Bafang 21H error, no speed displayed or mileage either

And the power/display turns off irregular intervals, 1 mile, 3 miles ?

Thanks

Did you end up figuring out your issue?

Error 21H is a speed sensor fault. For anyone experiencing this issue, there is a troubleshooting guide for Error 21H on the Bafang website here: https://bafang-e.com/uploaded/errcode/202209091016375212.pdf
