Frequently Asked Questions

What do electric scooter error codes mean?

Electric scooter error codes (E1, E2, E3, etc.) are diagnostic messages displayed on your scooter's screen to indicate specific problems. Each code corresponds to a different issue, from motor problems to battery faults. These codes help technicians quickly identify and fix problems.

How do I fix an error code on my electric scooter?

First, identify the error code displayed on your scooter. Then power off the scooter, wait 30 seconds, and restart. If the error persists, check all cable connections, inspect for visible damage, and consult the specific error guide above. Many errors can be resolved by reseating connections, but some require professional repair.

Can I still ride my electric scooter with an error code?

It depends on the error. Some codes like E6 (low battery) may allow limited riding, while others like E1 (motor failure) or E4 (brake issues) indicate safety problems that require immediate attention. Never ignore brake-related errors, and always address error codes before riding to ensure your safety.
