Bafang display error codes

Bafang error 46
Battery too cold

The battery is too cold to use safely.

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.
Battery hot, swollen, leaking or smells strange? Stop and read battery safety first. If there's smoke, get away and call 911.

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.
