The triple sensor system

2. The triple sensor system

The "triple sensor" system is what holds the product concept of "smooth and powerful" in place. The three sensors are the: 1. a torque sensor that detects pedaling power, 2. a speed sensor that detects the bicycle's speed, and 3. a crank sensor that detects the number of rotations through pedaling. By equipping the three sensors to the unit, the rider is supported by continuous assistance under every riding condition. The constant assist is what allows the "smooth and powerful" concept to come alive during the ride. ...read more

Smooth and Powerful

The overall concept for the PWseries is "smooth and powerful". While providing the smooth electric-assist expected by many general e-Bike users, our systems are equipped with powerful support and a natural, "organic" assist feel in the high speed range as well. The "triple sensor system" is what enables this "organic assist feel" that has been part of Yamaha's development philosophy from the start.
The three sensors refer to: 1. a torque sensor that detects pedaling power, 2. a speed sensor that detects the bicycle's speed, and 3. a 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, allowing for a smooth and powerful assist.
One aim of the PWseries is to win over the hearts of athletic, sporty cyclists, in addition to the every-day users.
