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 moped originally created during World War II and mass-produced between 1946 and 1988 came in various iterations, whilst keeping the same concept of a motor with roller resting on the front wheel of a bicycle.

Owned successively by Dassault, Renault, Motobécane/MBK, VéloSoleX sold more than 7 million units worldwide before ceasing production in France in 1988.

Primo Levi, in one of the autobiographic short stories in his collection The Periodic Table, mentions that he would be able switch from a bicycle to a VéloSoleX if he managed to conclude a business deal with a cosmetics manufacturer.

In the 1975 Sydney Pollack thriller Three Days of the Condor, Robert Redford rides a Solex to work in New York which sets his character as an unassuming intellectual.
