This pedal assist sensor (PAS) is designed to be installed on or replace an existing sensor on an electric bike. It detects the movement of the crankset and transmits the information to the controller to automatically activate the motor assist.
Thanks to its highly sensitive magnetic system, it provides fast and reliable pedaling detection, enabling smooth and progressive assistance. Compatible with many e-bike systems, it is ideal for both conversion kits and repairs.
Easy to install, this sensor mounts directly onto the bottom bracket shaft and fits most standard configurations.
