BAFANG SHIFT SENSOR
These sensors are fitted inline with the gear cable & cut the power to the motor temporarily to allow smoother gear changes & reduces the load on the chain & cassette.
If you ride normally in the lower power settings & your gears are adjusted correctly then they aren’t essential but if you intend changing gear under higher loads or while using the throttle then they are recommended
