Snowbiking
Cold-weather biking, cold-weather cycling, or winter biking is the use of a bicycle during months when roads and paths are covered with ice, slush and snow. Cold weather cyclists face a number of challenges in near or below freezing temperatures. Urban commuters on city streets may have to deal with " ow, slush, salt, and sand", which can cause rust and damage to metal bike components. Slush and ice can jam derailleurs. Some cyclists may bike differently in winter, by "slow ngdown on turns and brak nggradually" in icy conditions. Gaining traction on snow and ice-covered roads can be difficult. Winter cyclists may use bikes with front and rear fenders, metal studded winter tires and flashing LED lights. Winter cyclists may wear layers of warm clothes and ear, face, and hand coverings may be worn. Specialized winter bikes called fatbikes, which have wide, oversized tires that are typically inflated with low pressure, are used in snow trail riding and winter bike competitions. Ter ...

Commuting Icebike
Commuting is periodically recurring travel between a place of residence and place of work or study, where the traveler, referred to as a commuter, leaves the boundary of their home community. By extension, it can sometimes be any regular or often repeated travel between locations, even when not work-related. The modes of travel, time taken and distance traveled in commuting varies widely across the globe. Most people in least-developed countries continue to walk to work. The cheapest method of commuting after walking is usually Bicycle commuting, by bicycle, so this is common in low-income countries but is also increasingly practised by people in wealthier countries for environmental, health, and often time reasons. In middle-income countries, motorcycle commuting is very common. The next technology adopted as countries develop is more dependent on location: in more populous, older cities, especially in Eurasia mass transit (rail, bus, etc.) predominates, while in smaller, ...

Surly Bikes
Surly Bikes, or Surly, is a bicycle brand based in Bloomington, Minnesota, United States, that was founded in 1998. It is a division of Quality Bicycle Products, a manufacturer and distributor of bicycles and bicycle parts. Despite sharing a similar name and being headquartered in the U.S. state of Minnesota, Surly Bikes and Surly Brewing Company are separate enterprises, with an agreement between the two companies allowing the bicycle company to display the single word "Surly" on its products. Surly Brewing’s Omar Ansari reached out to Surly Bikes before launching the brewery to make sure there would be no conflict. History The Surly brand was developed in house at the Minnesota-based Quality Bicycle Products in the 1990s as a complement to its other brands, such as Salsa Cycles. At the time, "fatbikes" were emerging on the market for winter use in snowy climates, but they were considered exotic and too expensive to produce. Quality Bicycle Products hoped to standardize pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycling (magazine)
''Bicycling'' is a cycling magazine published by Hearst in Easton, Pennsylvania. __TOC__ History ''Bicycling'' started in 1961 as ''Northern California Cycling Association Newsletter'', a four-page mimeographed newsletter (8 ½ x 14) started by Peter Hoffman. It covered the local bicycle scene and grew quickly as Vol. 1 No. 6 took on a 5 ½ x8 ½ offset printing format in December, 1961. The name was changed to ''American Cycling Newsletter'' with Vol. 3 No. 1 in March, 1964 issue. The name was changed again with Vol. 5 No. 1 in March, 1965 to ''American Cycling''. The size was changed to a larger format with Vol. 5 No. 1 in March, 1966 to 8 ½ x 11. Peter Hoffman sold the magazine to Leete Publications in August 1968 but stayed on as an editor until late 1969. The last ''American Cycling'' titled magazine was the Nov. 1968 issue, Vol. 7 No. 8. The name was changed to ''Bicycling!'' with the Dec 1968 Issue Vol 7 No 9. For three months following the name change, "American Cyc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fat Bike
A fatbike (also called fat bike, fat tire, fat-tire bike, or snow bike) is an off-road bicycle built to accommodate oversized tyres, typically or larger and rims or wider, designed for low ground pressure to allow riding on soft, unstable terrain, such as snow, sand, bogs and mud. Fatbikes are built around frames with wide forks and stays to accommodate the space required to fit these wide rims and tires. The wide tires can be used with inflation pressures as low as to allow for a smooth ride over rough obstacles. A rating of is suitable for most riders. Fatbikes were developed for use in snow or sand, but are capable of traversing diverse terrain types including snow, sand, desert, bogs, mud, pavement, or traditional mountain biking trails. History Early versions of fat-tired bikes were probably built as long ago as the early 1900s but modern versions were not developed until the 1980s. An early example is the custom three-wheeled in-line longtail-style bike with fat tires ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Antarctic Cycling Expeditions
Antarctic cycling expeditions were made possible with the development of fatbikes: fat tired bicycles designed for riding in snow and sand. Expeditions Expeditions in descending order of distance cycled. Doug Stoup was the first person to undertake a cycling expedition in Antarctica. In January 2003 he rode on a specially designed "ice bike" around the Patriot Hills. In 2012, Helen Skelton became the first person to reach the South Pole using a bicycle. The bike was custom built for her trip with 8-inch-wide (20 cm) tires. She also used skis and a kite to help her pull a sled containing of supplies. She covered by kite ski, by bike and by cross-country ski Cross-country skiing is a form of skiing whereby skiers traverse snow-covered terrain without use of ski lifts or other assistance.

Bicycle Messenger
Bicycle messengers (also known as bike or cycle couriers) are people who work for courier companies (also known as messenger companies) carrying and delivering items by bicycle. Bicycle messengers are most often found in the central business districts of metropolitan areas. Courier companies use bike messengers because bicycle travel is less subject to unexpected holdups in city traffic jams, and is not deterred by parking limitations, fees or fines in high-density development that can hinder or prevent delivery by motor vehicle, thereby offering a predictable delivery time. Because bicycle thefts are prevalent in many cities, a lock to secure the bike during deliveries is essential. U-locks are also popular. Messengers typically carry basic tools, weather-proof clothing and a street map. It is also common for messengers to carry storage clipboards for manifests, receipts, and/or other logistic documents.

Balaclava (clothing)
A balaclava, also called a ski mask, is a form of cloth headgear designed to expose only part of the face, usually the eyes and mouth. Depending on style and how it is worn, only the eyes, mouth and nose, or just the front of the face are unprotected. Versions with enough of a full face opening may be rolled into a hat to cover the Crown (anatomy), crown of the head or folded down as a collar around the neck. It is commonly used in alpine skiing and snowboarding. History Similar styles of headgear were known in the 19th century as the ''Uhlan cap'' worn by Polish and Prussian soldiers, and the ''Knit cap, Templar cap'' worn by outdoor sports enthusiasts. The name comes from their use at the 1854 Battle of Balaclava during the Crimean War, referring to the town of Balaklava near Sevastopol in Crimea, where British troops there wore knitted headgear to keep warm. Handmade balaclavas were sent over to the British Army, British troops to help protect them from the bitter cold weath ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windchill
Wind chill (popularly wind chill factor) is the sensation of cold produced by the wind for a given ambient air temperature on exposed skin as the air motion accelerates the rate of heat transfer from the body to the surrounding atmosphere. Its values are always lower than the air temperature in the range where the formula is valid. When the apparent temperature is higher than the air temperature, the heat index is used instead. Explanation A surface loses heat through Thermal conduction, conduction, evaporation, convection, and radiation. The rate of convection depends on both the difference in temperature between the surface and the fluid surrounding it and the velocity of that fluid with respect to the surface. As convection from a warm surface heats the air around it, an insulating boundary layer of warm air forms against the surface. Moving air disrupts this boundary layer, or epiclimate, carrying the warm air away, thereby allowing cooler air to replace the warm air agains ...

Ice Biker
Ice is water that is freezing, frozen into a solid state, typically forming at or below temperatures of 0 °Celsius, C, 32 °Fahrenheit, F, or 273.15 Kelvin, K. It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice. As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. Depending on the presence of Impurity, impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less Opacity (optics), opaque bluish-white color. Virtually all of the ice on Earth is of a Hexagonal crystal system, hexagonal Crystal structure, crystalline structure denoted as ''ice Ih'' (spoken as "ice one h"). Depending on temperature and pressure, at least nineteen phases of ice, phases (Sphere packing, packing geometries) can exist. The most common phase transition to ice Ih occurs when liquid water is cooled below (, ) at standard atmospheric pressure. When water is coo ...
