Adler, 1886, Germany, established in Frankfurt/Main in 1886 by Heinrich Kleyer as a bicycle-factory (nearly all motor cycle makes derived from bicycle-factories). The first Adler motor cycle had be created in 1901, at first still with French engines, which had been replaced by their own since 1903. The essential breakthrough succeeded after the Second World War. In the Fifties the Adler models had been very popular for the "Six-days-Trials" ect. But already in 1956, already part of the Grundig-Group, Adler had to get into sales-community with Hercules and Triumph, before its history ended in 1958 definitely.
