I have a cube mtb with bosch performance drive motor and today I fell off my bike and bent my rear derailleur causing the chain to go over the biggest cog when shifting and not going into the small cog when shifting up.At first the motor wasn't working but after messing about with my gears it worked again and got me home but after trying to reset my gears with no luck due to a bent derailleur the motor no longer works I need help can a bent derailleur cause my motor not to function.
