The World’s First Production e-Bike

The original Power Assist System (PAS) was composed of a torque sensor that detects the force being applied to the pedals; a speed sensor to detect the speed of the bicycle in motion; a computerised controller coupled to the electric motor that generates assistive force; the drive unit transmitting that assistive force to the rear wheel; and the battery that powers the system. The electric motor provided a supplementary force nearly equal to that put to the pedals by the rider. Once the model was ready and released to the market, it marked the birth of the world’s first e-Bike.
