VéloSoleX is a moped, or motorised bicycle, usually just referred to as 'Solex', which was originally produced by the French manufacturer Solex, based in Courbevoie near Paris, France. The company manufactured centrifugal fans for car radiators, carburetors, and micrometers before branching into assist motors and bicycles. The moped, originally created during World War II and mass-produced between 1946 and 1988, came in various iterations, while keeping the same concept of a motor with a roller resting on the front wheel of a bicycle.
