This peculiar bike, captured by the US Military in 1945, initially resembles an Indian Chief however reveals a novel engineering feat upon nearer inspection.
The Killinger and Freund Motorbike, designed in 1935 by 5 German engineers, sought to modernize the Megola front-wheel-drive bike with improved aerodynamics and effectivity. The three-cylinder two-stroke engine was embedded inside the entrance wheel, streamlining mechanics whereas enhancing efficiency.

The bike’s tubular body, enclosed in sheet metallic, contributed to a smooth, futuristic aesthetic. Its rear suspension featured sturdy rubber and metallic parts that required no servicing, guaranteeing longevity. The modern front-wheel-drive system lowered the engine’s weight whereas integrating a vibration-resistant carburetor for smoother operation.
The Drehschieber rotary valve exactly timed fuel-air consumption, optimizing effectivity and stability throughout all three cranks. A compact two-speed transmission with slope-meshed gears facilitated seamless energy supply. The bike was constructed for simple upkeep, permitting fast entry to very important parts.
Although meant for civilian manufacturing, World Warfare II prematurely halted its improvement, abandoning an excellent however unrealized masterpiece in bike historical past.
