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]
Freehub vs freewheel hub. The freehub concept answers several drawbacks encountered with the freewheel design: Freewheels are threaded onto an axle hub, using conventional right-hand threads. As the bicycle rider pedals, the freewheel is continuously kept tight, as chain torque is in the right-hand direction. This becomes a problem when the ...
Portage strap: a strap (usually made of leather) attached to the inside of the bike frame, designed to make carrying the bike over one's shoulder easier; Pulley wheel: see Jockey wheel; Power meter: a device on a bicycle that measures the power output of the rider; Quick release: a skewer with a lever on one end that loosens when the lever is ...
The Flying Pigeon PA-02, a single-speed utility bicycle, is the most produced bicycle model in history. A single-speed bicycle is a type of bicycle with a single gear ratio . These bicycles are without derailleur gears , hub gearing or other methods for varying the gear ratio of the bicycle.
The simplest freewheel device consists of two saw-toothed, spring-loaded discs pressing against each other axially with the toothed sides together, like a ratchet but with the usual stationary part also rotating. Rotating in one direction, the saw teeth of the drive disc lock with the teeth of the driven disc, making it rotate at the same speed.
This page lists notable bicycle brands and manufacturing companies past and present. For bicycle parts, see List of bicycle part manufacturing companies.. Many bicycle brands do not manufacture their own product, but rather import and re-brand bikes manufactured by others (e.g., Nishiki), sometimes designing the bike, specifying the equipment, and providing quality control.
The Shimano Front Freewheel (FFS) was a proprietary bicycle drivetrain design of the 1970s that placed a freewheel between the pedal cranks and the front chainrings – enabling the rider to shift gears while coasting. [2] FFS rear freewheel is different than a standard freewheel because it's "stiff" with more friction than a normal rear freewheel.
Single-speed mountain bike. A single-speed bicycle is a type of bicycle with a single gear ratio and a freewheel mechanism. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle. Adult single-speed bicycles typically have a gear ratio of between 55 and 75 gear inches, depending on ...
