King were motorcycles produced from 1901 to 1905 in Cambridge.
1901 The firm started out by producing tricycles but soon moved to motorcycles.
1903 They produced a model that was a typical primitive. It had a 2.75hp MMC engine mounted vertically, driving the rear wheel by belt. They also offered the option of 3.5hp or 4hp water-cooled engines.
1904 The engines for that year were 2.75hp to 3.5hp from either DAW or MMC. Direct-belt drive or two speed and chain were available, and a forecar was listed.
1905 The company was short lived and nothing further was heard of it after that year.
