Sheffield-Henderson were motorcycles produced in Fitzwilliam Street, Sheffield from 1920 to 1923.
Henderson sidecars were made by the Aero works of Fitzwilliam Street.
1920 Having previously been well-known for the production of sidecars, the company moved into motorcycle manufacture with a 3hp two-stroke model with their own engine and two-speed chain-cum-belt transmission. It introduced their own design of front fork, with C-spring linking the double tubed girder to the frame head. By late in the year, a 499cc sv Blackburne model had been added, with a three-speed Sturmey-Archer gearbox and all-chain drive and vacuum-operated oiling system for the engine. It was ideally suited to sidecar usage. In a relatively short time the make gained a fantastic reputation in speed events. The machine could be had with a side valve or overhead valve Blackburne engine or a Bradshaw engine. The machine had a three-speed Burman gearbox.
1921 A new model was tried, fitted with the 348cc ohv Blackburne engine.
1922 That new model was catalogued and sold with a guarantee of 70mph (112km/h). There was also a sporting sidecar outfit with a tuned 545cc sv Blackburne engine and streamlined sidecar. In June, the factory even claimed several world records in the 250cc class. Sheffied Henderson must have been one of the very few makes that placed the toolbox under the top tube behind the steering head, a position that obviated a rather unusual tank shape, an early form of saddle tank.
1923 The marque did not survive beyond the end of the year.
1921 Olympia Show
In addition to a range of Henderson sidecars for which this Sheffield firm is now well known, two new models of the Sheffield- Henderson motor cycle will be exhibited; one of these will be engiued with the 2¾ h.p. o.h.v. Blackburne engine, and having a frame of rather unique design, which gives an exceptionally low riding position.
This new mount, which is to be sold purely as a sports model, will carry with it a guarantee of 70 m.p.h. A Sturmey-Archer three- speed gear with close ratios and without kick-starter, forms part of its equipment.
The other model is a dual purpose machine having the new 4¼ h.p. Blackburne engine of 550 c.c, Sturmey-Archer three-speed gear, and other first-class equipment. The vacuum lubrication system on this machine is somewhat unique.
