A bubble of post-war ingenuity. 🚘 The Messerschmitt Kabinenroller is one of the most fascinating microcars ever built — a three-wheeled, tandem-seat design inspired by aircraft engineering and created by German designer Fritz Fend. First introduced in 1953 with the KR 175, and later evolved into the KR 200, this tiny machine offered a surprisingly aerodynamic body, a distinctive plexiglass canopy, and clever engineering that allowed the motor to run in reverse for backward travel at full speed.
