Seigfried Bettmann immigrated to Coventry in 1884 and began manufacturing bicycles in both England and Germany. Shortly after the turn of the century, he turned his attention to motorcycles and these were also made in both countries.

To avoid confusion between the two Triumph companies, the German bikes were ultimately named TWN (Triumph Werkes Nurnberg).


With the advent of the Great Depression, Triumph, now in both the motorcycle and car business, spun off the German subsidiary. It became part of Adler-Triumph, another auto and motorcycle maker. The TWN motorcycle marque lived on until 1957.
