E-Bike Pedal Assist Sensors

E-Bike Pedal Assist Sensors

E-bike pedal assist sensors (PAS) detect when the rider is pedalling and send a signal to the motor controller to activate the electric motor. This system allows the motor to provide assistance only when the rider pedals, creating a smooth and natural riding experience.

Pedal assist sensors are a key component of most electric bike conversion kits and eBike systems. They monitor the rotation of the crank using magnets and trigger the motor when pedalling begins.

Most electric bike pedal assist sensors use a cadence based system where a magnetic disc rotates with the crank and sends signals to the controller.

Our range of e-bike pedal assist sensors includes sensors with different magnet counts, such as 10 magnet and 14 magnet PAS sensors, designed to provide reliable detection and smooth motor engagement.

These sensors are commonly used on hub motor conversion kits and electric bikes, helping riders enjoy consistent pedal assisted power.
