Yamaha PWseries C2 Drive Unit: Revolutionizing Urban E-Biking


Yamaha Motor Company, a legendary name in the world of motorcycles and scooters, has consistently pushed the boundaries of innovation since its inception in 1955.

With an unrelenting commitment to exploring new ideas and technologies, Yamaha has ventured into the realm of electric bicycles, and their latest creation, the Yamaha PWseries C2 drive unit, is set to redefine urban and commuter e-biking.

A Legacy of Innovation

Yamaha’s journey into the world of electric bicycles began in the early 1990s with the development of the Power Assist System (PAS) for bicycles.

This groundbreaking system featured an electric motor that provided assistance to the rider’s pedaling input, making it the world’s first production e-bike in 1993. This pioneering spirit laid the foundation for Yamaha’s foray into electric mobility.

The Evolution of Yamaha Drive Units

Over the last three decades, Yamaha has cultivated a stellar reputation for its compact and lightweight high-torque drive units.
