After having been turned over to weapons production for World
War I, BSA returned to producing motorcycles again which were sold as affordable
with reasonable performance for the average user. BSA stressed the reliability
of their machines, the availability of spares and dealer support. The BSA Model
E was the first of a series of successful V-twins based around the reliable
770cc side valve engine with cylinders at an angle of 50 degrees. The modest 6hp
produced by the engine was able to provide a top speed of 55mph and it had BSA's
own design of three speed gearbox with the drive chain enclosed in an aluminium
casing. There was an increased demand for affordable transport after the end of
the war and the Model E became popular with BSA's matching green and cream
painted sidecar option.
Designed for easy servicing the valves were interchangeable
and had quickly adjustable tappets. The constant loss oil pump was supplemented
by a hand operated pump and the wheels were also quickly detachable and the same
size so that they were interchangeable.
Although the BSA Model E was produced until 1924 it had been
largely replaced by the more powerful 986cc Model F in 1922, which continued in
production as the BSA Model G, with continual modifications, until just after
the outbreak of World War II.
Between 1920 and 1925 BSA produced a 100 small three-wheeled
taxi cabs using the Model E 770cc V twin engine.
