I'd prefer to switch the focus to Bike shops. They seem to HATE electric bikes and won't work on mine. They have great fear of the electrical parts and the motor. Odd. Anyone know why this is?
Because they don't know how to fix it, that's why they won't work on it! They are in the bike business to make money, (not that they can make very much) and they won't make money telling you "sorry I can't fix this, go somewhere else."
