Hello fellow nerds. I have an on going problem with my bbs02 motors. It appears you cannot use the throttle to supplement your speed/power while pedaling with pedal assist. It appears the pas overides the throttle and jerks and jumps erratically. Throttle works fine as long as I'm not pedaling. I've read that reflashing the operating system can work. I'm hoping for an easier fix. I have the reprogramming cable but nothing seems to work. Hope you can help.
