A Brief History of the Marque
Manufactured by Aufbau-Industrie Bremen G.m.b.H., 1925-1926
Built under licence from Borgward, the "Blitz-Karren" was a commercial three-wheeled cart driven by a DKW engine, with the driver's seat above the rear wheels. The machine required push-starting, and this did not contribute to its market success.
