Two Young Girls Posing On The Old Sidecar

History
Sidecars have been manufactured since early in the twentieth century. Until the 1950s sidecars were quite popular, providing a cheap alternative to passenger cars; they have also been used by armed forces, police and the UK's AA and RAC motoring organisations. During WWII, German troops used many BMW and Zündapp sidecar motorcycles. On German, French, Belgian, British and Soviet military sidecars, the side wheel was sometimes also driven, sometimes using a differential gear, to improve the vehicle's all-terrain ability.
One of Britain's oldest sidecar manufacturers, Watsonian, was founded in 1912. It is still trading as Watsonian Squire. Jaguar Cars was founded in 1922 as a sidecar manufacturer, the Swallow Sidecar Company.
