The Megola had a unique design: it boasted a Monosoupape rotary engine mounted within the front wheel. The engine contained five cylinders with side-mounted valves and it displaced 640 cc (39 cu in), a total size equivalent to many modern bikes. The crankshaft was the front axle, which remained stationary while the cylinders rotated with the wheel. A hand-controlled butterfly valve was located in the hollow crankshaft to regulate throttle. Power output was a meagre 14 bhp (10 kW) but was applied directly to the wheel. This arrangement produced a very low centre of gravity and provided for excellent handling.
