RIDER PROPULSION OF WHEELED VEHICLES OR SLEDGES

**Definition:** This place covers:

Rider propulsion of wheeled vehicles, e.g. cycles having two or more wheels, using essentially the mechanical energy of the rider, e.g. by hand or feet, to propel the vehicle.

Rider propulsion of wheeled vehicles as above with additional source of power, e.g. combustion engines or electric motors, said additional source of power might be used in addition according the need of the rider.

Propulsion devices for sledges or the like, e.g. snow vehicles with or without engine, cycles having an endless tracks rather than wheels, motor powered sledges.

Vehicles, e.g. motorcycles, characterised by position of motor or engine with respect to vehicle frame, wheels or other components. Motorcycle aspects in relation to support or mounting of engine or motor, the exhaust system, cooling system, mufflers, air intake or the arrangements of accessories.

Transmission aspects characterised by the use of an endless flexible members, e.g. chains, inter-engaging toothed wheels, or frictionally engaging wheels or friction rollers engaging the periphery of a ground wheel.

Transmission characterised by rotary shafts, e.g. cardan shafts, or non-mechanical gearing, e.g. fluid gearing.

Transmission for hybrid motorcycles, e.g. having an electric motor and a internal combustion engine.

Pedals or cranks

Actuators for speed change mechanisms specially adapted for cycles.

**Glossary:** - Transmissions: The term transmission means all parts between the prime mover or the part to which a rider immediately applies propulsion effort, e.g. pedal cranks, and a driven ground wheel.
