Some of the Kudos ones are sensorless. Be careful!need a 36v 250watt rear hub 26" moter wheel 7 speed freewheel 135mm
revs I would think at the lower end (201) bafang 8 fun wheel is from kudos mtb
your old motor is sensorless with internal speed sensor.I have not got the 6 pin lead from moter to controller (think that must have been bined in error)
you can replace the broken pedal sensor with the KT left side sensor.I have the newer kt type left hand pas sensor?
