Question 5

Why is there a loud noise from the rear wheel after turning on the bike, but the wheel doesn't spin?

Accepted Answer

This issue typically indicates a motor malfunction. When the motor produces a loud noise but the wheel doesn't turn, it's a clear sign that the motor is faulty. In this case, you don't need to check the power supply or the instrument panel. The solution is to replace the motor. You have two options:

Replace the Entire Motor: This can involve removing the spokes from the wheel and replacing the motor unit.
Replace the Core of the Motor: You can simply open the motor cover and replace the core component, known as the "Core of Motor," which is the central control part of the motor. Replacing just the core is often a simpler and more efficient solution.
