A Brief History of the Marque
1919-1920. Based at Rue de Ridder in Paris, the firm of Charles Combes built a cycle attachment engine, an OHV four-stroke of 118cc and later 143cc, which was integral with a rear wheel which replaced the original. The kit included a 3 litre oil & fuel tank. An example of the motorwheel was part of the famed Guélon Collection.
Lumen also built a complete scooter using the same system. It had floorpan, a wicker seat and rather long handlebars.
Scooters were represented only by the Lumen, a neat little power unit which is made in a form applicable to attachment to pedal cycles.
A small overhead valve motor of 55 X 50 mm. is attached to the rear forks in such a manner that the crankshaft passes through the hub, the flywheel being on the opposite side to the engine. The drive is through an epicyclic gear.
A circular magneto is used for ignition purposes, and in the case of the cycle attachment, both oil and petrol tank form part of the rear mudguard.
