What should I do if the scooter makes a sound when it is turned on?
The abnormal sound when the scooter is turned on may be an alarm signal, which may be caused by the following reasons:
1. The wiring around the controller of the scooter is loose.
2. The return of the brake lever is faulty.
3. The controller circuit board is faulty.
4. The connection wire of the battery box is in poor contact.
5. After a certain speed is exceeded, the motor power supply line is cut off.
If the problem still cannot be solved, it is recommended to contact the after-sales service.
