These were prosperous years for the British motor-cycle industry, a flourishing proprietary-engine business (led by J.A.P. and Villiers) allowing smaller firms like Coventry-Eagle to concentrate on frame design with their 1926 J.A.P. engined 200 c.c. B33. In the early 1920s belt drive was still in evidence on light weights as typifued by the 1921 2 1/2 h.p. Wooler also used belt drive, though this one has a foot-operated infinitely-variable gear. Chains and multi-speeds, however, featured on even the little 1925 “round tank” 2 1/4 h.p. B.S.A., long the transport of G.P.O. messenger boys.Unit construction of engine and gearbox was gaining hold, on Royal Enfild’s 1919 inline four cylinder prototype, retrieved for exhibition from a forgotten storeroom after 35 years. Sunbeam’s 1925 Light Solo had proper chain cases, and superior finish which justified a price of $88 for a touring 500.
