💡 What is a pedal assist sensor and how does it work in e-bike systems?

Pedal assist sensors translate pedal motion into electrical signals that control how much the motor helps you pedal.

- Detect pedal movement via magnets or Hall-effect sensors - Send pulse signals to the controller to throttle motor output - Proper installation matters; keep a 3-5 mm gap between sensor head and magnet - Works with common e-bike voltages and controllers for steady assist
