"clip on" engined bicycle built from 1953 to 1955 under licence from Miller, who were suppliers of electrical components to Vincent. It was also known as the Vincent Power Cycle. By 1954, Vincent Motorcycles was in an increasingly difficult situation. In the quest for solvency, Vincent looked for ways to improve their position. The trike idea was revived. In 1932 "The Vincent Bantam" was first introduced: Vincent's first 3-wheeler, powered by a 293 cc SV JAP or 250 cc Villiers engine, was a 2.5 cwt delivery van which used a car seat and steering wheel rather than the standard motorcycle saddle and handlebars. The Bantam was priced at £57-10-0 with a windscreen and hood available for an additional £5-10-0. It ceased production in 1936 – the first year of the Series A motorcycle. In 1954/1955, due to falling sales of motorcycles, the prototype 3-wheeler powered by a Vincent Rapide 998 cc engine was produced. Some years later, the vehicle was named "Polyphemus" by its owner, Roy Harper. To keep development and production costs low, it used a parts-bin approach, including pieces from Vincent motorcycles, as well as wheels which came from a Morris Minor. The body was made from 16-gauge aluminium. With the standard Rapide engine, "Polyphemus" could reach . Before it was sold, in the hands of Ted Davis, it achieved with a Black Lightning engine. The "Vincent 3-wheeler" was eventually sold to a member of the public for £500 – a high price for any vehicle at the time, especially for a vehicle with no reverse gear, self-starter or hood. The BMC Mini launched four years later at a price of £497. Unfortunately Vincent motorcycles were hand-built and expensive – only a total of 11,000 machines were sold post–World War Two. A sales slump in 1954 forced the company to import and sell NSU mopeds. One hundred and sixty two-stroke Foxes NSU-Vincent 123 cc were built. There were also 40 98cc OHV four-stroke NSU-Vincents, and Vincent also sold the "NSU Quickly" moped; too well it appears (selling about 20,000 in one year – a footnote to how the market had changed again), as NSU took control of its own sales after a year. Vincent Picador In an attempt to diversify the company, Phil Vincent undertook development of a version of the motorcycle V-twin for aircraft applications. Development of this engine, named Picador, began in 1951 and continued until
