See Henri Vallee
The motor was a two-cylinder one, the invention of M. Vallee, and that of vehicle illustrated is of four hP. Four changes of speed are provided by means of gears, and as the speed of the motor can be varied from 200 to 500 revolutions per minute, all speeds between three miles and fifteen miles per hour could be obtained. The engine can be reversed, Electric ignition was used and a carburetter was fitted of special construction, which was maintained at the suitable temperature by the circulation of the exhaust gases. Yje front wheels were fitted with a simple and comfortable spring arrangement, practically similar to that used on the "Rudge" tricycles some nine or ten years prior.
1895 The Vallee was exhibited at the Salon du Cycle in Paris.
