Fatbike
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. ...

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] |
Bicycle Tire
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically, the second largest source, after wind resistance (air drag), of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle. Bicycle tires are also used on unicycles, tricycles, quadracycles, tandem bicycles, hand cycles, bicycle trailers, and trailer bikes. History The first bicycle "tires" were iron bands on the wooden wheels of velocipedes. These ... [...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 oth ... [...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 ...

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 ...

Nordic Countries
The Nordic countries (also known as the Nordics or ''Norden''; lit. 'the North') are a geographical and cultural region in Northern Europe and the North Atlantic. It includes the sovereign states of Denmark, Finland, Iceland, Norway and Sweden; the autonomous territories of the Faroe Islands and Greenland; and the autonomous region of Åland. The Nordic countries have much in common in their way of life, history, religion and social structure. They have a long history of political unions and other close relations but do not form a singular entity today. The Scandinavist movement sought to unite Denmark, Norway and Sweden into one country in the 19th century. With the dissolution of the union between Norway and Sweden (Norwegian independence), the independence of Finland in the early 20th century and the 1944 Icelandic constitutional referendum, this movement expanded into the modern organised Nordic cooperation. Since 1962, this cooperation has been based on the Helsi ... [...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 ...
