A track bicycle or track bike is a form of fixed-gear bicycle optimized for racing at a velodrome or at an outdoor track. Some road racing and club cyclists use a fixed-gear bicycle for training during the winter months, generally using a relatively low gear ratio, believed to help develop a good pedalling style. [5]

A belt-driven bicycle is a chainless bicycle that uses a flexible belt, typically a synchronous toothed design, in order to transmit power from the pedals to the ...
A chain drive and rear derailleur gear change, the most popular system in use today A shaft-drive with crankset and rear gear hub. Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels.
Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns. On some bicycles there is only one gear and, therefore, the gear ratio is fixed , but most modern bicycles have multiple gears and thus multiple gear ratios.
Shaft-drive: alternate to chain-drive; Shifter: gear shifting control; Shock absorber: for bicycles with suspensions, a device that limits the rate at which suspension rebounds after absorbing an impact; Side view mirror: aids in looking at the sides prior to moving slowly or turning to the left or to the right
A pedal cycle, commonly known as a bicycle is driven by legs and feet on pedals. A hand-cranked bicycle or handcycle is driven by arms and hands. A rowing cycle is driven by a rowing action using both arms and legs. A treadle bicycle is driven by a reciprocating, not rotary, motion of the feet. A bucking bike (with one or more eccentric wheels ...
This is called "chain drive" and "belt drive" respectively. Besides connecting the engine to a sprocket, the engine can also be connected directly to the crank. This is called "crank drive" [43] or "mid-drive" [44] and also allows incorporating the gears of the bicycle in the motorized system. Most of these bikes and kits are under 50 cc and do ...
Before epicyclic gears were used in bicycle hubs, they were used on tricycles. Patents for epicyclic hubs date from the mid-1880s. [5] [6] The first patent for a compact epicyclic hub gear was granted in 1895 to the American machinist Seward Thomas Johnson of Noblesville, Indiana, U.S.A. [7] This was a 2-speed but was not commercially successful.
