Touring motor bicycle

A touring motor bicycle, fitted with luggage carrier and stand, the latter for supporting the bicycle while at rest. The average speed of a motor bicycle being much greater than that of a pedal bicycle the stresses on the frame due to moving over rough roads are greater. The necessitates greater strength and weight in all parts--frame, wheels, and tires. To take this increased weight up steep gradients requires increased engine power. The weight of a touring bicycle may be from 150 to 200 lb. The drive is usualy by a V belt of leather, or of canvas and rubber, the angle of the V being 28 degrees. The engine speed at maximum power is from 1500 to 2000 revolutions a minute, and the belt gears down in a ratio varying between 1/3 and 1/6 according to the cylinder capacity of the engine.
