When ever I switch the battery on my bafang BBS02 750W ebike it takes off when the peddles are moving, I have no way to change the power level and I can't switch it to no PAS. Trying to program the controller doesn't change anything. Not sure how to fix this?

The controller wires could be shorted out. You can connect two wires in the unit and it will operate without the display. It could be this problem with your controller and then the motor would always be on without listening to the display.

To test this you need to unplug your display and see if it changes anything. If it stops your problem then it's probably your display. If not then it's probably a problem with your wiring. Have fun!
