The Spanish company SB in 1950 began production of small mopeds with engines of 72 and 86 cm3. The first copies were sold under the brand name David. In 1951, a new model with chain drive and a two-stage gearbox was developed. It is available in versions 76, 86 and 97, which corresponded to the volume of the engine. In 1956, this model evolved into version 75 and 98 with a three-stage gearbox and telescopic rear suspension. Total about 3,000 of mopeds of different models were produced.
