BGA is the brand of Établissements Blanchard-Grange, a manufacturer of guns, bicycles and mopeds based in St-Étienne.

The business was possibly established by Claudius Blanchard and a Monsieur Grange in 1900. In 1935 Claudius Blanchard developed, and patented, the BGA Velectrik derailleur. In the 1950s he diversified into mopeds and in 1958 he died and his son Claude Denis Blanchard took over the business.

In 1976 the company was called Blanchard et Cie when it re-registered ‘BGA’ as a trademark. Finally there is apparently an even more recent record that in 1984 the business was managed by one Jean Michel Barrière and employed 10 people making bicycles.
