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 "ea face, and han coverings may be used. 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. Termi ...

Commuting Icebike
Commuting is periodically recurring travel between one's 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 by bicycle, so this is common in low-income countries, but is also increasingly practised by people in wealthier countries for environmental and health 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, younger cities, and larg ...

Mountain Bikes
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimised for topography and application (e.g., steep climbing or fast descending). Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper posts can be installed to allow the rider to quickly adjust the seat height (an elevated seat position is more effective for pedaling, but poses a hazard in aggressive maneuvers). Mountain bikes are generally specialized for use on mountain trails, single track, fire roads, and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 par ... [...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.

Fat Bike
A fatbike (also called fat bike, fat tire, fat-tire bike, or snow bike) is an off-road bicycle with oversized tires, 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 wide rims required to fit these 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 the majority of riders. Fatbikes were invented for use in snow and sand, but are capable of traversing diverse terrain types including snow, sand, desert, bogs, mud, pavement, or traditional mountain biking trails. The sport is sometimes referred to as fatbiking or fat-tire biking. History Although early versions of fat-tired bikes were probably built on a limited basis as long ago as the early 1900s, the first modern versions were not developed until the 1980s ...

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 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 where skiers rely on their own locomotion to move across snow-covered terrain, rather than using ski lifts or other forms of assistance. Cross-country skiing is widely practiced as a sport and recreation .... Some of Skelton's claims have been challenged. In December 2012, Eric La ...

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. History Almost immediately after the development of the pedal-driven velocipede in the 1860s, people began to use the bicycle for delivery purposes. David V. Herlihy's 2004 book on the early history of the bicycle contains several references to bicycle messengers working during the late 19th century, including a description of couriers employed by the Paris stock exchange in the 1870s.

Balaclava (clothing)
A balaclava, also known as a balaclava helmet or 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 of the head or folded down as a collar around the neck. History Similar styles of headgear were known in the 19th century as the ''Uhlan cap'' worn by Polish and Prussian soldiers, and the ''Templar cap'' worn by outdoor sports enthusiasts. The name comes from their use at the Battle of Balaclava during the Crimean War of 1854, referring to the town near Sevastopol in the Crimea, where British troops there wore knitted headgear to keep warm. Handmade balaclavas were sent over to the British troops to help protect them from the bitter cold weather. British troops required this aid, as their own supplies (warm clothing, w ...

Windchill
Wind chill or windchill (popularly wind chill factor) is the lowering of body temperature due to the passing-flow of lower-temperature air. Wind chill numbers are always lower than the air temperature for values 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 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, allowing for cooler air to replace the warm air against the surface. The faster the wind speed, the more readily the surface cools. Alternative approaches Many formulas exist for wind chill beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
