Bafang BBSHD PAS disc ring

This disk is filled with magnets that send a pulse to the sensor. If the Bafang BBSHD motor no longer assists when pedaling, then it may be due to the PAS disc, the PAS sensor or the controller. This can be determined or narrowed down by using a throttle lever. To replace the pulley, simply remove the housing cover and take out the axle – alternatively, we also have the PAS sensor available.
