Introduction
Pedal assist (PAS) is the most common e-bike system in the UK. It gives you a boost while you pedal, making cycling easier and more enjoyable.
How Pedal Assist Works
Motor engages only when you pedal. Torque sensors: more pedal effort = more motor assist. Cadence sensors: motor assists at a fixed level when pedaling.
Benefits
Maintains legal compliance in the UK. Extends battery range. Provides gentle exercise. Makes hills and long rides manageable.
