I ordered an ebike kit (front hub motor, battery, etc.) from BMS Battery several wks ago and got all my parts today but with no instructions of any kind. I was expecting some awkwardly translated guidelines but got nothing. For starters, does anyone know which side of a Q100 motor the wire comes out so I don't mount it to run backwards? Can anyone recommend an online tutorial that might get me started? Lots of wires! I'm trying to keep it as clean as possible. Do I really need the brake lever switches in my build?
