<!--In many countries, the most commonly used [[vehicle]] for [[road transport]] is a [[utility bicycle]]. These have frames with relaxed geometry, protecting the rider from shocks from the road, and easing steering at low speeds.

Road bikes tend to have a more upright shape and a shorter wheelbase, which make the bike more mobile but harder to ride slowly. The design, coupled with low or dropped handlebars, requires the rider to bend forward more, which reduces air resistance at high speed.

 

 

The [[bicycle#Drivetrain|drivetrain]] components of the bike should also be considered. A middle grade [[dérailleur]] is sufficient for a beginner, although many utility bikes come equipped with [[hub gear]]s. If the rider plans a significant amount of [[Hillclimbing (cycling)|hillclimbing]], a triple-[[crankset|crank]] (three chainrings) front [[bicycle gearing|gear system]] may be preferred. Otherwise, the relatively lighter and less expensive two chainrings may be better.

In the Netherlands bicycle paths are widespread and are (in the cities) closed to scooters. Cyclists in the Netherlands are well protected as the law assumes the stronger participant (i.e. the car driver) is guilty until proved innocent (ie is the guilty party in all accidents involving weaker traffic unless evidence of the opposite is provided). Furthermore, drivers know to expect bikes, which are plentiful and treat traffic rules as guidelines to be ignored at will (increasingly common in the UK, also). Due to these issues the number of car-bike collisions with serious consequences is not alarmingly high in the Netherlands

Bicycles enjoy substantial use as general delivery vehicles in many countries. In the UK and North America, generations of teenagers have got their first jobs delivering newspapers by bicycle. London has many delivery companies that use bicycles with trailers. Most cities in the West, and many outside it, support a sizeable and visible industry of [[Bicycle messenger|cycle couriers]] who deliver documents and small packages. In India, many of [[Mumbai]]'s [[Dabbawala]]s use bicycles to deliver home cooked lunches to the city’s workers. In [[Bogotá]], [[Colombia]] the city’s largest bakery recently replaced most of its delivery trucks with bicycles. Even the car industry uses bicycles. At the huge [[Mercedes-Benz]] factory in [[Sindelfingen]], Germany workers use bicycles, color-coded by department, to move around the factory.

One popular [[Netherlands|Dutch]] pleasure is the enjoyment of relaxed cycling in the [[rural|countryside]] of the Netherlands. The land is very flat and full of public [[Segregated cycle facilities|bicycle trails]] where cyclists aren't bothered by [[automobile|cars]] and other traffic, which makes it ideal for cycling recreation. Many [[Dutch people]] subscribe every [[year]] to an event called ''[[fietsvierdaagse]]'' &mdash; four days of organised cycling through the local environment. [[Paris-Brest-Paris]] (PBP), which began in 1891, is the oldest bicycling event still run on a regular basis on the open road, covers over 1200 km and imposes a 90-hour time limit. Similar if smaller institutions exist in many countries.

Many [[cycling club]]s hold organized rides in which bicyclists of all levels participate. The typical organized ride starts with a large group of riders, called the mass, bunch or even [[peloton]]. This will thin out over the course of the ride. Many riders choose to ride together in groups of the same skill level to take advantage of [[drafting (racing)|drafting]].

Most organized rides, for example [[Cyclosportive]]s, [[Challenge riding|Challenge Rides]] or [[reliability trial]]s, and [[Hillclimbing (cycling)|hill climbs]] include registration requirements and will provide information either through the mail or online concerning start times and other requirements. Rides usually consist of 25, 50 and 100 mile routes, each with a certain number of rest stops that usually include refreshments, first aid and maintenance tools.

 

[[Mountain biking]] grew in the late 20th century, including recreation and racing. It emphasises riding special cycles with high gear ratios over rough paths, special obstacle courses or directly cross country. While very popular as a sport, it has also been criticised for damaging the countryside.

Shortly after the introduction of bicycles, competitions developed independently in many parts of the world. Early races involving [[boneshaker]] style bicycles were predictably fraught with injuries. Large races became popular during the 1890s "Golden Age of Cycling", with events across Europe, and in the U.S. and Japan as well. At one point, almost every major city in the US had a [[velodrome]] or two for [[track racing]] events. However since the middle of the 20th century cycling has become a minority sport in the US whilst in Continental Europe it continues to be a major sport, particularly in France, Belgium, Italy and Spain. The most famous of all bicycle races is the [[Tour de France]]. This began in 1903, and continues to capture the attention of the sporting world.
