The high quality of the Suzuki’s cycle motor made it to stand out and made it a big hit in Japan. Many of Shunzo Suzuki's original ideas were used on the final product.The engine was a "square" 36 x 36 mm piston-ported two-stroke mounted within the cycle frame, just above the pedals. It powered the cycle through the normal pedaling chain and required special chain-wheels to enable the rider to free-wheel while the engine was running. The engine could also be pedal-assisted, or disconnected completely.The system was so ingenious, the Patent Office of the new democratic government granted Suzuki a financial subsidy to continue research into motorcycle engineering.Unlike most of its competitors, the Power Free did not use army surplus or proprietary engines and was built entirely by Suzuki. Suzuki manufactured even the carburetor and flywheel magneto.The Power Free, launched in late '51, was only on sale for a few months before it was substantially improved. Just after the release of the Power Free the Japanese government changed the requirements to be allowed to ride a small motorcycle. No driver's license were longer needed to ride a bike with an 4-stroke engine up to 90cc or a 2-stroke engine up to 60cc. Suzuki started immediately to develop a new cycle motor which engine capacity was increased to 60cc. and a two-speed gear was incorporated.
