Fritz Fend

After the Second World War, Fend, who had been a technical officer with the Luftwaffe, opened a workshop in Rosenheim, Germany.

Fend later made a version that was powered by a 38 cc (2.3 cu in) Victoria two-stroke engine.

[3] However, the KR175's excellent road manners and relative lack of width made it a good city commuter.

Apart from a larger engine, the KR175 was almost completely re-engineered to produce the Kr200,new suspension(introducing shock absorbers to the design), new floor construction,improved engine mounting, larger tires, improved controls, and a means by which to reverse the car.

[6] Production of the KR200 was heavily reduced in 1962 and ceased in 1964[2] In 1956, Messerschmitt was allowed to manufacture aircraft again and lost interest in Fend's microcars.

Messerschmitt sold the Regenburg works to Fend, who, with brake and hub supplier Valentin Knott, formed Fahrzeug- und Maschinenbau GmbH, Regensburg (FMR) to continue production of the KR200 and his other vehicles.

The front suspension, monocoque, and bodywork ahead of the rear sub-frame were derived from the KR200, but the rear sub-frame bore a newly designed suspension and drivetrain with twice the number of wheels and an engine with twice the number of cylinders and more than twice the displacement.

He invented an alarm that went on if the key was removed from a car ignition while the lights were still on, a feature that became popular after his patent ran out.
