McEvoy Motorcycles

McEvoy Motorcycles was a British motorcycle manufacturer based in Derby. The company used engines from Villiers, Blackburne, British Anzani and JAP. The company ceased trading in 1929 when the financier Cecil 'Archie' Birkin was killed in an accident at the Isle of Man TT.
History.
Eton College graduate Michael McEvoy began his engineering career at the Rolls-Royce factory in Derby and started McEvoy Motorcycles in 1924. The first bike from McEvoy Motorcycles was a flat twin produced in 1925 with a British Anzani 1100 cc engine. By 1926 the business was successful enough for McEvoy to leave his job at Rolls-Royce and move to larger premises in Derby. The McEvoy range was developed to include a JAP8/45 hp engined V-twin in an advanced "super sports" frame that was capable of and advertised by McEvoy as "the Fastest all-British big twin that holds all high speed British records worth holding in its class".
McEvoy began producing motorcycles with a range of engines, including one with a small 172 cc Villiers engine. All was going well until the company's financial backer, Archie Birkin, died practising for the 1928 Isle of Man TT; the company was wound up in 1929.

Patchett also rode Anzani and JAP-powered V-twin to successes at the banked Brooklands Circuit at Weybridge. In his time with McEvoy Patchett set nine world records and won the Championship of Southport in 1926 at more than .
