I. - MOTORCYCLES.

At the show, there were 28 motorcycles with reinforced frames, built to be operated mechanically, and 4 ordinary bicycles to which a motor had been fitted.

December 1901 Paris Salon

§ 1. - Werner motorcycle.

As a type in the first category, one can take the Werner 1902 motorcycle (Fig. 1), the fifth model created by this house, the first of which dates back to 1897. The motor, a three-quarter horse, powered by a carburettor Spray and equipped with electric ignition with accumulators and coil, is arranged vertically at the bottom of the frame, instead of the pedal, which has been moved back. The movement is transmitted by a belt to a pulley mounted on the rear wheel. The motorcycle runs at a speed of 10 to 50 kilometers per hour; she weighs 35 kg.

§ 2. - Peugeot motorcycle.

It is also the weight of the Peugeot motorcycle, whose motor, one and a half horsepower, narrow enough to be housed between the pedals, is tilted below the part of the frame that connects the crankset to the fork. Its speed is 25 to 40 kilometers per hour.

§ 2. - Motobicyclette Peugeot. C’est aussi le poids de la motobicyclette Peugeot, dont le moteur, d’un cheval et demi, assez étroit pour être logé entre les pédales, est incliné au-dessous de la partie du cadre qui relie le pédalier à la fourche. Sa vitesse en palier est de 25 à 40 kilomètres par heure.

§ 3. - Clement's motorcycle.

The Clément autoclette has its engine lying on the inclined side of the frame near the fork; his power, from a horse to 1,900 turns, can print him a speed of 40 kilometers per hour.

§ 4. - Bicycle Chapel.

Its engine is arranged vertically, like that of the Werner motorcycle; it is equipped with a gearshift, and it has, in race, up to 60 kilometers per hour.

§ 5. - Demester.

The Demester oil bicycle can, it is said, make 70 km/h; it has a 3-horsepower, two-cylinder engine, placed vertically on the underside of the frame, between the crankset and the rear wheel. The transmission of the movement to the latter is by chains and toothed wheels. It weighs 48 kg, in which the engine enters for 18 kg.

§ 6. - Ordinary motorcycles.

To mechanically operate an ordinary bicycle, you can use a Brutus engine , which weighs 8 kg and gives a horse and a quarter or a horse and a half. It is fixed vertically in the frame, near the fork. Its movement is transmitted to the wheel by a belt with tensioner.

We can also use a Knap motor, 6 kg and a half, normally 2,400 revolutions per minute and directly attacking, by a pinion and a gear wheel, the hub of the rear wheel, near which it is mounted vertically. A bag-tank is placed on the upper side of the frame. The bicycle, which weighs 14.8 kg with brake and freewheel, does not exceed, in running order, the weight of 28 kg. Five minutes is enough to get rid of the engine and its accessories.

The motorbike Dufaux is formed of steel tubes, which follow the inner shape of the frame and which carry the motor (of a horse and a quarter) and its accessories; carburetor, tank, battery, coil. A joystick, controlling the starting and disengaging, and a switch constitute all the control members; the transmission is done by a belt and a grooved pulley.

§ 6. - Bicyclettes ordinaires à moteur. Pour actionner mécaniquement une bicyclette ordinaire, on peut avoir recours à un moteur Brutus, qui pèse 8 kg et donne un cheval et quart ou un cheval et demi. Il se fixe verticalement dans le cadre, près de la fourche. Son mouvement est transmis à la roue par une courroie avec tendeur. On peut aussi employer un moteur Knap, de 6 kg et demi, faisant normalement 2.400 tours à la minute et attaquant directement, par un pignon et une roue dentés, le moyeu de la roue arrière, près duquel il est monté verticalement. Une sacoche-réservoir est placée sur le côté supérieur du cadre. La bicyclette, qui pèse 14,8 kg avec frein et roue libre, ne dépasse pas, en ordre de marche, le poids de 28 kg. Cinq minutes suffisent pour la débarrasser du moteur et de ses accessoires. La motosacoche Dufaux est formée de tubes d’acier, qui épousent la forme intérieure du cadre et qui portent le moteur (d’un cheval et quart) et ses accessoires ; carburateur, réservoir, pile, bobine. Une manette, commandant la mise en marche et le débrayage, et un interrupteur constituent tous les organes de commande ; la transmission se fait par une courroie et une poulie à gorge.

I. - MOTOCYCLETTES.

§ 4. - Bicyclette Chapelle. Son moteur est disposé verticalement, ’comme celui de la motocyclette Werner ; elle est pourvue d’un changement de vitesse, et elle a fait, en course, jusqu’à 60 kilomètres à l’heure.

§ 5. - Bicyclette Demester. La bicyclette à pétrole Demester peut, dit-on, faire du 70 ; elle a un moteur de 3 chevaux à deux cylindres, placé verticalement sur le côté inférieur du cadre, entre le pédalier et la roue d’arrière. La transmission du mouvement à cette dernière se fait par chaînes et roues dentées. Elle pèse 48 kg, dans lesquels le moteur entre pour 18 kg.


René Gillet

Exhibited a single-cylinder motor at the 1902 Salon but being unknown to the organizers he was relegated to a corner of the first floor. In 1903, he returned to the show and began to achieve recognition.
