Most common causes

Battery empty or in deep sleep

A battery that has not been charged for a long time may shut itself off. Charge it fully for at least a few hours. View batteries.

Battery not properly installed or lock turned off

Remove the battery and click it back into place. Check whether the battery lock is set to "on" and whether the contact points are clean. View battery locks.

Faulty charger or charging port

Is the light on the charger not lit, or does it stay green while the battery is empty? Then the charger may be the problem. The C80 charges with the 1-pin Ouxi charger. View chargers for the Ouxi C80.

Loose connector at the handlebars

Check the connector between the display and the wiring harness. Moisture or a partially loose connector is a common cause. View wiring harnesses for the Ouxi C80.

Faulty display or controller

Does the battery work (on another bike or meter), but everything remains off? Then the display or controller is often to blame. The C80, C80 Pro and C80 Mini have the HC80 display. View displays for the Ouxi C80.
