3.Sidecar
A sidecar is a one-wheeled device attached to the side of a motorcycle, producing a three-wheeled vehicle. Early sidecars were intended to be removable devices that could be detached from the motorcycle. 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. A motorcycle with a sidecar is sometimes called a combination.
