Rieju is a manufacturer of mopeds and motorcycles from Spain. In 1934, two young entrepreneurs, Luis Riera Carré and Jaime Juanola Farrés, founded a company to manufacture bicycle accessories. The name RIEJU came from the first letters of each of their surnames (RIEra + JUanola). 2011 sees the launch of many new Rieju machines, most notably the new RS3 50 and RS3 125LC. They are made in Spain and are powered by Yamaha engines.
