Dunelt Motorcycles was a British motorcycle and bicycle manufacturer. Based in Sheffield, the business was founded by two steel makers and engineers, Dunford and Elliott (Dunelt is a combination of their names) of Sheffield in 1919. Their first motorcycle was an innovative supercharged 499 cc two-stroke single. The company specialised in good quality sidecars from 1926 and a Dunelt motorcycle was first to cross the desert from Cairo to Siwa and back in 1924. Dunelt also enjoyed racing success and won the Double Twelve Hour World Record at Brooklands with a Model K in 1928. Dunelt moved into commercial three-wheeled cars but these were not a success. A Dunelt moped was exhibited at the Earls Court show in 1956 but the company diversified into other areas of engineering in 1957.
