Hi,
I bought a Bafang BBS02 750W kit from GreenBikeKit.com a few months ago. Installed it on my bike and everything worked just fine. Then all of a sudden the thumb throttle and the speed sensor stopped working. They both stopped working at the same time. I did not do anything out of the ordinary when it happen, was just about to bike home form the office.
However the motor is still working, I can use the PAS just fine, but the thumb throttle and speed sensor is not working. My display gives me the error 21 after 50-100 meters when using PAS. I can still switch PAS levels, although the display keeps flashing the error code 21. The red light on the speed sensor is not lit like it was when everything was working.
I got in contact with GreenBikeKit who sent me a new thumb throttle and speed sensor. I installed these, but no luck. The problem was still there. That got me thinking it might be the controller that is the problem. So I order a new controller, (750W 48V 25a), and swapped it with my old controller. Still, the thumb throttle and speed sensor is not working. Although the motor itself is working like before (PAS ok). I was absolute sure that with a new controller all would work just fine, but no, that was not the case. How is the possible? What could be the cause of the problem? Could the motor itself have anything to do with this?
New controller, new throttle, new speed sensor, but same problem. I have checked the connectors, all seems fine. Any ideas?
Thanks in advance.
