In Roseheim, Germany 1948, Fritz Fend (a former aircraft designer) introduced the Fend Flitzer. The small single-seater 3-wheeler was initially introduced as an invalid car for those disabled as a result of World War II.  The Flitzer was available either in a manually driven version or came powered by a 38cc Victoria  or 98cc Sachs engine and had a steel body. At first the vehicles were fitted with small bicycle wheels but these  were replaced by small scooter wheels. The engine was also later uprated to a 100cc Riedel engine. In 1953 after Fend was approached by Professor Willi Messerschmitt along with his idea for a two seater version the Fend Flitzer was taken over by Messerschmitt and Fend used the Flitzer to form the basis of a two seater version; the Fend Kabinenroller FK 175 (The Messerschmitt 175).

In 2000 Fend created a new prototype vehicle that was a 4-wheeler, though the rear wheels were postioned very close to each other giving the illusion of a 3-wheeler. The vehicle was to be powered by a 650cc BMW engine. Aged 80 years old, Fritz Fend died on 22nd November 2000  bringing an end to the car’s development.
