The choice of belt or chain drive was offered to customers, and the range comprised a 2¼ hp single and a 4hp V-twin, plus a forecar.

The engine drives either by belting (Lincona) or by chain gear. This firm is also showing a twin engine of 4 h.p., fitted vertically in a similar manner to the single engine, with the advantage of its occupying no more space than the single type. It also shows an expanding form of a motor pulley of the V type. By pressing together of the sides of the V the belt is forced outwards, thus giving an increased speed of some 25 per cent. as a maximum; it also gives a free engine. In the chain-driven type a spring compensating wheel is used to take up the jar of starting and a friction clutch to give a free engine. The inlet valves are either fitted to work mechanically or automatically, according to the desire of the purchaser.
