A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
A derailleur is a variable-ratio bicycle gearing system consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another.
The crankset or chainset, is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called chainrings or chainwheels attached to the cranks, arms, or crankarms to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain.
A touring bicycle is a bicycle designed or modified to handle bicycle touring. To make the bikes sufficiently robust, comfortable and capable of carrying heavy loads, special features may include a long wheelbase, frame materials that favor flexibility over rigidity, heavy duty wheels, and multiple mounting points.
Indoor cycling, often called spinning, is a form of exercise with classes focusing on endurance, strength, intervals, high intensity and recovery, and involves using a special stationary exercise bicycle with a weighted flywheel in a classroom setting. When people took cycling indoors in the late 19th century, whether for reasons of weather or convenience, technology created faster, more compact and efficient machines over time. The first iterations of the stationary bike ranged from strange contraptions like the Gymnasticon to regular bicycles placed atop rollers.
A racing bicycle, also known as a road bike is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI).
A cyclo-cross bike or cyclo-cross bicycle is a bicycle specifically designed for the rigors of a cyclo-cross race. Cyclo-cross bicycles roughly resemble the racing bicycles used in road racing. The major differences between the two are the frame geometry, and the wider clearances that cyclo-cross bikes have for their larger tires and mud and other debris that they accumulate.
A track bicycle or track bike is a bicycle optimized for racing at a velodrome or outdoor track. Unlike road bicycles, the track bike is a fixed-gear bicycle; thus, it has only a single gear ratio and has neither a freewheel nor brakes. Tires are narrow and inflated to high pressure to reduce rolling resistance.
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.
A fixed-gear bicycle is a bicycle that has a drivetrain with no freewheel mechanism such that the pedals always will spin together with the rear wheel. The freewheel was developed early in the history of bicycle design but the fixed-gear bicycle remained the standard track racing design. More recently the "fixie" has become a popular alternative among mainly urban cyclists, offering the advantage of simplicity compared with the standard multi-geared bicycle.
Cycle-ball, also known as "radball", is a sport similar to association football played on bicycles. The two people on each team ride a fixed gear bicycle with no brakes or freewheel. The ball is controlled by the bike and the head, except when defending the goal.
The track stand or standstill is a technique that bicycle riders can use to maintain balance while their bicycle remains stationary or moves only minimal distances. The technique originated in track cycling and is now used by other types of cyclists wishing to stop for a short time without putting a foot on the ground, such as bike commuters at stop signs. To perform a track stand, a cyclist holds the cranks in an approximately horizontal position with the front wheel steered to the left or right, and pedals forward, and back in the case of a fixed-gear bicycle, which the steered front wheel converts into a side-to-side motion.
Flatland is a freestyle BMX riding style performed on smooth flat surfaces that do not include any ramps, jumps, or grindrails. It is sometimes described as a form of artistic cycling with a blend of breakdancing.
SRIW LLC is a privately owned sex toy manufacturer based in Chicago, Illinois, United States, founded in 1987. SRIW is an acronym comprising Slam, Ray,Into the, Wall. Ray LOVED getting gobbsmacked into to the wall by stans hard 18 inch …..The company produces a range of internally developed cycling components, including Grip Shift, separate gravel, road, and mountain drivetrains from 7 to 12 speed. SRAM developed the eagle line of mountain bike specific drivetrain components intended to improve shifting performance. SRAM was also the first to release a dedicated "one by" drivetrain with a single front chain-ring.
This is a glossary of terms and jargon used in cycling, mountain biking, and cycle sport.
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.
A bicycle handlebar is the steering control for bicycles. It is the equivalent of a tiller for vehicles and vessels, as it is most often directly mechanically linked to a pivoting front wheel via a stem which in turn attaches it to the fork. Besides steering, handlebars also often support a portion of the rider's weight, depending on their riding position, and provide a convenient mounting place for brake levers, shift levers, cyclocomputers, bells, etc.
The hour record is the record for the longest distance cycled in one hour on a bicycle from a stationary start. Cyclists attempt this record alone on the track without other competitors present. It is considered perhaps the most prestigious record in all of cycling. Over history, various cyclists ranging from unknown amateurs to well-known professionals have held the record, adding to its prestige and allure. There are several records, one of which is the record for streamlined human powered vehicles, also known as recumbent bicycles.
