Bicyclist
Cycling, also known as bicycling or biking, is the activity of riding a bicycle or other types of pedal-driven human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles. Cycling is practised around the world for purposes including transport, recreation, exercise, and competitive sport. History Cycling became popularized in Europe and North America in the latter part and especially the last decade of 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' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cycling Helmet
A bicycle helmet is a type of helmet designed to attenuate impacts to the head of a cyclist in collisions while minimizing side effects such as interference with peripheral vision. History History of designs A cycle helmet should generally be light in weight and provide ample ventilation because cycling can be an intense aerobic activity which significantly raises body temperature, and the head in particular needs to be able to regulate its temperature. The dominant form of the helmet up to the 1970s was the "hairnet" style, an open construction made of rubber bars covered in leather. This offered acceptable protection from scrapes and cuts, but only minimal impact protection, and was mainly used by racing cyclists. More widespread use of helmets began in the US in the 1970s. After many decades when bicycles were regarded largely as children's toys, many American adults took up cycling during and after the bike boom of the 1970s. Two of the first modern bicycl ...

Bicycle
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered transport, human-powered or motorized bicycle, motor-assisted, bicycle pedal, pedal-driven, single-track vehicle, with two bicycle wheel, wheels attached to a bicycle frame, frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century there were more than 1 billion bicycles. There are many more bicycles than cars. Bicycles are the principal Mode of transport, means of transport in many regions. They also provide a popular form of recreation, and have been adapted for use as Toy, children's toys. Bicycles are used for Physical fitness, fitness, Military bicycle, military and Police bicycle, police applications, Bicycle messenger, courier services, Cycle sport, bicycle racing, and artistic cycling.

Tricycles
A tricycle, sometimes abbreviated to trike, is a human-powered (or gasoline or electric motor powered or assisted, or gravity powered) three-wheeled vehicle. Some tricycles, such as cycle rickshaws (for passenger transport) and freight trikes, are used for commercial purposes, especially in the developing world, particularly Africa and Asia. In the West, adult-sized tricycles are used primarily for recreation, shopping, and exercise. Tricycles are favoured by children, the disabled, and senior adults for their apparent stability versus a bicycle; however a conventional trike may exhibit poor dynamic lateral stability, and the rider should exercise appropriate operating caution when cornering (e.g., with regard to speed, rate of turn, slope of surface) and operating technique (e.g., leaning the body 'into' the turn) to avoid tipping the trike over. Designs such as recumbents or others which place the rider lower relative to the wheel axles have a lower centre of gravity, and ...

Exercise
Exercise or workout is physical activity that enhances or maintains fitness and overall health. It is performed for various reasons, including weight loss or maintenance, to aid growth and improve strength, develop muscles and the cardiovascular system, prevent injuries, hone athletic skills, improve health, or simply for enjoyment. Many people choose to exercise outdoors where they can congregate in groups, socialize, and improve well-being as well as mental health. In terms of health benefits, usually, 150 minutes of moderate-intensity exercise per week is recommended for reducing the risk of health problems. At the same time, even doing a small amount of exercise is healthier than doing none. Only doing an hour and a quarter (11 minutes/day) of exercise could reduce the risk of early death, cardiovascular disease, stroke, and cancer. Classification Physical exercises are generally grouped into three types, depending on the overall effect they have on the hum ...

Ho Chi Minh Trail
The Ho Chi Minh Trail (), also called Annamite Range Trail () was a Military logistics, logistical network of roads and trails that ran from North Vietnam to South Vietnam through the kingdoms of Kingdom of Laos, Laos and Cambodia (1953–1970), Cambodia. The system provided support, in the form of manpower and materiel, to the Viet Cong (or "VC") and the People's Army of Vietnam (PAVN), during the Vietnam War. Construction for the network began following the North Vietnamese invasion of Laos in July 1959. At the time it was believed to be the main supply route, however it later transpired that the Sihanouk Trail which ran through Cambodia was handling significantly more material. It was named by the U.S. after the North Vietnamese leader Ho Chi Minh, Hồ Chí Minh. The origin of the name is presumed to have come from the First Indochina War, when there was a Viet Minh maritime logistics line called the "Route of Ho Chi Minh", and shortly after late 1960, as the present trail d ...

Cycling Kit
In competitive cycling, the kit (or uniform) is the standard equipment and attire worn specifically by athletes participating in the sport. The outfits differ from the clothes worn in other forms of cycling, such as commuting and recreational cycling (for which people are likely to wear ordinary street clothes,, , perhaps with a coat or rain cape). Competitive kit uses technical and performance materials and features to improve efficiency and comfort. The UCI specify the kit and the design the riders use. Cycling kits have evolved significantly since the early days of the sport when participants wore wool jerseys. Recent advances in manufacturing and technology have enabled lighter, more comfortable, colourful and complex designs to be made. Cycling kits nowadays are made primarily with synthetic materials, such as Lycra, which conforms to the body, thereby reducing drag by eliminating loose fabric as well as increase in comfort.

Lycra
Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity (physics), elasticity. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont. Name The name ''spandex'', which is an anagram of the word "expands", is the preferred name in North America. In continental Europe, it is referred to by variants of ''elastane''. It is primarily known as ''Lycra'' in the UK, Ireland, Portugal, Spain, Latin America, Australia, and New Zealand. Brand names for spandex include Lycra (made by The Lycra Company, previously a division of Invista, DuPont Textiles and Interiors), Elaspan (The Lycra Company), Acepora (Taekwang Group), Creora (Hyosung), INVIYA (Indorama Corporation), ROICA and Dorlastan (Asahi Kasei), Linel (Fillattice), and ESPA (Toyobo). Production Unlike many other synthetic fibers, spandex cannot be melt-processed because the polymer degrades upon melting. Spandex fibers are produced by several Spinning_(p ...

Cycling Gloves
Cycling gloves are gloves designed for cycling. They may provide warmth, comfort and protection. Basic functionality Warmth Gloves are frequently used to keep the hands warm, a function that is particularly necessary when cycling in cold weather. The design of most modern bicycles is such that the rider's hands remain on the Bicycle handlebar, handlebars while cycling, a position that leaves them exposed to weather. The hands are also relatively inactive, and do not have a great deal of muscle mass, which also contributes to the possibility of chill. Gloves are therefore vital for Thermal insulation, insulating the hands from cold, wind, and evaporative cooling while riding a bicycle. Grip In warm weather, sweat from cyclists' hands can cause difficulty maintaining control over the bicycle by making handlebars slippery and difficult to hold without increased hand tension (which can cause further issues and numbness). Cycling gloves, some designed without full finger cov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycling Jersey
A cycling jersey is a specialised jersey for cycling. The cycling jersey used to be made of wool since the inception of cycling as a sport in the early 1900s, while contemporary jerseys have evolved into technical sportswear that is lightweight, fitted, made of synthetic and moisture-wicking fabric. A specialised cycling jersey for the road discipline features the following unique characteristics: * A longer cut in the back to accommodate the bent-over cycling position * Pockets on the back panel to prevent spill * Silicone grippers at the hem to prevent the jersey from moving up the body while cycling * Full length zip to allow for ventilation * Tight-fitting cut to eliminate loose fabric and reduce air resistance * Moisture-wicking material to keep the cyclist cooler and more comfortable Cycling jerseys are available in various cuts. For instance, a loose 'club cut' offering relaxed fit for recreational cyclists, and a form-fitting 'race cut' featuring a tailored fit th ...
