German Motorrad

Ermag Motorcycles

Manufactured by Erlanger Motoren Aktiengesellschaft, Erlangen-Buckenhof (near Nuremburg), 1923-1930

Initially named E.M.A.G., the firm built two-stroke models with rotary valve and stepped pistons, the first of which was a 250cc unit-construction engine designed by Albert Roder, previously of Ziro and who later gained fame working with NSU.

A 500cc sidevalve model appeared in 1928, the U 500. The marque did well in competition, ridden by Perl, Bittorf and Hieronymus.
