Utility bicycle
A utility bicycle, city bicycle, urban bicycle, European city bike, Dutch bike, classic bike or simply city-bike is a bicycle designed for frequent short rides through urban areas. It is a form of utility bicycle commonly seen around the world, built to facilitate everyday riding in normal clothes in a variety of weather conditions. It is therefore a bicycle designed for practical transportation, as opposed to those primarily for recreation and competition, such as touring bicycles, road bicycles, and mountain bicycles. Utility bicycles are the most common form globally, and comprise the vast majority found in the developing world. City bikes may be individually owned or operated as part of a public bike sharing scheme.
Generally as they are more suitable for urban environments, they focus more on comfort and practicality instead of speed or efficiency. They normally have a slightly curved, roughly planar aligned and elevated handlebar, providing users an upright sitting position. They have fewer gears and they often are heavier than road bicycles. They might have the top central frame bar diagonally aligned for allowing easy mounting in and out and they might have a back or front frame for transport of items. The saddle is typically larger compared with other bicycles and the majority are provided with chain and tire protection against oil or dirt.
History
Bicycles have been promoted for their utilitarian strengths since before they were technically known as bicycles. The dandy horse and the boneshaker were hoped to become an inexpensive utilitarian alternative to horses by their makers. However the inherent danger, cost, discomfort, and restrictive gender roles of the day, kept it popular mainly with wealthy adventurous young men, and mainly for recreation and sport. The development of penny-farthing moved away from the utilitarian goal of earlier forms, with its less stable ride, and difficulty carrying much baggage. It furthered the trend of bicycles to be used by young men, willing to take risks, for sport and recreation. Despite this, we find the earliest mention of working bikes in 1874, in Paris, as couriers, for a newspaper and the stock market riding penny-farthings.It was the introduction of the safety bicycle that was successful for the first time to build a bicycle that worked well for utilitarian purposes, "a poor man's nag". It was this development that was the cause of the bicycle boom of the 1890s. The main use of bicycles during the boom was still sport and recreation, but additionally they were adopted by many professions such as police, postal workers, delivery men, municipal workers and for basic transportation of people of all classes, races, and genders. In the US, after the boom, use changed dramatically from sport and recreation to basic transportation. By 1902, as the boom was coming to an end, nearly all cyclists were cycling for practical purposes. The price of bicycles dropped dramatically, due to increased competition between makers and more price-conscious consumers; profits dried up and many of the cycling manufacturers went out of business. The history is similar in the UK, but there some of the manufacturers were better able to handle the transition to transportation based cycling, even to the point of talking of a second boom due to so many working-class people taking up cycling. Additionally the British makers were able to tap into the developing markets overseas, primarily India, China, and Japan. In countries like the US, the use of utility bicycles all but disappeared until after the Second World War, when a few British and Italian roadster-type bicycles saw a brief upsurge in popularity. Since the Second World War, utility bicycles have remained popular in countries like the Netherlands, China, and much of the developing world.
Technological improvements
Since the 1890s only incremental mechanical advances have taken place for the majority of the world's utility bicycles. In fact many bicycles in Asia still employ rod brakes. One exception to this was the continued development of substitute propulsion systems for utility bicycles in the form of add-on gasoline engines and transmissions. Developed shortly after 1900 in Europe and the United States, motorized utility bicycles surged in popularity in Western Europe after the Second World War. Typically, a small one or two-horsepower, two-cycle engine was fitted with a tire roller-drive mechanism that would convert any standard utility roadster into a motorised bicycle. As they could still be propelled by human power, they were considered as bicycles under most national registration schemes. The motorised utility bicycle or cyclemotor offered greater range, faster commutes, and increased versatility to a large sector of the postwar European consumer market that could not afford expensive automobiles or motorcycles.In 1962, the advent of the Moulton bicycle brought a fresh outlook to the traditional utility concept. Using small, easily transportable frames and wheels as well as suspension, the Moulton was designed to accommodate the increasing public usage of bicycles in concert with other forms of mass transportation. During the 1990s, several bicycle designs were introduced in an attempts to improve on the traditional utility bike. Most of these centered on the use of lightweight frame alloys, new brake and gearing systems, and electronic navigation and monitoring assistance.
Use
Utility bicycles are principally used for short-distance commuting, running errands, shopping, leisure or for transporting goods or merchandise. Utility bicycles may also be seen in postal service, in war, and for employee transportation inside large workplaces. In some countries, entire fleets of utility bicycles may be operated or administered by local or national government agencies as part of a public bike sharing programme.The utility bicycle is the most widely used form of bicycle in many undeveloped parts of the world. While motor vehicles have displaced bicycles for personal transportation in many industrialized and post-industrial nations, rising fuel costs and concerns over the environment have led many people to once again turn to utility bicycles for a variety of daily tasks. In countries where purpose-built utility bikes are unavailable or unsuited to local conditions, many cyclists have acquired hybrid bicycles, road bicycles, mountain bikes, or touring bicycles for commuting and general utility use, often refurbishing older or secondhand models. A few countries, notably China, India, Japan, Netherlands, Denmark and the Flemish Region of Belgium, continue to produce versions of the utility bike. In addition, the Deutsche Post uses a version of a utility bike in most German cities for delivering mail.
Design
Utility bicycles often feature a step-through frame so they can be easily mounted, single speed, or with internal hub gearing, and drum brakes to reduce the need for maintenance, mudguards to keep the rider's clothing clean, a chain guard to prevent skirts or loose trousers from being caught in the chain, a skirt guard to prevent a long coat or skirt catching in the rear wheel or brakes, a center stand kickstand so it can be parked easily, and a basket or pannier rack to carry personal possessions or shopping bags.A traditional type of utility bicycle, the roadster may weigh as much as 16–23 kg. Parts such as frames, wheels/rims, and tires are chosen for strength, safety, and durability rather than high performance. Additionally, utility bikes tend to incorporate fewer technological advances in material design and engineering in comparison to road bicycles, though there are exceptions. In particular, the small-tired Moulton portable utility cycles incorporate advanced engineering with slightly lighter weight.
Most utility bikes feature an upright riding position. The handlebars are almost always curved back and positioned higher than the saddle so that the rider can operate controls without changing their riding posture. The saddle is also placed right above the rear wheel axle instead of the bottom bracket, which makes it more difficult to pedal. Some people add a child seat or a trailer. The utility bike's combination of parts, design, and features provide functionality and comfort at the expense of weight, an adequate compromise when used as originally intended.Image:Gazelle Omafahrrad series -1.jpg|thumb|A vintage omafiets, the Dutch ladies' bicycle
''Stadsfiets'' as a defining term
The Dutch stadsfiets has the full set of features commonly incorporated into a utility bicycle. The Dutch words fiets and stadsfiets mean 'bicycle' and 'city bicycle', respectively. A stadsfiets is considered to be a fully outfitted European city bike, distinguished by the following typical features: upright riding position, fully enclosed chaincase, skirtguard, ring lock, hub gearing, dynamo hub, manually operated small warning bell, and built-in lights.German and Dutch versions of the European city bike are similar, though there are differences.
The English roadster is similar in design, appearance, and intended use. The primary differences are that the continental bicycles tend to have a higher handlebar position for a more upright riding posture, and are more likely to have rod-actuated drum brakes. Because of Great Britain's cultural and trading influence in its former colonies, the roadster can still be seen in local production and use in many countries of the world.
Traditional vs. contemporary design
A traditional-styled European city bike includes a frame made of low-carbon high-tensile steel, black paint with chromed accessories, an opaque skirt guard, bottle dynamo, simple dynamo-powered lights, and either a single-speed or 3-speed internally geared hub.Contemporary city bikes are increasingly found in many European cities, including Amsterdam and Copenhagen. Dutch and Danish-made city bikes often include such features as a clear skirt guard, colors other than black, aluminium alloy or chromoly steel frame, front suspension fork, suspension seatpost, hub dynamo, dynamo lighting with motion-and-darkness detection, magnetic lights, a 7- or 8-speed hub, adjustable kickstand, child seats, and a headlight integrated into the front fork. Newer German models, on the other hand, tend to incorporate a less is more philosophy.
