CEMOTO E02 ERROR? Check THESE Before Replacing Parts! — if the player does not load, open the video on YouTube.
What E02 means
E02 means the bike has detected a problem with the brake signal. It does not tell you which part needs replacing, or prove that the brakes are safe to use.
What you can check
- Turn off the bike. Check that both brake levers return fully when released.
- Look for anything blocking a lever, such as a moved handguard, grip or dirt. Do not ride with a bent or sticking lever.
- Look at the visible cables near the levers for damage or a loose connection. Do not open the controller or disconnect the brake safety system.
- If E02 stays on, contact support with a photo of the code and the levers. Tell us if it started after rain, a fall or a repair.
Stop riding if braking feels weak, a lever sticks, or the error remains. Have support or a qualified repairer check it. Do not bypass the brake motor cut-off to make the bike run.
