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]
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.
Three-speed bicycle. The three-speed bicycle is a bicycle that uses internal hub gears at the rear wheel hub to provide three gear ratios. Three-speed hubs have been in use since the early 1900s. Though they are heavier than comparable derailleur systems, internal-gear hub systems generally last longer and require less maintenance.
The mountain bike's sturdy frame and load-carrying ability gave it additional versatility as a utility bike, usurping the role previously filled by the roadster. By 1990, the roadster was almost dead; while annual UK bicycle sales reached an all-time record of 2.8 million, almost all of them were mountain and road/sport models.
