PAS Pedal Assist Sensor, stealth design with 12 Magnets for E-Bikes – Precise, Smooth, and Easy to Install
This pedal assist sensor (PAS) system comes as a one part system. The magnet wheel attaches to the exposed part of the bottom bracket where the crank arm connects. It intersects with the ‘teeth’ of the end of the BB shell. The type of BB needed is shown in the last product picture. As it is a 1 piece design PAS it is far more reliable as you no longer need to be concerned by the distance between the magnet wheel and the sensor.
Featuring 12 magnets on the PAS, this sensor delivers precise pedal detection and reliable performance across a wide range of e-bike systems.
