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.
Critical Mass is a form of direct action in which people travel as a group on bicycles at a set location and time. The idea is for people to group together to make it safe for each other to ride bicycles through their streets, based on the old adage: there's safety in numbers.
Bicycle-friendly policies and practices help some people feel more comfortable about traveling by bicycle with other traffic. The level of bicycle-friendliness of an environment can be influenced by many factors including town planning and cycling infrastructure decisions. A stigma towards people who ride bicycles and fear of cycling is a social construct that needs to be fully understood when promoting a bicycle friendly culture.
Utility cycling encompasses any cycling done simply as a means of transport rather than as a sport or leisure activity. It is the original and most common type of cycling in the world. Cycling mobility is one of the various types of private transport and a major part of individual mobility.
Bike lanes (US) or cycle lanes (UK) are types of bikeways (cycleways) with lanes on the roadway for cyclists only. In the United Kingdom, an on-road cycle-lane can be firmly restricted to cycles or advisory. In the United States, a designated bicycle lane or class II bikeway (Caltrans) is always marked by a solid white stripe on the pavement and is for 'preferential use' by bicyclists. There is also a class III bicycle route, which has roadside signs suggesting a route for cyclists, and urging sharing the road. A class IV separated bike way (Caltrans) is a bike lane that is physically separate from motor traffic and restricted to bicyclists only.
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.
Bicycle transportation planning and engineering are the disciplines related to transportation engineering and transportation planning concerning bicycles as a mode of transport and the concomitant study, design and implementation of cycling infrastructure. It includes the study and design of dedicated transport facilities for cyclists as well as mixed-mode environments and how both of these examples can be made to work safely. In jurisdictions such as the United States it is often practiced in conjunction with planning for pedestrians as a part of active transportation planning.
Cycling advocacy consists of activities that call for, promote or enable increased adoption and support for cycling and improved safety and convenience for cyclists, usually within urbanized areas or semi-urban regions. Issues of concern typically include policy, administrative and legal changes ; advocating and establishing better cycling infrastructure ; public education regarding the health, transportational and environmental benefits of cycling for both individuals and communities, cycling and motoring skills; and increasing public and political support for bicycling.
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.
A bicycle boulevard, sometimes referred to as a neighborhood greenway, neighborway, neighborhood bikeway or neighborhood byway is a type of bikeway composed of a low-speed street which has been "optimized" for bicycle traffic. Bicycle boulevards discourage cut-through motor-vehicle traffic but may allow local motor-vehicle traffic at low speeds. They are designed to give priority to bicyclists as through-going traffic. They are intended as a low-cost, politically popular way to create a connected network of streets with good bicyclist comfort and/or safety.
Midnight Ridazz is a late-night group bicycle ride that celebrates bicycle culture in Los Angeles.
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.
Detroit is a popular city for cycling. It is flat with an extensive road network with a number of recreational and competitive opportunities and is, according to cycling advocate David Byrne, one of the top eight biking cities in the world. The city has invested in greenways and bike lanes and other bicycle-friendly infrastructure. Bike rental is available from the riverfront and tours of the city's architecture can be booked.
Bicycle use in Portland, Oregon has been growing rapidly, having nearly tripled since 2001; for example, bicycle traffic on four of the Willamette River bridges has increased from 2,855 before 1992 to over 16,000 in 2008, partly due to improved facilities. The Portland Bureau of Transportation says 6% of commuters bike to work in Portland, the highest proportion of any major U.S. city and about 10 times the national average.
Cycling in San Francisco has grown in popularity in recent years, aided by improving cycling infrastructure and community support. San Francisco's compact urban form and mild climate enable cyclists to reach work, shopping, and recreational destinations quickly and comfortably. Though San Francisco's famed steep hills can make cycling difficult, many parts of the city are relatively flat, including some of the most densely populated. However, heavy automobile traffic, the lack of bike lanes on many streets, and difficulty in crossing major streets deter most residents from cycling frequently in San Francisco.
Cycling in Denmark is both a common and popular recreational and utilitarian activity. Bicycling infrastructure is a dominant feature of both city and countryside infrastructure with segregated dedicated bicycle paths and lanes in many places and the network of 11 Danish National Cycle Routes extends more than 12,000 kilometres (7,500 mi) nationwide. Often bicycling and bicycle culture in Denmark is compared to the Netherlands as a bicycle-nation.
Cycling in Atlanta has grown in popularity in recent years, from 0.33% of commutes in 2000 to 1.1% in 2009, aided by improving cycling infrastructure and community support. Although Atlanta has historically been a city defined by the automobile, its increasingly compact urban form and mild climate are encouraging residents to cycle to work, shopping, and recreational destinations. Though Atlanta's famed hilly topography can make cycling challenging, though fun, many parts of the city are relatively flat, including some of the more densely populated areas. However, heavy automobile traffic, the lack of bike lanes on many streets, and difficulty in crossing major streets deter most residents from cycling frequently in Atlanta.
The history of cycling infrastructure starts from shortly after the bike boom of the 1880s when the first short stretches of dedicated bicycle infrastructure were built, through to the rise of the automobile from the mid-20th century onwards and the concomitant decline of cycling as a means of transport, to cycling's comeback from the 1970s onwards.
Cycling infrastructure in the Canadian city of Halifax, Nova Scotia includes most regular streets and roads, bike lanes, protected cycle tracks, local street bikeways, and multi-use pathways.
