Ixion engine on a Komet motorised bicycle, ca. 1902. This system is used, for example, to drive the spools in some tape recorders.In a typical configuration, one of the cylinders is the axle of an electric motor, say 1 mm in diameter, while the other is a disk with a hard rubber rim, say 50 mm in diameter, yielding a 1:50 mechanical advantage.
The VéloSoleX was a mass-produced motorized bicycle that used a tire roller (friction drive) to the front wheel. After French production ceased, the VELOSOLEX continued to be produced in China and Hungary. An in-wheel gasoline engine was used on the Honda P50 moped, which ceased production in 1968.
1982 – The "Bumble Bike" friction drive (now Golden Eagle belt drive) is chosen as "Official Transportation" at the Knoxville Worlds Fair. 1985 – The Tour de Sol leads to the development of modern electric bicycles in Switzerland. 1986 – A group of Swiss students develops the Twike sociable tricycle.
Basket: it is an optional attachment on a bike and is used for carrying things; Bearing: a device that facilitates rotation by reducing friction; Bell: an audible device for warning pedestrians and other cyclists; Belt-drive: alternative to chain-drive; Bicycle brake cable: see Cable; Bottle cage: a holder for a water bottle
Rubbee Drive is a 250W friction drive module which fits most standard bicycles. [1] It enables a bicycle to reach up to 25 km/h speed and travel 40 km, making it a viable option for daily commuting. [2] The units are assembled by JSC ELINTA in Lithuania.
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of ...
