Bafang display error codes

Bafang error 81
Bluetooth module error

The display's Bluetooth part has a fault. The bike may still ride normally.

Checked against Bafang's own manual: October 23, 2026.

Check your display first. These are the codes Bafang's own displays use. Many bikes with Bafang or Bafang-style motors have a display made by another company, and its numbers can mean something different. If your display isn't a Bafang one, use that display's manual, or send us a photo.

What Bafang says

The Bluetooth module has an error.

Bafang's recommended steps

  1. If the problem continues, contact your retailer or a shop that works on Bafang systems.
  2. A shop will re-load the display software with BESST, or replace the display.

If it keeps coming back

If the code comes back after a restart, have it checked by a mechanic who works on Bafang systems. Bikes Plus works on Bafang and Bafang-style systems all the time.

Write down the code and what you were doing when it appeared. That saves time at the shop.

Make sure it's a Bafang code

Error numbers mean different things on different systems. This page covers bikes with a Bafang display (the Bafang name or logo is usually on the display or its back), on Bafang mid-drive and hub-motor systems. Displays with a screen keep the last 10 codes in the INFO or ERROR menu. LED-only displays flash the code: the first light flashes the tens digit and the second the units, so two flashes then five is 25.
