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] |
South Pole Traverse
The South Pole Traverse, also called the South Pole Overland Traverse (SPoT), or McMurdo–South Pole Highway 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. It was constructed between 2002 and end of 2005, when it opened for the first time; it has gained several names and has been called the southernmost road in the world. Although the South Pole base is about a three-hour flight by LC-130 from McMurdo, the overland traverse can deliver massive amounts of cargo including of fuel and of cargo each year. These are carried by land trains (aka convoys) of tracked haulers an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunting
Hunting is the Human activity, human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species (commonly called a culling#Wildlife, cull). Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a ...

Reverse Trike
A three-wheeler is a vehicle with three wheels. Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human-powered vehicles and animal-powered vehicles. Overview Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive Volkswagen Beetle in combination with a motorcycle front end. Other trikes include that are specially constructed for off-road use. Three-wheelers can have either one wheel at the back and two at the front (2F1R), (for example: Morgan Motor Company) or one wheel at the front and two at the back (1F2R) (such as the Reliant Robin). Due to better safety when braking, an increasingly popular form is the front-steering "tadpole" or ... [...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 biking''). Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which often makes them heavier, more complex and less efficient on smooth surfaces. These typically include a bicycle fork, suspension fork, large knobby tires, more durable Bicycle wheel, wheels, more powerful brakes, straight, wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimized for topography, application (e.g., steep climbing or fast descending) and a frame with a bicycle suspension, suspension mechanism for the rear wheel. Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper seat 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 ...

Electric Bicycle
An electric bicycle, e-bike, electrically assisted pedal cycle, or electrically power assisted cycle is a 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 Bicycle pedal, pedaled by the rider and are therefore not electric motorcycles. E-bikes use Rechargeable battery, rechargeable batteries and typically are motor-powered up to . High-powered varieties can often travel up to or more than . 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 the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles, such as licensing and mand ...

Outline Of Cycling
Cycling, also known as bicycling or biking, is the activity of riding bicycles or other Human-powered transport, human-powered vehicles with Wheel, wheels, for transportation, recreation, exercise, sport, and other purposes. People who engage in cycling are called cyclists, bikers, or bicyclists. They may wear everyday clothing suited to their destination or specialized cycling attire, sometimes carrying an additional set of clothes. Cycling includes not only traditional two-wheeled bicycles but also unicycles, tricycles, quadricycles, and other human-powered transport, human-powered vehicles (HPVs). Some bicycles are equipped with Electric motor, electric motors (e-bikes) or other forms of Motorized bicycle, motor assistance. Cycling can be done individually or with others. Passengers may ride in front,for instance in the box of a cargo bike, sit on a luggage carrier, or use specially designed seats for children or pets. Some bicycles, such as tandem bicycles or multi-rider pa ... [...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 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. Some of Skelton's claims have been challenged. In December 2012, Eric Larsen made the first attempt to undertake an expedition solely by bicycle to the South Pole. After covering , a quarter of the distance to the South Pole, Larsen abandoned his attempt and cycled an additional back to Patriot Hills. On 27 De ...
