Solex carburetors were used by many European automotive companies including Rolls-Royce Motors, Land Rover, Mercedes-Benz, Volkswagen, and Porsche, and were also licensed to Japanese maker Mikuni.
Production in Hungary was discontinued in 2002, and then resumed in France in 2005 with a line of gasoline and electric-powered bikes and mopeds being sold, as of 2021, under the VéloSoleX name as part of the EasyBike Group.
Among the European companies which used Solex carburetors were: Rolls-Royce Motors, Alfa Romeo, Bristol, Fiat, Audi, Ford, BMW, Citroën, Opel, Simca, Saab, Singer Motors, Renault, Peugeot, Lancia, Land Rover Series, Lada, Mercedes-Benz, Volvo, Volkswagen, Zündapp and Porsche.

The first prototype of a VéloSoleX was created in 1941 and used regular bicycle frames such as those under the Alcyon brand and were powered by a 45 cc (2.7 cu in) engine developed by Solex.
