In the process of using electric scooters, I believe that many users have encountered such a problem, that is, the speed of electric scooters suddenly slows down. For example, the scooter can run at a maximum speed of 50km/h, but suddenly it can only run at 30km/h. At this time, many users attribute the reason to the battery is not durable. So, is this really the case? The answer is no. In addition to the battery, these three places also need to be checked.

1. Motor bearing

First of all, the most important thing to check is the motor bearing. If the motor bearing fails, the resistance of the electric scooter during driving will increase, which will reduce the speed of the electric scooter. So, how to judge and solve this kind of problem? The user only needs to rotate the tire. If there is obvious resistance or the tire is shaking from side to side, it is usually a bearing problem, and the speed problem of the electric scooter can be solved by replacing the bearing with a new one.

2. Braking problem

Secondly, the place that needs to be checked is the electric scooter brake. What needs to be noted here is that not only the front brake must be checked, but also the rear brake must be checked. Because the front brake is not used frequently, it is prone to rust, and the brake rocker arm is inflexible and difficult to return. In this way, the driving resistance of the electric scooter will increase and the speed will decrease. Similarly, if there are foreign objects in the rear brake pads, the driving resistance will increase and the speed will decrease. How to judge and solve this problem? Generally speaking, you can check whether there is rust on the front brake. If there is, you can properly add oil and lubricate. In addition, you can check whether there is any foreign matter in the rear brake.

3. Tire pressure

Finally, the area that needs to be checked is the tire pressure. Generally speaking, the most suitable electric car tire pressure for an electric car is 350kpa. If the tire pressure is lower than 300kpa, the driving resistance will increase significantly, which will also slow down the speed of the electric car. How to judge and solve this problem? The user only needs to press the tire with his hands. If it can be pressed clearly, it means that the tire pressure is insufficient and needs to be pumped up.

In short, the sudden slowdown of electric scooters is not necessarily a battery problem. You also need to check the motor bearings, brakes, and tire pressure. If there is a problem with one of them, the speed of the electric scooter will slow down. But no matter where the problem occurs, it is enough to take the corresponding method to solve it.
