A World War II US Soldier Posing With Captured Killinger and Freund Motorcycle, 1945
This peculiar motorcycle, captured by the US Army in 1945, initially resembles an Indian Chief but reveals a unique engineering feat upon closer inspection.
The Killinger and Freund Motorcycle, designed in 1935 by five German engineers, sought to modernize the Megola front-wheel-drive motorcycle with improved aerodynamics and efficiency. The three-cylinder two-stroke engine was embedded within the front wheel, streamlining mechanics while enhancing performance.

The bike’s tubular frame, enclosed in sheet metal, contributed to a sleek, futuristic aesthetic. Its rear suspension featured durable rubber and metal components that required no servicing, ensuring longevity. The innovative front-wheel-drive system lowered the engine’s weight while integrating a vibration-resistant carburetor for smoother operation.
The Drehschieber rotary valve precisely timed fuel-air intake, optimizing efficiency and balance across all three cranks. A compact two-speed transmission with slope-meshed gears facilitated seamless power delivery. The motorcycle was built for easy maintenance, allowing quick access to vital components.
Though intended for civilian production, World War II prematurely halted its development, leaving behind a brilliant but unrealized masterpiece in motorcycle history.
