What is a Pedal Assist System (PAS)?
Electrical bikes use a pedal assist system (PAS) to provide additional power to the rider when pedaling.
PAS typically involves a torque sensor, the motor, and the battery. A control unit manages the power flow between these components.
A torque sensor measures the rider’s pedaling force and sends the measurements to the motor controller. The controller then uses the information to control how much assistance the rider needs from the motor.
The result is a riding experience where the rider feels as if they are being helped along by the electric motor. Since the signal is constantly being measured, and the assistance adjusted according to the signal, the rider will not feel any unnatural push.
This is the opposite of a throttle which you will find on electric scooters and some e-bikes. A throttle will automatically provide the rider with assistance when activated, but it will not correspond with the effort the rider is pushing the pedals.
The assistance from the motor will make it easier to pedal up hills or cover longer distances. PAS systems can vary in complexity, but the basic principle is the same: to provide additional power to the rider to make cycling easier and more enjoyable.
