Ride Smarter, Not Harder

One of the best features of an electric cycle is the Pedal Assist System (PAS). Unlike a throttle where you just twist and go, PAS senses your pedaling and kicks in the motor to help you.

How it Works

A magnetic ring attached to your pedal crank communicates with a sensor. When you start pedaling, the controller sends power to the motor.

Single Level vs 5-Level PAS

  • Single Level PAS: Provides a consistent boost whenever you pedal. Simple and effective for basic commuting.
  • 5-Level PAS: The game changer. It connects to an LCD display allowing you to choose how much help you want (Level 1 for a little push, Level 5 for maximum speed). This is great for managing battery life.

Frequently Asked Questions

How does a 12-magnet cadence PAS sensor work?

Magnets pass a Hall sensor as you pedal, signaling the controller to deliver proportional motor assistance automatically.

How much extra battery range does riding on PAS provide vs Throttle?

Pedal Assist mode extends range by 35% to 50% by combining human leg effort with motor torque.

How do I clean and align a loose PAS sensor disc?

Ensure the magnet disc sits 2-3mm from the sensor bracket on the bottom bracket spindle and is free of mud buildup.
