Werner 2 h.p. motor bicycle, 1902-3, with accumulator ignition, spray carburettor. Pedals, crank and chain missing. This model marks a major step in the development of the practical motorcycle. The location of the engine at the bottom bracket of the frame provided the best solution to problems of weight distribution and frame strength. In addition, the engine was actually built in to the frame, rather than simply being clipped on. The engine is a 262 cc, four-stroke unit with an automatic inlet valve and the De Dion-Bouton system of coil ignition. Lubrication is by hand pump. There is no clutch, and pedalling gear would originally have been fitted for starting and for assisting the engine where necessary.
