the vehicle in a good range of service life. The following tools are usually used to clean folding bicycles: wrench tool, toothbrush, chain oil, transmission cleaner, and car wash wax.   1. Cleaning Body One of the first and most common tasks is to clean the body. It is often recommended to wash it directly with a water gun. However, we are more accustomed to the practice of picking up a bucket of clean water, dripping in some car wash wax, and then slowly wiping the entire body with a damp towel. The process might be slow, but it has its benefits: on the one hand, you can carefully check the overall condition of the vehicle, and in the process of wiping, you can find any knocks or obvious faults that need to be repaired; on the other hand, wiping can avoid a lot of water impacting other transmission parts and avoiding noise from the transmission center shaft or bearings. Cleaning the bodywork is just the first step and can be done easily with wiping. A clean folding bike is not only enjoyable to ride, but it also reduces the damage caused by the long-term lack of cleaning. 2. Cleaning Transmission After cleaning the body, we will focus on cleaning the transmission part of the folding bike, which mainly contains flywheel, chain and guide wheel. For those who pursue the ultimate cleanliness, they are used to removing the flywheel, chain and guide wheel parts for cleaning. However, in daily life, sometimes we do not have the conditions to disassemble the parts and cannot take them down for cleaning, so we prefer to clean them with a toothbrush after spraying the cleaner. There are a very large number of transmission cleaners on the market, usually with a spray nozzle bottle design. Turn on the nozzle switch, aim it at the parts to be cleaned, spray some cleaner and leave it for a while so that the cleaner can dissolve the stubborn oil stains on the parts. For stains that can't be dissolved, you need to scrub them repeatedly with a toothbrush, and this is the step where you will feel the most accomplished. It's easy to get great satisfaction from seeing the previously dirty flywheel start to regain its silver color after some cleaning. You can take a discarded hard card and wrap a rag around one end of it so that you can easily clean the stain from the middle crevice of the flywheel. 3. Checking Brakes Brakes are one of the things we focus on every time we do maintenance, after all, they play a vital role in the riding process. An excellent brake feel not only maintains a better braking effect, but also gives you a safer chance in case of emergency braking. The brakes are relatively simple to tune. When the wire pulling disc brake is found to be inappropriate in strength, you could check where it most likely needs to be tuned by controlling the variable method. Generally, you need to check if the brake clamp is too large. By adjusting the position, you can easily adjust the brakes to the feel you need. You can also adjust the brake cable strength to maintain a good feel. The maintenance of hydraulic brakes is a bit more complicated, you need to check the brake fluid on the brake handle for air or insufficient brake fluid, and sometimes you may need to change the brake fluid.   4. Checking Shifting Another factor that affects the ride is the shifting effect and feel of the transmission. A folding ebike that has not been maintained for a long time is prone to poor shifting and even some gears not shifting properly. If you can't replace the shifting cable, you can also control the shifting effect by adjusting the strength of the rear derailleur limit screw. Usually we will screw half a turn for one dimension, and check if it can be shifted properly after screwing.   5. Whole Bike Inspection After completing the above actions, most of a routine maintenance is over. What remains is a detailed inspection of the whole bike: check whether the tire pressure is normal, whether the seat tube needs to be cleaned, whether the screws of each part are loose, whether the safety function of the folding buckle is normal, etc. Through maintenance, we can keep our bikes in the best condition for a long time, which in turn will benefit our next ride, and it can accompany us to see more distant scenery.

Latest updated time: 03/26/2024   In recent years, lithium-ion batteries are gaining popularity for their lightweight, environmentally friendliness, and long life. As we all know, the battery is an integral part of the e-bike system. It stores the electricity in it and boosts you up with the motor. When the battery gets to the end of its life cycle, it won't stop working immediately, you will find you can get 30 miles before, but now just can go 25 then 20 or less on a full charge.   Something you must know before you read this article: 1, All li-ion battery life is limited, depending on our actual use, it might be shorter or longer. 2, All li-ion batteries begin ages after they are born, even if not used. 3, One charge cycle is counted as charging the battery from 0% to 100%. 4, Usually, a Li-ion battery can reach 600 to 800 cycles (sometimes more).   To extend the battery's life, here are some tips for you to refer to:   Try to avoid high-current discharge   If you ride an e-bike in pure electric mode, the faster you go, the higher current the battery takes; the higher current result in lower battery efficiency. The same as going up hills, the steep the incline is, the higher current will be.   When at 10 mph, the battery discharge at about 3 Amps, efficiency is around 99%; 15 mph at 5 Amps with 95% efficiency; 20 mph at 8 Amps with 90% efficiency. *Tested on a 48V 500W(rated) motor, there will be differences.   We have done an experiment on an e-bike equipped with a 48V 13Ah battery; in pure electric mode, it can reach 51 miles when kept 16 mph, if at 31 mph, just can reach 23 miles. See the differences? The battery's efficiency when at 31mph just reached 89% of 16mph, that's the result of a higher discharge current for the battery.   Frequent acceleration especially full-acceleration also will drain the battery in a high current, when cruising at 10mph, output power is around 150 watts(current 3 Amps); when full-acceleration from standstill, output power(peak) is around 750 watts(current 15 Amps).   So, try to maintain a suitable and constant speed to keep the battery working steadily, it can make your battery last longer.   Try to avoid a deep discharge rate   Many factors can affect the life of the battery, one of the most important factors is the depth of discharge. A study published by Cadex Electronics described that a Lithium-ion battery would have a 50% longer lifespan if it is charged after 50% discharge instead of fully discharged(like dropping to 0%). What's more, charging after only a 25% discharge rate resulted in a 67% longer lifespan!   So, try not to dry it out totally, like discharge it way down to 0 % before recharging it, According to many articles and experiments, the lithium-ion battery doesn’t like being fully(deep) discharged; try to avoid draining your batteries below 25% when possible.   For example, I had done an experiment: On two iPhone 13 which also use the lithium battery. Usually, my iPhone always gets charged when the battery is around 50%, and my wife's iPhone always gets charged around 1% or after shut down(0%); After one year, my Battery Health says it can hold 97% of its MAX capacity while my wife's battery just can hold 83%. See the differences?   By the way, If you use 25 percent of the battery’s capacity, then recharge to 100 percent, you can do this 4 times to reach one charge cycle.   Try to charge the battery up to 80%   To maximize battery life. It is better to charge to 80 percent if you know you don't need a full battery(Pro tip: Chargers are less expensive and last much longer. If you're considering the purchase of a second battery to keep at the office, buy a second charger instead.).   Most would agree that you will get more charge cycles if you charge your battery to 80%; in my experiment, I charged 100% every time, because I think the battery is just for me to use, and I want to go anywhere any time I want, enjoy my life. From the test result I did on two iPhone, this makes a little difference.   But if you want, you can get a Timer, we all have better things to do than to sit and watch a battery charging; many Timers can cut off the power automatically, so get yourself one and set it for hours when charged nearby 80%   Lithium-ion batteries have NO memory effect, this was for Nickel Cadmium batteries that went out of style decades ago, yet this is a surprisingly common question people ask about any rechargeable battery. Learn more: Lithium-ion batteries do not have “battery memory”   Store batteries charged at 50%   Are you not using your e-bike for a longer period of time? Avoid leaving the lithium-ion battery in a state of long-term power loss, this will result in a much-reduced lifespan for sure. Try to keep your battery charged between 40% and 60%.   Unlike most other battery types (especially lead-acid), lithium-ion batteries do not like being stored at high charge levels   For storing batteries long term, charge them to about 50% and check on them every 2 to 3 months, Is it below 40%? (the battery will self-discharge over time), if so, give it a booster charge to return to the 50 percent range.   Store batteries in a cool & dry location   Try to keep your batteries cool whenever possible, Storing at temperatures higher than 185℉ or lower than -49℉ can be really bad for your e-bike battery.   This is why it is important not to leave your battery in the car, during summertime, the inside of your car can exceed above 140℉ in 20 to 30 minutes under direct sunlight, the highest even reaching 186℉. Keep an eye on the temperature. even The best BMS in the world can’t keep a battery from frying in a 186℉ car.   It is recommended to store your batteries between 0-40℃, which is 32-104℉.   To Summary  • Try not to discharge to 0% often • Charge your battery to about 80% to get more cycle life. • All batteries get ages naturally, whatever is it used, just buy it when you need to use it.  • Get a larger battery if possible, so you can still get enough range and high cycle life by light discharge. • Avoid exposing your battery to high temperatures and store it in a cool and dry place with 50% charged.   Keep in mind you can do all or none of the above, the bike will still work fine, but the battery may not live as long.  As time goes on, battery management systems (often referred to as BMS) and smart chargers get better and better, allowing you to be more carefree with the battery.

We have been enduring the so-called hard days after the striking of Covid and the unexpected catastrophic climate. Technical recession in the economy, consistently rising energy bills, and drought are already parts of our daily life. At this moment, we have to consider taking every single step to control our life consumption. WHY E-BIKES? Why not e-bikes? When you are struggling out of the long line of cars, the soaring gas price, and even the grinding parking, you may need to consider how to hold back your annoyance smoothly. For the E-bike journey, plenty of reasons stand for it. Chill out. We are not persuading you to ditch your cars and turn to e-bikes solely. What we do is to show you another attitude and solution towards commuting or living. Though it was not your first choice for daily transport till now, considering its contribution to global sustainability, we suggest you take a trial on it.   A small change means a big contribution to the blue planet Vehicles powered by unsustainable energies often produce dangerous chemicals like carbon monoxide, nitrogen oxide and hydrocarbon, which are also the pathogenic substances of some human diseases, such as tuberculosis and asthma. With the advancing technology of rechargeable and recyclable batteries, we can not only enhance the performance of e-bikes but also improve resource utilization. Therefore, there is no more waste in electric bikes. Upon the ride, each mile you pass would save around half a kilogram of carbon dioxide emission compared to car driving.  According to NOAA, July 2022 average global surface temperature was the sixth warmest for July since international records began in 1880. Most of the contiguous U.S. had warmer-than-average record-warm temperatures last month, marking this the third-warmest July in the lower 48 states. If we do not take any measures now, the record will definitely be refreshed one by one. However, once we hop on our e-bikes, we will significantly reduce the harmful fumes produced by vehicles and industries. To avoid more air and noise pollution, you can pick up an electric bike that fits you well, which will help sustainable development.   More convenience and benefits in such a challenging period Since the outbreak of COVID-19, most people have been having difficulties of commuting, especially on public transport. Restrictions like social distance will only make your commute longer and harder. Plus, with the soaring gasoline price that has risen to $4.599 a gallon on the day and even higher in the future, a portable and eco-friendly e-bike can be a good investment. Even if some people use a mixture of e-bikes and cars, it can save them a little fortune in the long run. In addition, with a light but powerful e-bike loaded with advanced PAS technology, riders can reach farther places without soaking their clothes. And compared to average bikes, you do not need to worry about the time cost. You can easily reach your destination on time with a light pedal or twist of the throttle.  The French government has released the latest scheme to provide up to €4000 subsidy for those families who plan to purchase eco-friendly folding E-bikes. President Biden issued the Inflation Reduction Act which covers $375 billion for the climate change fight. With increasing government support, it is the best time to choose E-bike for the future.   WHY QUALISPORTS USA? Having been in business for more than 8 years, Qualisports USA is a bunch of energetic and green people committed to trying everything possible to support sustainable development and build quality folding e-bikes.  Quality is in our name, and we build our products with quality parts inside and out.

Upon their release, they gained an excellent reputation in our community. Nemo and Volador are like your Bluetooth or AirPods, which can be taken with you more easily. While Dolphin and Beluga are more like power banks or portable chargers, which will guarantee longer usage for your activities.   There is no push stronger than the trust and support of every respected customer. We are so proud that we have won the reviews and made many friends on the way to success.If you are interested in riding but not know much about folding e-bikes, feel free to contact us in the social community.

Last update time: 20/4/2023 In order to protect the environment, build cleaner cities, and improve the quality of resident's life, we should drive less and exercise more. Electric bicycles are the perfect choice for those drivers who are not too far away from their destinations. Also, it is a good choice for those who take their children to school and won't get stuck in traffic jams. Electric bikes can provide fast and efficient personal transportation. And most important, the rebate programs many US states have launched, can help reduce the cost of some expensive e-bikes, and let electric bikes more affordable to anyone than ever before. Looking for high quality electric bike in USA? Click here. When a national electric bike subsidy looked likely to last year, but finally failed. The good thing is, there are cities and states picked up. Vermont is the first state who launched the incentive program for electric bikes in the US. I think this is the exactly way how money should be spent, If you want to make efforts to invest in your state, by improving roads, improving resident's health and improving lives, be environmentally friendly, invest in transport like electric bikes, electric scooters will be a good choice. Most states adopt the same class 1,2,3 e-bike laws, so make sure you are aware of e-bike's class before purchasing an electric bicycle.   Quick look for e-bike rebates by states:   Texas                     California                      Colorado                   Connecticut Hawaii                   Massachusetts             Ohio                           Virginia New York              Oklahoma                     Rhode Island              Vermont Oregon                 Tennessee   Texas This state didn't have any statewide programs yet. But Austin does have substantial programs. For example, Austin Energy E-Ride rebates details are below:   For individual: $500-$999 e-bike gets a $200 rebate $1000-$1999 e-bike gets a $400 rebate $2000 and above e-bike gets a $600 rebate   For Individual Customer Assistance Program (CAP) Customers: $500-$999 e-bike gets a $300 rebate $1000-$1999 e-bike gets a $700 rebate $2000 and above e-bike gets a $1300 rebate   For riding fleet: $500-$999 e-bike gets a $400 rebate $1000-$1999 e-bike gets a $600 rebate $2000 and above e-bike gets an $800 rebate   Rebates above are affected since January 1, 2023. Also, there are restrictions such as you must receive electricity from Austin Energy, the electric bike must be new and must be purchased from Austin Energy's approved dealership list, incentive application must be submitted within 60 days of your purchase. For the riding fleet, there will be more restrictions: one must purchase between 5 to 25 qualified electric bikes and each e-bike of the fleet must display Austin Energy branding, all electric bikes must be in service for at least one year(exclude those e-bikes damaged beyond repair).   California About $10 million rebate in this state, includes class 1,2 electric bikes but excludes class 3 e-bikes. $750 for standard e-bikes, $1500 for cargo electric bicycles, or adaptive e-bikes. What's more, people whose income is below 225% FPL(Federal Poverty Level), or who live in DAC(Disadvantaged Community) are qualified for additional $250 incentives. Restrictions also, the buyer must be a California resident, electric bike stores must be in California, income cap must below 300% FPL.   Colorado It has approved a $12 million rebate, but now I can't find any details yet, latest news I can find said it will be available to individuals early summer 2023, now it is april 2023, it should be coming verrrrrry soon, I guess.   Connecticut This state's rebate for electric bikes is up to $750, this rebate depends on the e-bike price before any taxes or any extra fees. If you want to reach the highest rebate, you might need to purchase an e-bike that cost more than $2500. Restrictions are motor power no more than 750 watts (1 horsepower), pure electric top speed under 20 miles per hour, must be purchased from a store in Connecticut, must only used as personal transit and not for business.   Hawaii The state gives a 20%(up to $500) rebate for electric bicycle and electric motorcycles, but its restrictions seems just suitable for high school students. Buyer must above 18 years old, can not have a vehicle with 4 wheels or more, must be enrolled in school or university.   Massachusetts The rebate depends on your income, from $500(general) to $750(low income), suitable for class 1,2 e-bikes, total rebate is $1 million. If want more details, that will be expected in May or June of 2023.   Ohio I haven't found any statewide programs but city programs, Columbus offers a rebate up to $100 for purchasing an electric bicycle. The total rebate is $250,000.   Virginia This is an odd one I think, the law about this passed in 2021, but the founding never came, and nothing happened since that.   New York For class 1,2,3 electric bicycles, would offer 50% off e-bike purchases, up to $1,100.   Oklahoma If bill SB-435 is passed, it can provide a $200 tax credit towards new e-bike purchasing. Though it is not as attractive as other programs, it is better than nothing.   Rhode Island 75%(up to $1,000) of the cost of e-bike for low income household; for high income, the rebate will be 30%(up to $400). Can apply for class 1,2,3 electric bicycles. The total incentive amount will be $250,000 and the e-bikes must be purchased in Rhode Island.   Vermont The total rebate is $50,000 and $400 for each e-bike, but currently on hold because out of money. Restrictions said that must be a new electric bicycle, motor power must be 750 watt or less.   Oregon The new bill will offer $400 for general residents, people who make 80% of the area median income will be $1,200. The total amount of incentive is $6 million for the first two years, and $2 million of that would be used for rebating the low-income resident. The original bill would have funded a total of 5,000 rebates while the new bill can now fund double, about 10,000 rebates. And not required you own the electric bike for at least one year anymore. By the way, e-bike accessories purchased within the same transaction, such as a helmet or light, or lock, can also be covered by the rebate.   Tennessee There is no statewide program in this state, but Nashville does have programs in play consider a resolution dedicating $1 million of federal COVID founds for electric bike rebates. Basic level rebate is $300 for an electric bike and $500 for an electric cargo bike. The income-qualified rebate is up to $1400 for an electric bike and electric cargo bike, And suitable for class 1,2,3 electric bikes. What is 'income-suitable'? means people earning below 80% of the area median income for Nashville & Davidson County or below 200% of the FPL(Federal Poverty Level) Easy easy, don't be too excited, look at the latest progress in the picture below: 'deferred indefinity' in 4/4/2023.   ATTENTION: All information in the article above comes from an internet search, so it may be delayed, just for reference, for more specific details you should refer to local state release.
