Two Young Girls Posing On The Old Sidecar

The first mention of a sidecar is in a cartoon by George Moore in the January 7, 1903 issue of the British newspaper "Motor Cycling". Three weeks later a provisional patent was granted to Mr. W. J. Graham of Graham Brothers, Enfield, Middlesex. Early plans to have the sidecar removable have never been very successful. A motorcycle with a sidecar is sometimes called a combination, an outfit, a rig or a hack.
Design
A sidecar motorcycle is a three wheel vehicle with the side wheel not directly aligned with the rear motorcycle wheel, and is usually powered by the rear wheel only. This is different from a motor tricycle (trike), where both rear wheels are powered and share a common axle. However, either P.V. Mokharov of the Soviet Union or H.P. Baughn of Great Britain seem to have to been the first to employ a driven sidecar wheel in 1929. Baughn two-wheel drive outfits were so successful in trials events in the early 1930s that there were attempts to have the ACU ban them from competition. A great many companies experimented with two-wheel drive in sporting events and indeed many companies employed them in military vehicles prior to the commencement of WWII. Currently, the Russian manufacturer Ural produces several models with two-wheel drive that can be engaged as desired.
