Suzuki's first two-wheeled vehicle was a bicycle fitted with a motor called, the "Power Free." Designed to be inexpensive and simple to build and maintain, the 1952 Power Free had a 36 cc, one horsepower, two-stroke engine.[8] The new double-sprocket gear system enabled the rider to either pedal with the engine assisting, pedal without engine assist, or simply disconnect the pedals and run on engine power alone. The patent office of the new democratic government granted Suzuki a financial subsidy to continue research in motorcycle engineering.
