A 1920
BSA 6/7 h.p. Model E v-twin with a Taxi Sidecar sold recently for
£24,725, equivalent to $NZ 53,402. The
Bonham's auction was held at the National Motor Museum, Beaulieu. The
motorcycle was first registered on 28th January 1921, and was one of 19
motorcycle taxis carrying passengers in Birmingham for the Hackney
Carriage Authority. The 770cc Model E came out late in 1919 and was the
first in a successful line of sidecar tugs. Development began six years
before but was interrupted by the Great War. The valves, which were
interchangeable, were made of high temperature nickel alloy steel which
made them less prone to breakage. Both chains were enclosed in cast
aluminium cases, with BSA's special shock absorber on the engine shaft.
The total loss oil system used a mechanical pump but for motorcyclists
not used to such new fangled devices there was a supplementary hand
pump. As a solo machine the top speed was a modest 55mph but it was
reliability that BSA emphasised.
