This pedal-assist sensor (PAS) is designed to be fitted to or replace a sensor on an e-bike. It detects the movement of the crankset and transmits the information to the controller to automatically activate the motor assistance.
Thanks to its highly sensitive magnet system, it offers fast and reliable pedalling 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 spindle and fits most standard configurations.
