A gasoline bicycle of French manufacture was recentlyexhibited in the United States, attracting considerable 146 WONDERS OF MODERN MECHANISM. attention. Its mechanism is best shown by the accom-panying sketch. There are five cylinders arranged spoke-fashion in the rear wheel, which is the driver, A smallgasoline tank is mounted forward of the steering handles,and is carried down through the frame, as in the Hitch-cock machine, being ignited in the cylinders by an electric Fig. A. FRENCH MOTOR BICYCLE. spark at the riders feet. Just how the gasoline gets tothe cylinders, which are rotating with the wheel, or howthey act on the wheel, is not clear. A pair of runners atthe lower forward side of the rear wheel may be loweredto serve as a brake. The foot-cranks can be used whendesired, but, as the machine weighs one hundred and fortypounds, this would not be very often unless the rider wasfond of hard work. A speed of thirty-two miles an houron a macadamized road is claimed for the machine. Untilthe weight is reduced it can hardly compete with theHitchcock. An interesting motor bicycle has recently been patentedin Germany and has been introduced there and in Wolfmuller and Geisenhof are the inventors. Itsmechanism will be easily understood from the two dia-grams appended, taken from La Nature. It will be ob-served that the rear wheel is soli
