A Brief History of the Marque
Manufactured in 1960 by Karl Schlör, Kleinfahrzeugbau, Ludwigsburg, Karlstr. 28, these were 50cc mopeds with JLO and Sachs engines.
Schlör had attracted considerable attention in 1939 when he built a very unusual aerodynamic car, the Schlörwagen. It was far ahead of its time, but was badly damaged during the war and subsequently disappeared.
