MOTOR AUXILIARY FOR BICYCLES.

! A power attachment ror bicycles has recently been invented which '. calls for no structiral alterations to be made in the ordinary bicycle, and which can be attached or detached in a few minutes. Tne device comprises a small auxiliary wheal, 20in., j in diameter, fitted with a light motor, which is connected to the rear wheel of the bicycle. An ingenious pivoting arrangement allows the wheel a peculiar lateral and vertical movement, so ttjat the steering of the machine is in no way affected, and permits the wheel to glide over obstacles or rough ground without, transmitting any shock or vibration to the rider. The motor is a small, air-cooled, horizontal, two-stroke engine with a specially designed hub to which the power is transmitted through to a six to one reducing gear. The magneto ignition and vapouriser are mounted un the same plane, and in line with the engine, so that the whole is rendered very compact. The engine is valveless, the inlet and exhaust being governed I by ports, alternately covered and] uncovered by the piston. It develops 31 horse-power. To attach the motor wheel to the ordinary cycle, it is oply necessary to remove the nut >of the machine, and to attach the frame of the auxiliary wheel to the spindle and bolt it up—an operation occupyiiig a few moments. A 6ingle lever regulator controlling the motor is clipped to th2 handle-bar, the connection with the motor mechanism being a flexible wire. This, single, lever controls the action of the engine to a nicety. The wheel complete wejghs only 251bs>, and the motor is capable of driving the bicycle at an average speed of sixteen miles pe..* hour on an ordinary road, with a maximum speed of eighteen miles on the level. The fuel tank in the mud-guard is of sufficient capacity to carry the motor 100 miles.
