On the basis of their indications, all the necessary changes were made for the definition of the series modelwhich took place on April 12.
To start production, Suzuki decided to rely on various external suppliers, choosing to deal internally only with the engine and the components that gravitated around it. There Power Free immediately showed off the double crown mechanism which allowed it to move indifferently like a muscle bicycle or a motor vehicle. The mechanics were patented, also coupled to an exclusive two-speed transmission system equipped with a multi-plate wet clutch, another unique feature. Thanks to these measures, the Power Free showed performance and ease of driving superior to competitors’ vehicles.
A group of 10 Power Free, led by Shinzo Suzuki and Yoshichica Maruyama participated in the Hamamatsu Festival parade on May 1st, attracting the curiosity of the public that was along the streets. The June 5th the Power Free was exhibited and for the first time put up for sale by reservation in a stand in front of the Chamber of Commerce and Industry in Hamamatsu. The operation was repeated about ten days later at the Shirokiya Department Store, in the Nihombashi district, in Tokyo, and even on that occasion the public was very warmly welcomed. Power Free was sure to become a trend phenomenon, with steadily growing sales, but her career turned out to be quite short.
With the entry into force of an updated Highway Code, in August 1952, there was a push to design engines with larger cubic capacity, more performing and more in line with the demands of the public. The Power Free remained in production for some time, however, leaving the role of flagship of the brand to Diamond Free from 60 cc of 1953, whose sales initially amounted to around 4,000 copies per month to then reach an altitude of 6,000 thanks to the echo of his triumph in the first uphill race held on Mount Fuji, also in 1953.
