Check out the unusual construction of this French Elfe Cycle Car. It is based on a sheet-metal chassis with a cable-operated pivoting front axle sprung by coil springs. The rear axle is located by links and sprung with cantilever springs. The 20-degree Anzani air-cooled engine is cooled by a belt-driven fan.
