c.1955 Vincent 48cc Firefly Cyclemotor
Frame no. TM 145
Seeking new products to ease its parlous financial situation, Vincent took over the production of electrical component manufacturer Miller's new cyclemotor in 1953. Known as the Firefly, this 48cc two-stroke unit was designed to fit beneath a bicycle's bottom bracket and drove the rear wheel via a roller. The latter was larger in diameter than many similar devices and was claimed to offered improved traction and reduced tyre wear. Vincent soon offered a complete machine, which featured a lady's-type open frame manufactured for them by Sun, the long-established Birmingham-based manufacturer of bicycles and (later) lightweight Villiers-powered motorcycles. The Firefly outlasted its more famous heavyweight v-twin brethren, remaining in production until 1958.

Fitted to a Sun lady's bicycle, this Firefly must represent by far the cheapest route to Vincent ownership. The machine is un-restored and original, still retaining its factory-applied paint and decals, and even - it is believed - the original tires. Noteworthy features include electric lighting and a luggage carrier at the rear. The vendor advises us that the machine only requires a fresh battery to get running. A rare survivor, and all the more so in this condition.
