    Bafang speed sensor

    I have a new Bafang 1000 watt motor. I also currently am using three other Bafang 1000 watt motors on other trikes. On all three of those trikes, I do not need to use the speed sensor for the motor to work. I never get an error code 21. With the new motor, I can not get it to work without speed sensor. Same console on all motors. I understand how to program motor, but see no settings for disabling speed sensor. How do I remove the need to use speed sensor?

    Hi Bikerbobk,

    And welcome to the forum! :-)


    Sounds like the ever shifting sands of Bafang controller firmware programming. At one time you could work around it by setting the "auto off" time in the display to none. The only other work around I've heard of is with an electronic timer circuit. :-( Sorry.
