The Messerschmitt Kabinenroller (cabin scooter) was designed by Fritz Fend, who had his own company from 1948 to 1951. The 3-wheel KR 175 was introduced in 1953 and continued until 1956. Fritz Fend then bought the project from Messerschmitt and cars were then re-named FMR (Fahrzeug und Maschinenbau GmbH Regensburg), production ending in 1964.
