Industrias Reyac Aralar, founded by brothers Ignacio and FermÃn Orbaiceta in Pamplona, built mopeds of this name under licence (as stated in the logo on the chainguard) to the parent company SER of France with engines of 49cc and 63cc from 1956 to 1962. They were widely distributed by the Finanzauto network of Madrid, who in 1957 advertised "Ser y Lanch 47cc 74,9cc" along with three other brands.
Manufacture of the Ser engines in France ceased in 1958, but the Spanish engines continued for another four years.
Spanish regulations changed in 1962 making the production of the machines unviable, so the firm switched to household appliances.
According to OTTW, prior to 1956 the Pamplona firm built Lanch mopeds and Ziraco engines.
