Overheating of the electric bicycle controller occurs from time to time. Overheating is always a serious matter, but in a short time, there is no particular danger. However, when it comes to long-term overheating, it might have an impact on the life and the performance of the vehicle, in this case, the e-bike. If that happens, the controller and the overheating need to be put in order. It needs to be solved and checked, and that is done through several different aspects.
Here are some important and useful tips that will help you learn how to keep the electric bike from overheating.
1. Change the cooling system
The first and the most important thing to start with if overheating occurs is to look at the battery. This means that improving the efficiency of the battery as well as preventing overheating is to keep it cool while operating. The easiest way to achieve that is with passive air-cooling. That means having air constantly running over the battery. That means that while you are riding, the air will keep the battery cool and prevent overheating. Many riders decide to keep their battery stored in a bag, that comes in the center of the bicycle frame. Others opt for storing it on either side of the rear wheel. Holding the battery might be convenient, the bag is the one that is trapping the heat inside. This does not allow it to cool, which makes the battery heat up. A better option is storing the battery in an aluminum hard case battery pack. The air will remain inside, however, the aluminum allows transferring much of the heat via convection. The aluminum case batteries have the property to mount directly to the frame or the rack of the bike. That means it is exposed to the air flowing inside the rack that will cool it off.

2. Change the transistors of the controller
Another thing that can contribute to overheating that you need to pay attention to is the transistors. The transistors of the controller can also produce overheating, so it is best to check them and see whether they overheat. If you do not know where they are, look at various video tutorials or ask for professional help.
3. Monitor the temperature of the motor
The motor of your E-bike can also produce overheating. That is why it is suggested to also monitor its temperature and see whether it is working properly. To do that successfully and efficiently, the best way to start with the inspection is to ride at the motor's maximum speed for 20 minutes or more. It approximately takes around 20 minutes of constant load for the motor to reach a critical engine temperature (over 200 F). If you see that the temperature is rising and it is high, then, stop, and rest the motor for about 15 minutes. During this time, the motor temperature will return to normal. After that, continue your ride. Additionally, you can use some different motors to cool down the motor quickly and to prevent the motor from overheating. Be careful with the motor since overheating can cause damage.
4. Don’t flatten your bike tires
Flatten tires, whether they are on the car or an E-bike, do put additional pressure on the vehicle. That means that it will need more power to achieve the desired speed, lose more battery and shorten the riding range. That is why it is important to always look at the condition of your tires. The tires should always be pumped to the suggested level, and never flattened. With the e-bike, riding uphill or on rough terrain will cause the engine and the motor to work under more pressure. Another thing to consider is not to overload the electric bike, which can also lead to flat tires, making the motor harder to work. However, if the high load is short-lived, then, it will not cause damage to any motor components.
Keeping the e-bike in the best possible condition will make it last longer, and provide the quality of the ride that you expect to receive. Overheating is a common issue and problem, that it is not targeted on time, can lead to serious damages of the e-bike, and in some cases, fatal damage to the motor. Like with all other vehicles and appliances, the overheating is the first sign that the products, in this the E-bike, might not be working properly. So, with these tips and suggestions, you can easily stay on top of any overheating problems that might occur. From the first moment, you notice that there is overheating, be sure to cool off the motor and the bike and do proper searches and inspections to see the reason for that. If these tips do not work for you, then, you are required to seek professional expertise and help. However, it is important to stay on top of the problem from the first moment you notice that there is overheating.
