a Dutch utility bicycle
A utility bicycle (aka ute bicycle[citation needed]) is a bicycle designed for practical transportation, as opposed to "sport bicycles" which are primarily designed for recreation and competition, such as touring bicycles, racing bicycles, sport/training bicycles, and mountain bicycles.

Utility bikes are somewhat similar in purpose, though not in design, to the hybrid bicycle, particularly its subvariants, including the modern city bike and the commuter bike. They are used for short-distance commuting, running errands, shopping, or for transporting goods or merchandise. Utility bikes may also be seen in courier service, in war, and for personal transportation inside large workplaces (factories, warehouses, airports, movie studio lots, etc.). Utility bicycles often feature a step-through frame so they can be easily mounted, hub gears 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 skirt catching in the rear brakes, a kickstand so it can be parked anywhere, and a basket or pannier rack to carry personal possessions or shopping bags. In this guise, they are frequently known as roadsters.
Utility bicycles are typically much heavier than bicycles designed primarily for sport or recreation. The traditional hub-geared English or African utility roadster may weigh as much as 35 to 50 pounds (16 - 23kg). Parts such as frames, rims/wheels, 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 sport bicycles, though there are exceptions. In particular, the small-tired Moulton portable utility cycles incorporate advanced engineering with relatively light weight.

Utility tricycles in Changping District, Beijing
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 his or her riding posture. 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 (relatively flat terrain for short distances).
The utility bicycle, usually seen in the form of the heavy hub-geared English or African roadster or European city bike, 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 the Netherlands, Denmark and the Flemish Region of Belgium, continue to produce versions of the heavy utility bike or roadster. In addition, the Deutsche Post uses a version of a utility bike in most German cities for delivering mail.
