Made between 1918 and 1937 by the Co-operative Wholesale Society (CWS) at Tyseley, Birmingham using four-stroke JAP and two-stroke Villiers engines
1921 They started out by providing reliable transport for the thousands of commuters who regularly shopped at the Co-operative Wholesale Society. The machines could be ordered from any one of their numerous outlets throughout the UK. The first motorcycles had a 292cc sv JAP single. This drove a belt to the rear wheel through a two-speed Sturmey-Archer gearbox. Fitted with Brampton Biflex forks, it had a choice of touring or TT type handlebars. Although they were not built with sport in mind, Federation's won fourteen class awards in their first season.
1922 A 677cc sv V-twin JAP model was added.
1923 They built a motorized bicycles that was fitted with a 147cc Villiers engine. For a short time that year there was also a three-wheeler, but it was the motorcycles with JAP engines, and later Burman gearboxes, that were a real success.
1929 Until now, side valves had always been used, but that year the firm introduced a 346cc ohv model and saddle-tank styling.
1930 A sv 500cc model was added.
1931 That was followed by one of 677cc and an ohv 500cc version.
1933 By now only one of the four-stroke was available, but that was soon joined by a 245cc ohv model and a couple of 150cc versions with Villiers engines.
1937 The Co-operative Wholesale Society stopped producing motorcycles in order to concentrate on groceries.
Most of the surviving Federation models (fifteen) are held in one private collection in the UK.
