Cycling ACT

Cycling, also, when on a two-wheeled bicycle, called bicycling or biking, is the use of cycles for transport, recreation, exercise or sport. People engaged in cycling are referred to as "cyclists", "bicyclists", or "bikers". Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent and similar human-powered vehicles (HPVs).

Bicycles were introduced in the 19th century and now number approximately one billion worldwide. They are the principal means of transportation in many parts of the world, especially in densely populated European cities.

Cycling is widely regarded as an effective and efficient mode of transportation optimal for short to moderate distances.

Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a reduced consumption of fossil fuels, less air and noise pollution, reduced greenhouse gas emissions, and greatly reduced traffic congestion. These have a lower financial cost for users as well as for society at large (negligible damage to roads, less road area required). By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve.

In addition, cycling provides a variety of health benefits and reduces the risk of cancers, heart disease, and diabetes that are prevalent in sedentary lifestyles. Cycling on stationary bikes have also been used as part of rehabilitation for lower limb injuries, particularly after hip surgery. Individuals who cycle regularly have also reported mental health improvements, including less perceived stress and better vitality.

Among the disadvantages of cycling are the requirement of bicycles (excepting tricycles or quadricycles) for the rider to have certain level of basic skill in order to remain upright, the reduced protection in crashes in comparison to motor vehicles, often longer travel time (except in densely populated areas), vulnerability to weather conditions, difficulty in transporting passengers, and the fact that a basic level of fitness is required for cycling moderate to long distances.

History

Cycling quickly became an activity after bicycles were introduced in the 19th century. Today, over 50 percent of the human population knows how to ride a bike.

War

The bicycle has been used as a method of reconnaissance as well as transporting soldiers and supplies to combat zones. In this it has taken over many of the functions of horses in warfare. In the Second Boer War, both sides used bicycles for scouting. In World War I, France, Germany, Australia and New Zealand used bicycles to move troops. In its 1937 invasion of China, Japan employed some 50,000 bicycle troops, and similar forces were instrumental in Japan's march or "roll" through Malaya in World War II. Germany used bicycles again in World War II, while the British employed airborne "Cycle-commandos" with folding bikes.

In the Vietnam War, communist forces used bicycles extensively as cargo carriers along the Ho Chi Minh Trail.

The last country known to maintain a regiment of bicycle troops was Switzerland, which disbanded its last unit in 2003.

Equipment

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 of the road and easing steering at low speeds. Utility bicycles tend to be equipped with accessories such as mudguards, pannier racks and lights, which extends their usefulness on a daily basis. Since the bicycle is so effective as a means of transportation, various companies have developed methods of carrying anything from the weekly shop to children on bicycles. Certain countries rely heavily on bicycles and their culture has developed around the bicycle as a primary form of transport. In Europe, Denmark and the Netherlands have the most bicycles per capita and most often use bicycles for everyday transport.

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, making use of stronger muscles (particularly the gluteus maximus) and reducing air resistance at high speed.

The price of a new bicycle can range from US$50 to more than US$20,000 (the highest priced bike in the world is the custom Madone by Damien Hirst, sold at US$500,000), depending on quality, type and weight (the most exotic road bicycles can weigh as little as 3.2 kg (7 lb)). However
UCI
regulations stipulate a legal race bike cannot weigh less than 6.8 kg (14.99 lbs). Being measured for a bike and taking it for a test ride are recommended before buying.

The drivetrain components of the bike should also be considered. A middle grade dérailleur is sufficient for a beginner, although many utility bikes are equipped with hub gears. If the rider plans a significant amount of hillclimbing, a triple-chainrings crankset gear system may be preferred. Otherwise, the relatively lighter, simpler, and less expensive double chainring is preferred, even on high-end race bikes. Much simpler fixed wheel bikes are also available.

Many road bikes, along with mountain bikes, include clipless pedals to which special shoes attach, via a cleat, enabling the rider to pull on the pedals as well as push. Other possible accessories for the bicycle include front and rear lights, bells or horns, child carrying seats, cycling computers with GPS, locks, bar tape, fenders (mud-guards), baggage racks, baggage carriers and pannier bags, water bottles and bottle cages.

For basic maintenance and repairs cyclists can carry a pump (or a CO₂ cartridge), a puncture repair kit, a spare inner tube, and tire levers and a set of allen keys. Cycling can be more efficient and comfortable with special shoes, gloves, and shorts. In wet weather, riding can be more tolerable with waterproof clothes, such as cape, jacket, trousers (pants) and overshoes and high-visibility clothing is advisable to reduce the risk from motor vehicle users.

Items legally required in some jurisdictions, or voluntarily adopted for safety reasons, include bicycle helmets, generator or battery operated lights, reflectors, and audible signalling devices such as a bell or horn. Extras include studded tires and a bicycle computer.

Bikes can also be heavily customized, with different seat designs and handle bars, for example.

Skills

Many schools and police departments run educational programs to instruct children in bicycle handling skills, especially to introduce them to the rules of the road as they apply to cyclists. In some countries these may be known as bicycle rodeos, or operated as schemes such as Bikeability in the UK. Education for adult cyclists is available from organizations such as the League of American Bicyclists.

Beyond simply riding, another skill is riding efficiently and safely in traffic. One popular approach to riding in motor vehicle traffic is vehicular cycling, occupying road space as car does. Alternately, in countries such as Denmark and the Netherlands, where cycling is popular, cyclists are often segregated into bike lanes at the side of, or more often separate from, main highways and roads. Many primary schools participate in the national road test in which children individually complete a circuit on roads near the school while being observed by testers.

Infrastructure

Cyclists, pedestrians and motorists make different demands on road design which may lead to conflicts. Some jurisdictions give priority to motorized traffic, for example setting up one-way street systems, free-right turns, high capacity roundabouts, and slip roads. Others share priority with cyclists so as to encourage more cycling by applying varying combinations of traffic calming measures to limit the impact of motorized transport, and by building bike lanes, bike paths and cycle tracks. The provision of cycling infrastructure varies widely between cities and countries, particularly since cycling for transportation almost entirely occurs in public streets. And, the development of computer vision and street view imagery has provided significant potential to assess infrastructure for cyclists.

In jurisdictions where motor vehicles were given priority, cycling has tended to decline while in jurisdictions where cycling infrastructure was built, cycling rates have remained steady or increased. Occasionally, extreme measures against cycling may occur. In Shanghai, where bicycles were once the dominant mode of transport, bicycle travel on a few city roads was banned temporarily in December 2003.

In areas in which cycling is popular and encouraged, cycle-parking facilities using bicycle stands, lockable mini-garages, and patrolled cycle parks are used in order to reduce theft. Local governments promote cycling by permitting bicycles to be carried on public transport or by providing external attachment devices on public transport vehicles. Conversely, an absence of secure cycle-parking is a recurring complaint by cyclists from cities with low modal share of cycling.

Extensive cycling infrastructure may be found in some cities. Such dedicated paths in some cities often have to be shared with in-line skaters, scooters, skateboarders, and pedestrians. Dedicated cycling infrastructure is treated differently in the law of every jurisdiction, including the question of liability of users in a collision. There is also some debate about the safety of the various types of separated facilities.

Bicycles are considered a sustainable mode of transport, especially suited for urban use and relatively shorter distances when used for transport (compared to recreation). Case studies and good practices (from European cities and some worldwide examples) that promote and stimulate this kind of functional cycling in cities can be found at Eltis, Europe's portal for local transport.

A number of cities, including Paris, London and Barcelona, now have successful bike hire schemes designed to help people cycle in the city. Typically these feature utilitarian city bikes which lock into docking stations, released on payment for set time periods. Costs vary from city to city. In London, initial hire access costs £2 per day. The first 30 minutes of each trip is free, with £2 for each additional 30 minutes until the bicycle is returned.

In the Netherlands, many roads have one or two separate cycleways alongside them, or cycle lanes marked on the road. On roads where adjacent bike paths or cycle tracks exist, the use of these facilities is compulsory, and cycling on the main carriageway is not permitted. Some 35,000 km of cycle-track has been physically segregated from motor traffic, equal to a quarter of the country's entire 140,000 km road network. A quarter of all the trips in the country made on bicycles, one quarter of them to work. Even the prime minister is going to work by bicycle, when weather permits. This saves the life of 6,000 citizens per year, prolong the life expectancy by 6 months, save the country 20 million dollars per year, and prevent 150 grams of to be emitted per kilometer of cycling, on each bicycle.

Types

Utility

Utility cycling refers both to cycling as a mode of daily commuting transport as well as the use of a bicycle in a commercial activity, mainly to transport goods, mostly accomplished in an urban environment.

The postal services of many countries have long relied on bicycles. The British Royal Mail first started using bicycles in 1880; now bicycle delivery fleets include 37,000 in the UK, 25,700 in Germany, 10,500 in Hungary and 7000 in Sweden. In Australia, Australia Post has also reintroduced bicycle postal deliveries on some routes due to an inability to recruit sufficient licensed riders willing to use their uncomfortable motorbikes. The London Ambulance Service has recently introduced bicycling paramedics, who can often get to the scene of an incident in Central London more quickly than a motorized ambulance.

The use of bicycles by police has been increasing, since they provide greater accessibility to bicycle and pedestrian zones and allow access when roads are congested. In some cases, bicycle officers have been used as a supplement or a replacement for horseback officers.

Bicycles enjoy substantial use as general delivery vehicles in many countries. In the UK and North America, as their first jobs, generations of teenagers have worked at 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 cycle couriers who deliver documents and small packages. In India, many of Mumbai's Dabbawalas 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.

Recreational

Bicycle touring

Bicycles are used for recreation at all ages. Bicycle touring, also known as cyclotourism, involves touring and exploration or sightseeing by bicycle for leisure. Bicycle tourism has been one of the most popular sports for recreational benefit. A brevet or randonnée is an organized long-distance ride.

One popular Dutch pleasure is the enjoyment of relaxed cycling in the countryside of the Netherlands. The land is very flat and full of public bicycle trails and cycle tracks where cyclists are not bothered by cars and other traffic, which makes it ideal for cycling recreation. Many Dutch people subscribe every year to an event called '' fietsvierdaagse'' â€” 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 and imposes a 90-hour time limit. Similar if smaller institutions exist in many countries.

A study conducted in Taiwan improved the environmental quality for bicyclist tourists which demonstrated greater health benefits in tourists and even in natives. The number of bicyclists in Taiwan increased from 700,000 in 2008 to 5.1 million in 2017. Thus, this resulted in more and safer bicycle routes to be established. When cycling, cyclists take into account the safety on the road, bicycle lanes, smooth roads, diverse scenery, and ride length. Thus, the environment plays a huge role in people's decision factor to utilize bicycle touring more. This study utilized many questionnaires and conducted statistical analysis to come up with the conclusion of cyclists' top 5 factors that they consider before making a decision to bike are: safety, lighting facility, design of lanes, the surrounding landscape, and how clean the environment is. Thus, after improving these 5 factors, they found much more recreational benefits to bicycle tourism.

Organized rides

Many cycling clubs 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.

Most organized rides, for example cyclosportives (or gran fondos), Challenge Rides or reliability trials, and 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 several different routes, sorted by mileage, and with a certain number of rest stops that usually include refreshments, first aid and maintenance tools. Routes can vary by as much as .

Some organized rides are entirely social events. One example is the monthly San Jose Bike Party which can reach attendance of one to two thousand riders in Summer months.

Mountain

Mountain biking began in the 1970s, originally as a downhill sport, practised on customized cruiser bicycles around Mount Tamalpais. Most mountain biking takes place on dirt roads, trails and in purpose-built parks. Downhill mountain biking has just evolved in the recent years and is performed at places such as Whistler Mountain Bike Park. Slopestyle, a form of downhill, is when riders do tricks such as tailwhips, 360s, backflips and front flips.
There are several disciplines of mountain biking besides downhill, including: cross country (often referred to as XC), all mountain, trail, free ride, and newly popular enduro.

In 2020, due to COVID-19, mountain bikes saw a surge in popularity in the US, with some vendors reporting that they were sold out of bikes under US$1000.

Other

The Marching and Cycling Band HHK from Haarlem (the Netherlands) is one of the few marching bands around the world which also performs on bicycles.

Racing

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 the United Kingdom, 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.

In 1899, Charles Minthorn Murphy became the first man to ride his bicycle a mile in under a minute (hence his nickname, Mile-a-Minute Murphy), which he did by drafting a locomotive at New York's Long Island.

As the bicycle evolved its various forms, different racing formats developed. Road races may involve both team and individual competition, and are contested in various ways. They range from the one-day road race, criterium, and time trial to multi-stage events like the Tour de France and its sister events which make up cycling's Grand Tours. Recumbent bicycles were banned from bike races in 1934 after Marcel Berthet set a new hour record in his ''Velodyne streamliner'' (49.992 km on 18 November 1933). Track bicycles are used for track cycling in Velodromes, while cyclo-cross races are held on outdoor terrain, including pavement, grass, and mud. Cyclocross races feature man-made features such as small barriers which riders either bunny hop
