A bicycle, also called a bike or cycle, is a human-powered or motor-powered, 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 bicycle brake reduces the speed of a bicycle or prevents it from moving. The three main types are: rim brakes, disc brakes, and drum brakes.
Bicycle messengers are people who work for courier companies carrying and delivering items by bicycle. Bicycle messengers are most often found in the central business districts of metropolitan areas. Courier companies use bike messengers because bicycle travel is less subject to unexpected holdups in city traffic jams, and is not deterred by parking limitations, fees or fines in high-density development that can hinder or prevent delivery by motor vehicle, thereby offering a predictable delivery time.
Indoor cycling, often also called spinning, as an organized sport, 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.
Cycle sport is competitive physical activity using bicycles. There are several categories of bicycle racing including road bicycle racing, time trialling, cyclo-cross, mountain bike racing, track cycling, BMX, and cycle speedway. Non-racing cycling sports include artistic cycling, cycle polo, freestyle BMX and mountain bike trials. The Union Cycliste Internationale (UCI) is the world governing body for cycling and international competitive cycling events. The International Human Powered Vehicle Association is the governing body for human-powered vehicles that imposes far fewer restrictions on their design than does the UCI. The UltraMarathon Cycling Association is the governing body for many ultra-distance cycling races.
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 stationary bicycle is a device used as exercise equipment for indoor cycling. It includes a saddle, pedals, and some form of handlebars arranged as on a (stationary) bicycle.
A fixed-gear bicycle is a bicycle that has a drivetrain with no freewheel mechanism. 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.
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.
Gitane is a French manufacturer of bicycles based in Machecoul, France; the name "Gitane" means gypsy woman. The brand was synonymous with French bicycle racing from the 1960s through the mid-1980s, sponsoring riders such as Jacques Anquetil (1963–1965), Lucien Van Impe (1974–1976), Bernard Hinault (1975–1983), Laurent Fignon (1982–1988), and Greg LeMond (1981–1984). It is owned by Grimaldi Industri AB.
This is a glossary of terms and jargon used in cycling, mountain biking, and cycle sport.
A bicycle trainer is a piece of equipment that makes it possible to ride a bicycle while it remains stationary. They are commonly used to warm up before races, or when riding conditions outside are not favorable.
Felt Racing is an American bicycle brand based in Irvine, California. Felt produces road, mountain, track, cyclocross, electric bicycles, and cruiser bikes. All design is completed in the USA and the majority of production comes from Asia. The company also has a strong reputation in the time trial/triathlon bike area and for several years provided bicycles to UCI teams in the Tour de France. Felt still supports several professional level race teams including Hincapie Racing and Team Twenty 16.
Bicycle rollers are a type of bicycle trainer that make it possible to ride a bicycle indoors without moving forward. However, unlike other types of bicycle trainers, rollers do not attach to the bicycle frame, and the rider must maintain balance on the rollers while training. Bicycle rollers normally consist of three cylinders, drums, or "rollers", on top of which the bicycle rides. A belt connects the middle roller to the front roller, causing the front wheel of the bicycle to spin when the bicycle is pedaled. The spacing of bicycle rollers can usually be adjusted to match the bicycle's wheelbase. Generally, the front roller is adjusted to be slightly ahead of the hub of the front wheel.
An alley cat race is an unsanctioned bicycle race. Alley cats almost always take place in cities, and are often organized by bicycle messengers. The informality of the organization is matched by the emphasis on taking part, rather than simple competition. For instance, many alleycats present prizes for the last competitor to finish . The first race to be called an 'alley cat' was held in Toronto on 30 October 1989 and continued, in its original form, around Halloween and Valentine's Day for the following five years. In 1993, when Toronto messengers shared Alleycat stories at the first international messenger race, the name and the concept spread far and wide. Regularly organized Alleycats can be found in cities across North America, Europe and Asia. Many smaller cities with no cycle messenger population are also home to alleycats run by the burgeoning urban cyclist subculture.
The British National Derny Championships are annual bicycle races held in the UK.
The following outline is provided as an overview of and topical guide to bicycles:
The Cycle Messenger World Championships, or CMWCs, are an annual urban cycling competition whereby cycle messengers and cycling enthusiasts showcase their skills in an array of events, many of which simulate everyday tasks for a cycle messenger. Each year, the CMWCs are held in a different city around the world, with each host city designing its own unique course. The highlight of the CMWCs is the main race in which cyclists are given manifests and must pickup and deliver items to various locations around the host city as quickly and efficiently as possible. The total number of pickups and deliveries, or "drop offs" is unknown to the messengers before the race, but has been known to reach up to 100 stops and usually takes between 3–4 hours to complete. The cyclist who completes all of the assigned deliveries in the least amount of time wins the race. In addition to the main race there are also several side events which have become increasingly popular over the past few years. These events change yearly depending on the discretion of the host city but usually include backward circles, bike polo, bunnyhop, cargo race, longest skid, sprints, and trackstand.
Condor Cycles is a bicycle manufacturer based on Gray’s Inn Road in London. Condor Cycles was started in 1948 by Monty Young, providing bespoke bicycles which have been ridden by riders such as Tom Simpson, Bradley Wiggins, and Tao Geoghegan Hart. Condor bicycles have been ridden to World Championship gold medals and ridden in the Tour de France.
