Manufactured by Side Motor Co, 29 Jean Robiestraat, Brussels, 1953-1956
When introduced the machines were powered bicycles with Victoria FM38L clip-on engines mounted to the rear wheel of a bicycle. Later models were mopeds and it is thought that they originated with the German company which produced the enormously popular Vicky mopeds.
