246cc two-strokes designed by Wilhelm Gutbrod who later founded the Standard brand, making Klotz the immediate predecessor of Standard motorcycles.
Ridden by Gebbardt et al, the marque was quite successful in competition.
There are probably seven of the Klotz motorcycles extant. The Bahnhofstrasse factory produced a total of around 150 motorcycles.
The firm also built small trucks with 1 to 1.5 tonne load capacity.
