Ouxi C80 display: does nothing or shows an error code

The display remains black, turns on and off, or shows an error code. The display is where the bike shows that something is wrong, but the cause is not always the display itself. Below you will find what you can check for your Ouxi C80 for each cause, and which part you need.

Most common causes

Error code on the display

An error code is a clue, not a diagnosis. The meaning varies depending on the display and controller. View our explanation of error codes and, if in doubt, send a photo of the display via WhatsApp.

Display connector or cable

A damp or damaged display connector or wiring harness often causes communication errors. The pedal sensor, the pedal sensor extension cable, the display, or the controller can also be the cause. Disconnect the connector, dry it, and reconnect it securely. View wiring harnesses for the Ouxi C80.

Faulty display

The C80, C80 Pro, and C80 Mini have the HC80 display. View displays for the Ouxi C80.

Battery and controller

If the display does nothing at all, first check the battery (see "does not turn on"). If it shows an error code about the motor or sensors, the fault is often in the controller or wiring. An undervoltage error code is caused by an empty battery, a loose or damaged extension cable from the battery to the controller, or a faulty battery. There are C80 controllers with a red and with a black motor connector (2024-2025). The C80 Pro has a new controller with a red connector. View controllers for the Ouxi C80.
