This pedal assist sensor (PAS) is designed to equip or replace a sensor on an electric bike. It detects the movement of the bottom bracket and transmits the information to the controller to automatically activate motor assistance.
Thanks to its high-sensitivity magnet system, it offers fast and reliable pedaling detection, enabling smooth and gradual assistance. Compatible with numerous e-bike systems, it is perfectly suited for both conversion kits and repairs.
Easy to install, this sensor mounts directly onto the bottom bracket spindle and adapts to most standard configurations.
