The Solex motorized bicycle was conceived during World War II and marketed in 1946, with 8 million being sold between 1946 and 1988 in France and internationally, having been marketed in some 70 countries. The French design ceased production in 1988. It lived on for almost two decades as a licensed design produced in China and Hungary. Production returned to France in 2005, and as of 2011 the S4800 model was being marketed by VeloSolex America in North Bergen, New Jersey.
