The story
The first bike from Montgomery Motorcycles was a flat twin produced in 1913 with a Morton and Weaver engine. The First World War halted production, which did not resume until 1922 in Coventry. William Montgomery continued to experiment with sidecar design and actually competed himself in the 1923 Isle of Man TT sidecar race. The entire Montgomery works was destroyed by fire in 1925 but were able to eventually recover and by 1930 were a leading producer of quality two-stroke and four-stroke motorcycles. The top of the range was the Greyhound, finished in a special grey enamel paint. The Second World War brought an end to all production and Montgomery ceased trading in 1939.Andrew Montgomery now owns the trademark for Montgomery and Montgomery Motorcycles
