Hi,
I hope someone can help me figure this out. I bought a used bike with a Bafang BBS02 installed. It worked fine when I picked it up but I went to ride it 3 days later and now it doesn't work. Display works, says battery is fully charged but when I hit the throttle it just gives a small jerk and then nothing. Could it be a bad controller? it does the same thing in peddle assist, I peddle it gives a small jerk and no motor. I didn't do anything to the bike from first buying it to trying to ride it 3 days later. it wasn't dropped or left out in the rain. Just sat under a tarp in our shop. Guy claims he just installed the unit last year and only used it sparingly. He has another ebike (also BBS02) that he uses and this one was built in case someone else wanted to ride with him.
