1910 Bicycle. Seen at the National Cycle Collection. Sparkbrook Cycle Company of Coventry.
1912 Late in the year, this long-established cycle firm entered the powered market with a single sidecar model. It had a 6hp JAP engine, two-speed gearbox, chain-cum-belt drive and Druid forks. The coach-built body was suspended on C-springs.
1914 An 8hp version was added.
1915 Production of the sidecar model stopped, but a light solo was listed and this alone continued into the following year.
1919 Two models appeared, each with the 269cc Villiers engine. One had direct-belt drive, and the other two speeds via their own counter-shaft gearbox with belt final drive.
1921 Those two models continued with the additional option of a two-speed Sturmey-Archer gearbox. During the year a utility-version of the direct-drive two-stroke was added and sold from 1922 to 1923 as the Spark.
The Spark was a very basic utility model fitted with the 269cc Villiers
two-stroke engine and direct-belt drive. It had a simple frame with pressed
sheet-steel lugs and Gosport
front forks. When Villiers
stopped making the older engine, the 247cc unit was used in its place.
1922 The range ran on and was joined by a 346cc sv JAP model.
1923 They changed to the new Villiers 247cc and 343cc engines, kept the 346cc sv JAP and added another model with the 349cc sleeve-valve Barr and Stroud. All models came with a choice of transmissions and speeds, together with complete sidecar combinations with the four-stroke engines.
1924 A 349cc ohv Bradshaw engine replace the JAP, and that, with the others, brought the marque to its close.
1925 Acquired by Singer.
