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 ...

South Pole Traverse
The South Pole Traverse, also called the South Pole Overland Traverse, is an approximately flagged route over compacted snow and ice in Antarctica that links McMurdo Station on the coast to the Amundsen–Scott South Pole Station, both operated by the National Science Foundation of the United States. It was constructed by levelling snow and filling in crevasses; flags mark its route from McMurdo Station across the Ross Ice Shelf to the Leverett Glacier, where the route ascends to the polar plateau and on to the South Pole. Route description After four years of development, the trail was fully traversed for the first time in 2005, with Caterpillar and Case Corp. tractors pulling specialized sleds to deliver fuel and cargo to the South Pole in about 40 days. The return trip to McMurdo Station, with less fuel and cargo, is substantially quicker. Construction started during the 2002/03 southern summer field season. It was finished in the 2005/2006 southern summer. The McMur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Bike
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 othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Bicycle
An electric bicycle (e-bike, eBike, etc.) is a motorized bicycle with an integrated electric motor used to assist propulsion. Many kinds of e-bikes are available worldwide, but they generally fall into two broad categories: bikes that assist the rider's pedal-power (i.e. pedelecs) and bikes that add a throttle, integrating moped-style functionality. Both retain the ability to be pedaled by the rider and are therefore not electric motorcycles. E-bikes use rechargeable batteries and typically are motor-powered up to . High-powered varieties can often travel more than . E-bike use is growing in some markets, as they are seen as an eco-friendly and healthy alternative to cars, fossil fuel-powered mopeds and small motorcycles, and a less physically intense alternative to conventional bicycles. Depending on local laws, many e-bikes (e.g., ''pedelecs'') are legally classified as bicycles rather than mopeds or motorcycles. This exempts them from the more stringent laws regarding t ...

Outline Of Cycling
:''This article is an outline about the activity of cycling. For an outline about bicycles themselves, see outline of bicycles.'' :The following ''outline'' is provided as an overview of, as well as a topical guide to cycling: Cycling, also called bicycling or biking, is the activity of using / riding bicycles, (at least partially) human-powered, wheeled vehicles (typically by foot pedalling), for purposes including transport, recreation, social interaction, exercise, sport, therapy, other purposes, or any combination thereof. Persons engaged in cycling are called cyclists, bikers, or sometimes bicyclists. They typically either dress for where they are going, or for the cycling, sometimes having another set of clothing with them, or arranged. Apart from regular two-wheeled bicycles, cycling also includes riding unicycles, tricycles, quadricycles, and other similar human-powered wheeled vehicles (HPVs). Some bicycles are sold with (electric) motors (e-bikes), or ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctica 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 ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...
