Safety acknowledgment

Repair and modification work can cause injury, fire, brake failure, electrical damage, or loss of control.

You must identify your exact scooter and components. Stop if anything conflicts with your scooter or if you are uncertain.

Fix

Start here when a scooter will not run, will not charge, cuts out, throws errors, has weak range, or behaves unexpectedly after a controller, throttle, brake, or battery change.
