Two Young Girls Posing On The Old Sidecar

A sidecar is a one-wheeled device attached to the side of a motorcycle, scooter, or bicycle, producing a three-wheeled vehicle.
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.
