Yamaha Triple Sensor System

The key to Yamaha's smooth and powerful assist is our "triple sensor system." The three sensors are:
1. Torque sensor that detects pedaling power,
2. Speed sensor that detects the bicycle's speed, and
3. Crank sensor that detects the number of rotations through pedaling.
The sensors instantly detect the running conditions and the movement of the rider with precision, delivering smooth and powerful assist.



Drive Units

Yamaha Power Assist Bicycles offers two center mount drive units: the PWSeries SE and PW-X.

Integrated with a faster speed sensor as part of the rear hub to increase motor response, giving a natural, organic assist feel. And increased cadence support from 100 rpm to a faster 110 rpm.
