Duo (United Kingdom) - AllCarIndex

Duo was a British automobile manufacturer that operated briefly from 1912 to 1914, based in Deptford, London. The company initially began as Duocars Ltd and later rebranded to Duo Cyclecars Ltd. During its short existence, Duo produced a range of cyclecars that gained popularity for their diverse engine options.

The Duo cyclecars were equipped with several engine choices, including a 6/8 horsepower single-cylinder engine from Buckingham, an 8 horsepower air-cooled V-twin from J.A.P., and 10 horsepower engines from Dorman, Chapuis Dornier, or Mathis. The original model featured a J.A.P. engine and was notable for its armored body design. In 1914, the company announced plans for additional models, including the DE P light car, which was developed by L.F. de Peyrecave after he left Duo at the end of 1914.

Duo's production included innovative features such as a two-speed transmission and belt final drive, with shaft drive utilized in the four-cylinder models. Despite its brief operation, Duo contributed to the early automotive landscape in the United Kingdom before ceasing production.
