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.
Cycling, also known as bicycling or biking, is the activity of riding a bicycle or other type of cycle. It encompasses the use of human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles. Cycling is practised around the world for purposes including transport, recreation, exercise, and competitive sport.
A bicycle helmet is a type of helmet designed to attenuate impacts to the head of a cyclist in collisions while minimizing side effects such as interference with peripheral vision.
Bicycle law in California is the parts of the California Vehicle Code that set out the law for persons cycling in California, and a subset of bicycle law in the United States. In general, pretty much all the same rights and responsibilities that apply to car drivers apply to bicycle riders as well.
Cycling in Melbourne, the capital city of Victoria, Australia, is enhanced by the city's relatively flat topography and generally mild climate. The city has an active cycling culture for commuting, recreation, fitness and sport, and the metropolitan area has an extensive network of off-road bicycle paths, as well as designated bicycle lanes on many streets.
Vehicular cycling is the practice of riding bicycles on roads in a manner that is in accordance with the principles for driving in traffic, and in a way that places responsibility for safety on the individual.
Dooring is the act of opening a motor vehicle door into the path of another road user. Dooring can happen when a driver has parked or stopped to exit their vehicle, or when passengers egress from cars, taxis and rideshares into the path of a cyclist in an adjacent travel lane. The width of the door zone in which this can happen varies, depending upon the model of car one is passing. The zone can be almost zero for a vehicle with sliding or gull-wing doors or much larger for a truck. In many cities across the globe, doorings are among the most common and injurious bike-vehicle incidents. Any passing vehicle may also strike and damage a negligently opened or left open door, or injure or kill the exiting motorist or passenger.
This is a glossary of terms and jargon used in cycling, mountain biking, and cycle sport.
A motorized bicycle is a bicycle with an attached motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit a power-assisted one. Typically they are incapable of speeds above 52 km/h (32 mph), however in recent years larger motors have been built, allowing bikes to reach speeds of upwards of 72 km/h.
Bicycle safety is the use of road traffic safety practices to reduce risk associated with cycling. Risk can be defined as the number of incidents occurring for a given amount of cycling. Some of this subject matter is hotly debated: for example, which types of cycling environment or cycling infrastructure is safest for cyclists. The merits of obeying the traffic laws and using bicycle lighting at night are less controversial. Wearing a bicycle helmet may reduce the chance of head injury in the event of a crash.
Many countries have enacted electric vehicle laws to regulate the use of electric bicycles, also termed e-bikes. Some jurisdictions have regulations governing safety requirements and standards of manufacture. The members of the European Union and other regions have wider-ranging legislation covering use and safety.
Cycling is the second-most common mode of transport in the Netherlands, with 36% of Dutch people listing the bicycle as their most frequent way of getting around on a typical day, as opposed to the car (45%) and public transport (11%). Cycling has a modal share of 27% of all trips nationwide. In cities this is even higher, such as Amsterdam which has 38%, and Zwolle 46%. This high frequency of bicycle travel is enabled by excellent cycling infrastructure such as cycle paths, cycle tracks, protected intersections, ample bicycle parking and by making cycling routes shorter and more direct than car routes.
Cycling in New Zealand, while relatively popular as a sport, is a very marginal commuting mode, with the share hovering around 1–3% in most major cities. This is due to a number of factors, principally safety fears.
Bike rage refers to form of road rage in which acts of verbal or gestural anger or physical aggression between cyclists and other users of bike paths or roadways, including pedestrians, other cyclists, motorcyclists, or drivers. Bike rage can consist of shouting at other road users, making obscene gestures or threats, hitting or punching, or in rare cases, even more violent acts. The term can refer either to acts committed by cyclists or by other road users against cyclists. Bike rage is related to other explosive outbursts of anger such as road rage.
Cycling in Illinois encompasses recreation, bikeways, laws and rules, and advocacy. The director of the Illinois Department of Natural Resources, Joel Brunsvold, explained Illinois cycling opportunities: “Bicycle riding is one of the most popular outdoor recreational activities in Illinois, enjoyed by young and old alike...Illinois has a variety of trails for the public to enjoy. The terrain includes flat prairie land to rolling hills, towering bluffs to the breathtaking river and lakefront views.” Many communities across the state are updating bicycle infrastructure in order to accommodate the increased number of cyclists on the roads.
Cycling in Canada is experienced in various ways across a geographically huge, economically and socially diverse country. Among the reasons for cycling in Canada are for practical reasons such as commuting to work or school, for sports such as road racing, BMX, Mountain bike racing, freestyle BMX, as well as for pure recreation. The amount and quality of bicycle infrastructure varies widely across the country as do the laws pertaining to cyclists such as bicycle helmet laws which can differ by province.
Cycling infrastructure is all infrastructure cyclists are allowed to use. Bikeways include bike paths, bike lanes, cycle tracks, rail trails and, where permitted, sidewalks. Roads used by motorists are also cycling infrastructure, except where cyclists are barred such as many freeways/motorways. It includes amenities such as bike racks for parking, shelters, service centers and specialized traffic signs and signals. The more cycling infrastructure, the more people get about by bicycle.
A protected intersection or protected junction, also known as a Dutch-style junction, is a type of at-grade road junction in which cyclists and pedestrians are separated from cars. The primary aim of junction protection is to help pedestrians and cyclists be and feel safer at road junctions.
There is debate over the safety implications of cycling infrastructure. Recent studies generally affirm that segregated cycle tracks have a better safety record between intersections than cycling on major roads in traffic. Furthermore, cycling infrastructure tends to lead to more people cycling. A higher modal share of people cycling is correlated with lower incidences of cyclist fatalities, leading to a "safety in numbers" effect though some contributors caution against this hypothesis. On the contrary, Older studies tended to come to negative conclusions about mid-block cycle track safety.
Cold-weather biking, cold-weather cycling, or winter biking is the use of a bicycle during months when roads and paths are covered with ice, slush and snow. Cold weather cyclists face a number of challenges in near or below freezing temperatures. Urban commuters on city streets may have to deal with "[s]now, slush, salt, and sand", which can cause rust and damage to metal bike components. Slush and ice can jam derailleurs. Some cyclists may bike differently in winter, by "slow[ing] down on turns and brak[ing] gradually" in icy conditions. Gaining traction on snow and ice-covered roads can be difficult. Winter cyclists may use bikes with front and rear fenders, metal studded winter tires and flashing LED lights. Winter cyclists may wear layers of warm clothes and "ea[r], face, and han[d]" coverings may be used. Specialized winter bikes called fatbikes, which have wide, oversized tires that are typically inflated with low pressure, are used in snow trail riding and winter bike competitions.
