Utility cycling encompasses any cycling not done primarily for fitness, recreation such as cycle touring, or sport such as cycle racing, but simply as a means of transport. It is the most common type of cycling in the world. In the Chinese city of Beijing alone, there are an estimated four million bicycles in use (it has been estimated that in the early-1980s there were approximately 500 million cyclists in China). As of 2000, there were an estimated 80 million bicycles in Japan, accounting for 17% of commuter trips, and in the Netherlands, 27% of all trips are made by bicycle. Utility or "transportational" cycling generally involves travelling short and medium distances (several kilometres, not uncommonly 3-15 kilometers one way, or somewhat longer). It includes commuting, going to school, high school or college, running errands, and delivering goods or services. In cities, the bicycle courier is often a familiar feature, and freight bicycles are capable of competing with trucks and vans particularly where many small deliveries are required, especially in congested areas. Velotaxis can also provide a public transport service like buses and taxicabs.
Utility cycling is believed to have several social and economic benefits. Policies that encourage utility cycling have been proposed and implemented for reasons including: improved public health , individual health and employers' profits a reduction in traffic congestion and air pollution, improvements in road-traffic safety, improved quality of life, improved mobility and social inclusiveness, and benefits to child development.
Utility bicycles have many standard features to enhance their usefulness and comfort. Chain-guards and mudguards, or fenders, protect clothes and moving parts from oil and spray. Kick stands help with parking. Front-mounted wicker or steel baskets for carrying goods are often used. Rear luggage carriers can be used to carry items such as school satchels. Panniers or special luggage carriers (including waterproof packing bags) enable the transport of goods and are useful for shopping. Parents sometimes add rear-mounted child seats and/or an auxiliary saddle fitted to the crossbar to transport children. Trailers of various types and load capacities may be towed to greatly increase cargo capacity. In many jurisdictions bicycles must be fitted with a bell; reflectors; and, after dark, front and rear lights.
The use by cyclists of vests or armbands fluorescent in daylight or reflective at night can increase a cyclist's conspicuity, although these are not an alternative to a legally compliant lighting system. A report on the promotion of walking and cycling (Hydén, et al., 1999) discussed safety clothing and equipment and stated that "there is no doubt that both pedestrian reflectors and bicycle helmets are reducing the injury risk of their users quite considerably." Protective rain gear is often an essential part of the utility cyclist's wardrobe, especially in countries with high rainfall levels.
Many different factors combine to influence levels of utility cycling. In developing economies, a large amount of utility cycling may be seen simply because the bicycle is the most affordable form of vehicular transport available to many people. In richer countries, where people can have the choice of a mixture of transport types, a complex interplay of other factors influences the level of bicycle use. Factors affecting cycling levels may include: town planning (including quality of infrastructure: cyclist "friendly" vs. cyclist "hostile"), trip-end facilities (particularly secure parking), retail policy, marketing the public image of cycling, integration with other transport modes, cycle training, terrain (hilly vs. flat), and climate. In developed countries cycling has to compete with, and work with, alternative transport modes such as private cars, public transport and walking. Thus cycling levels are not influenced just by the attractiveness of cycling alone, but also by what makes the competing modes more or less attractive.
In developed countries with high utility cycling levels, utility cyclists tend to undertake relatively short journeys. According to Irish 1996 Census data, over 55% of cycling workers travelled 3 miles (4.8 km) or less, 27% 5 miles (8 km) or less and only 17% travelled more than 5 miles in their daily commute. It can be argued that factors that directly influence trip length or journey time are among the most important in making cycling a competitive transport mode. Car ownership rates can also be influential. In New York City, more than half of all households do not own a car (the figure is even higher in Manhattan, over 75%), and walk/bicycle modes of travel account for 21% of all modes for trips in the city.
Decisions taken by various levels of government, as well as local groups, residents' organisations and public- and private-sector employers, can all have an impact on the so-called "modal choice" or "modal split" in daily transport. In some cases various factors may be manipulated in a manner that deliberately seeks to encourage or discourage various transport modes, including cycling.
The League of American Bicyclists has designated a set of five criteria for evaluating the friendliness of a town or city to bicycles. These criteria are classified under the headings of: Engineering, Encouragement, Evaluation and Planning, Education, Enforcement.
Trip length and journey times are key factors affecting cycle use. Town planning may have a key impact in deciding whether key destinations, schools, shops, colleges, health clinics, public transport interchanges remain within a reasonable cycling distance of the areas where people live. The urban form can influence these issues, compact and circular settlement patterns tending to promote cycling. Alternatively, the low-density, non-circular (i.e., linear) settlement patterns characteristic of urban sprawl tends to discourage cycling. In 1990, the Dutch adopted the "ABC" guidelines, specifically limiting developments that are major attractants to locations that are readily accessible by non-car users.
Settlements that provide a dense road network consisting of interconnected streets will tend to be viable utility cycling environments. In contrast, other communities may use a cul-de-sac based, housing estate/housing subdivision model where minor roads are disconnected and only feed into a street hierarchy of progressively more "arterial" type roads. Such communities may discourage cycling by imposing unnecessary detours and forcing all cyclists onto arterial roads, which may be perceived as busy and dangerous, for all trips regardless of destination or purpose. There is evidence that people who live in such estates are heavier than people who live in places where walking and cycling are more convenient. It is also reported that the extra motor-traffic such communities generate tends to increase overall per-capita traffic casualty rates. Designs that propose to resolve the contradiction between the cul-de-sac and the traditional interconnected network, such as the Fused Grid, have been proposed and built with varying levels of success. Particular issues have arisen with personal security and public order problems in some housing schemes using "back alley" type links.
The cycling infrastructure comprises all the public ways that are available to cyclists travelling from one destination to another. This includes the same network of public roads that is available for other road vehicle users, minus those roads from which cyclists have been banned (most freeways), plus additional routes that are not available to other types of vehicle, such as cycle tracks and (in some jurisdictions) sidewalks.
The manner in which the public roads network is designed, built and managed can have a significant effect on the utility and safety of cycling as a form of transport. The key issue is whether the cycling network provides the users with direct, convenient routes minimising unnecessary delay and effort in reaching key destinations. Settlements that provide a dense roads network consisting of interconnected streets will tend to be viable utility cycling environments.
