Duzmo Motorcycles was a British motorcycle manufacturer. Founded in Enfield Highway, London in 1919 by John Wallace, engines for the early Duzmo machines were manufactured by the Advance Motor Manufacturing Company in Northampton. Wallace had no training as an engineer but while he was still at school he set up a workshop in his garden and built a motorcycle from parts. This experience helped him secure an apprenticeship with Collier & Sons. His father bought him a Rudge racing motorcycle and he began competing at Brooklands. [1] Originally riding for JAP until they found he was under age, Wallace met Bert le Vack and both found work at Scottish car makers Arrol-Johnston designing aircraft engines for the duration of the First World War.
A motorcycle, often called a bike, motorbike, or cycle, is a two- or three-wheeled motor vehicle. Motorcycle design varies greatly to suit a range of different purposes: long distance travel, commuting, cruising, sport including racing, and off-road riding. Motorcycling is riding a motorcycle and related social activity such as joining a motorcycle club and attending motorcycle rallies.
Enfield Highway is an area in the London Borough of Enfield, north London. It is roughly located in the area either side of Hertford Road between Hoe Lane and The Ride.
The Advance Motor Manufacturing Company was a British motorcycle and engine manufacturer established in 1905. As well as supplying aircraft engines to the pioneering monoplane developers, Advance engines were also used by Captain Robert Scott to power Antarctic snow sleds. After the end of the Second World War the company was sold to Sheepbridge Engineering and became a motor supplies organisation.
After the war Wallace designed a racing motorcycle engine and sold the design to the Portable Tool and Engineering Company of Enfield Highway, who employed Wallace as their chief designer. Bert le Vack helped with development and between them created the Duzmo in 1920. They were keen to go into production but the Portable Tool directors decided to wind up the company. Wallace borrowed money to go it alone and built Duzmo motorcycles under his own name, with engines made for him by The Advance Motor Manufacturing Co. of Northampton. [1]
Northampton is a large market town and the county town of Northamptonshire in the East Midlands of England. It lies on the River Nene, 60 miles (97 km) north-west of London and 45 miles (72 km) south-east of Birmingham. One of the largest towns in England, it had a population of 212,100 at the 2011 census.
Wallace designed the last Duzmo in 1923. It had a number of novel innovations, including an inclined engine and low seat but only one was built before Wallace ran out of money and had to sell the business to D. J. Sheppards. He returned to aircraft engine design with D. Napier & Sons and died in 1983. [1]

By 1920 they were seeing success in racing at the Isle of man TT and Brooklands. In 1927, Bert Le Vack took over racing development and was the first rider to complete a lap at over 100 mph on a 500cc machine at Brooklands. They began to manufacture their own Single valve and OHV single cylinder engines and produced a 212cc two stroke motorcycles using a Levis engine. Times became tough for Patterson after 1 of his sons died in WW1 and the other had lost a leg. The family sold the factory to HJ Bructon after WW1. New Hudson also produced 3 wheelers using MAG engines. New Hudson was taken over by BSA cycles in the late 20’s and by 1933 had ceased all production of motorcycles. In 1929 the company purchased the Girling brake patent from the inventor Albert Girling, to supply brake systems to Ford, Austin, Rover and Riley.

The term was coined by a magazine road tester in his review of the bike, and Brough eventually obtained explicit permission to use it after a Rolls-Royce executive toured the Brough Superior factory. All bikes had a guarantee that they were capable of 100 mph (160 km/h).
