Excelsior (Coventry)

Excelsior, based in Coventry, was a British bicycle, motorcycle and car maker. They were Britain’s first motorcycle manufacturer, starting production of their own ‘motor-bicycle’ in 1896. Initially they had premises at Lower Ford Street, Coventry, and 287-295 Stoney Stanton Road, Hillfields, Coventry, Warwickshire before moving to Kings Road, Tyseley, Birmingham in 1921.

Originally a bicycle company making penny-farthings in 1874 under their original name: Bayliss, Thomas and Co, they later sold bicycles under the names of Excelsior and Eureka and changed the company name to Excelsior Motor Co. in 1910. In the early years of motor-bicycle manufacture they used Minerva, De Dion, MMC and possibly a Condor 850 cc single but went on to produce a wide range of machines with engines from most major manufacturers. In 1914, they offered a JAP-powered twin. A deal to supply the Russian Imperial government with motorcycles ended with the Revolution and Excelsior wound up with an excess inventory as a result.

The Walker family (father Reginald and son Eric) took over after World War I. R Walker & Sons of Tyseley, Birmingham had started as makers of ships lamps but in 1919 had made a range of motorcycles under the Monarch name to be sold by the London Department store Gamages. The company was re-registered as the Excelsior Motor Company Ltd, production moved to Birmingham and the Lower Ford Street factory in Coventry sold to Francis-Barnett. They made a range of motorcycles from 98 to 1,000 cc, mostly powered by JAP, Blackburne and Villiers engines, plus an 850 cc Condor engine. The new company put more effort in competition and racing. To avoid confusion with the American maker of the same name, they called themselves the "British Excelsior".

Their first major racing success was in 1929 when they took the Lightweight TT race on a B14, soon to be their most popular model. Emerged from the Great Depression in a sound financial state, Excelsior commissioned Blackburne to design a 4-valve racing engine. Known as the Mechanical Marvel, it won the 1933 TT in its first outing. The complex machine continued with great success on the Continent but was retired at the end of the 1934 season as it was too complex to offer for sale as a production racer. That role was filled from 1935 by the 2-valve overhead camshaft Manxman.
