 The BAC was designed in 1925 by an aircraft engineer of the Peugeot company with advice from the legendary motorcycle pacer Arthur Pasquier. Louis Bac built about 50 machines to this design, for use at cycling tracks.
(to entlarge the pictures click in the image) The machine has neither clutch nor gears, the transmission is effected by a 10 cm wide belt. The diameter of the rear wheel pulley has been fixed by regulations to 50cm, the engine pulley diameter can be chosen to suit specific circuit conditions. Between 1932 and 1938 an improved version of the BAC was produced in France, called the Eyer. About 30 of these Eyer BACs have been built; the machine on offer is one of that batch.
The main improvement in the Eyer design is the application of a dry sump lubrication system, which significantly enhances the cooling and lubrication. These antique looking giants have been used on cycle tracks till relatively recently because it was very difficult to find modern machines that could match their enormous flexibility :without clutch or gears a Eyer BAC could accelerate very steadily without jerking from almost walking speed to more than a hundred kilometres per hour. This Eyer BAC is in unrestored condition. The Beijing Company Hua De Feng Ying offers this vehicle for sale. Complete details can be found on their webpage www.elomnibus.com .
