Two Young Girls Posing On The Old Sidecar

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.
The sidecar consists of a frame (which originally was rigidly fixed to the motorcycle's frame on one side and is supported by the sidecar's wheel on the other side) and of a body. The body typically provides one passenger seat and a small trunk compartment behind. In some case the sidecar has a removable soft top. In some modifications the sidecar's body is used for carrying cargo or tools (like a truck's platform). The sidecar is typically mounted so that the motorcycle is closer to the center of the road (sidecar on the right for right-hand traffic.)
