PAS Hall Sensor + PAS PCB Module Replacement for BAFANG BBS02B middrive motor Key benefits Restores correct pedal-assist operation by accurately detecting magnetic fields, preventing intermittent or no-assist issues. Replaces the PAS module and PCB used by the speed sensor module to re-establish precise speed measurement and consistent power assistance. Designed specifically for the BAFANG BBS02B middrive motor to provide compatible and stable control functions. Improves ride quality by restoring smooth, predictable assist response and helping the motor apply power at the intended times. What this part does PAS Hall Sensor: Detects pedal rotation via magnetic field changes so the motor control knows when and how much to assist. PAS PCB board: Interfaces the sensor signals with the motor controller and speed sensor module, enabling accurate speed calculation and coordinated assistance. Why customers need it Fixes common faults such as no PAS response, erratic assist engagement, or incorrect speed readings caused by a failed sensor or PCB. Offers a targeted repair option that can be faster and less expensive than replacing the whole motor or controller. Helps maintain safety and predictability of the bike’s assist behavior, especially on variable terrain. Compatibility and function Specifically intended for use with BAFANG BBS02B middrive motor systems. Functions as the replacement PAS module/controller board and the PAS PCB required by the speed sensor module. Retains original intended functions: magnetic field detection for pedal-assist and signal processing for speed/assist coordination. Performance and reliability Designed to provide accurate detection of pedaling and stable signal transfer to the motor controller, supporting consistent assist levels. Restores efficient power assistance by enabling precise speed measurement and proper timing of motor output. Practical attributes Function: PAS Hall Sensor (magnetic detection) and PAS PCB (signal processing for speed sensor module). Compatibility: BAFANG BBS02B middrive motor. Performance: Intended to restore original assist responsiveness and speed sensing accuracy. Typical use scenarios Repair: Replace a failed PAS Hall Sensor or PAS PCB to stop intermittent assist or a complete loss of pedal assist on a BAFANG BBS02B-equipped e-bike. Upgrade/Refresh: Swap in a new PAS module/PCB during a motor service or refurbishment to restore original responsiveness and eliminate aging sensor issues. Troubleshooting: Use as a verified replacement part when diagnosing erratic speed readings or inconsistent assist, isolating the problem to the PAS assembly. Notes for buyers This product is the PAS Hall Sensor and PAS PCB module replacement designed for the BAFANG BBS02B middrive motor. Confirm that your motor model is BBS02B before ordering.
