PAS V-12 Pedal Assist Sensor with 12 Magnets for E-Bikes – Precise, Smooth, and Easy to Install
This pedal assist sensor (PAS) system comes in two parts. The magnet wheel attaches to the exposed part of the bottom bracket where the crank arm connects, while the sensor mounts securely on the bike’s seat tube. As the magnet wheel passes close to the sensor, it sends signals to the controller to provide smooth motor assistance, ensuring a natural pedal feel.
Featuring 12 magnets on the disc, this PAS sensor delivers precise pedal detection and reliable performance across a wide range of e-bike systems.
