Cadence Sensor (PAS Sensor)
The Hall effect sensor is responsible for detecting the magnetic pulses generated by the crank's rotation. If the internal circuitry fails or the sensor is mechanically displaced, the controller receives no frequency signal and will not engage the motor. This is the most common point of failure for pedal-assist systems on this specific model.

PAS Magnet Ring
The magnet ring is press-fitted onto the bottom bracket spindle; if the ring becomes cracked, contaminated with metallic debris, or migrates too far along the axis, the magnetic flux will not be sufficient to trigger the Hall effect sensor. This results in an intermittent or total loss of pedal assist while the throttle may still function.

Rad Power Bikes 35A Upgrade Controller
If the sensor and magnet ring are verified to be functional and aligned, the failure likely lies in the controller's logic board. Specifically, the input pin responsible for processing the PAS pulse train or the 5V power supply to the cadence sensor may have suffered a thermal or electrical failure.
