Fatbike being ridden over snow. 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 3.8 in (97 mm) or larger and rims 2.16 in (55 mm) or wider, designed for low ground pressure to allow riding on soft, unstable terrain, such as snow, sand, bogs and mud. [1]
For example, if a fat-bike tire is inflated to 0.5 bar (50 kPa; 7.3 psi) gauge pressure at room temperature 20 °C (68 °F) and then the temperature is decreased to −10 °C (14 °F) (a 9% decrease in absolute temperature), the absolute pressure of 1.5 bar (150 kPa; 22 psi) will be decreased by 9% to 1.35 bar (135 kPa; 19.6 psi), which ...

In the 1982 Great American Bike Race, later renamed the Race Across America, he completely changed the parameters, cycling for 9 days and 20 hours with three other cycling pioneers John Howard, John Marino and Michael Shermer. [1] [2] [3] Lon Haldeman became the first person to ride a bicycle across the United States in less than 10 days.

For example, a 10% change in load or inflation pressure usually does not result in a 10% change in the contact patch area [3] because the load or pressure on a tire can be altered freely, and the contact patch area is affected by the tire geometry and stiffness. Further, the size of the contact patch cannot be simply calculated as load divided ...
The inner width of the rim on which the tire is mounted should be about 65% of the tire's nominal section width for tires smaller than 30 mm and 55% for those larger. The section height of a tire is usually identical to its section width (for tires less than 28 mm, 2.5 mm have to be added to the width to get the height).
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
