Centre Mount System

The Yamaha Power Assist System employs a center mount system in which the power unit and battery are mounted close to the pedals to create a low center of gravity. This results in outstanding weight balance and excellent running stability.

The triple sensor system

The triple sensor system anchors the product concept of “Smooth and Powerful”. The three sensors are a torque sensor that detects pedaling power, a speed sensor that detects the bicycle’s speed, and a crank sensor that detects the number of rotations through pedaling. Thanks to these three sensors, the system is able to offer the rider continuous assistance under all riding conditions. This constant assist makes the “Smooth and Powerful” concept come alive during rides.
