Triumph-Werke Nürnberg AG or TWN, was a German bicycle and motorcycle company. In 1886, Siegfried Bettmann founded the Triumph bicycle factory in Coventry, England, and in 1896 he founded a second bicycle factory in his native Nuremberg, Germany, under the same Triumph name. Both factories branched out into making motorcycles: the Coventry factory in 1902 and the Nuremberg factory in 1903.

Siegfried Bettmann was a bicycle, motorcycle and car manufacturer and initiator of the Triumph Motorcycle Company. In 1914 he established the Annie Bettmann Foundation to help young people start businesses. Triumph became one of the most famous motorcycle trade-names in the world. Bettmann was also Mayor of Coventry from 1913-1914.
