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 ...

Dahon is the world's largest manufacturer of folding bicycles [5] [need quotation to verify] with a two-thirds marketshare in 2006. [6] The company was founded in 1982 by David T. Hon, a former laser physicist, and is headquartered in Los Angeles, California, with assembly factories in China, Macau and Bulgaria. [7]
A 2001 NHTSA study found that 40% of passenger cars have at least one tire under-inflated by 0.4 bars (6 psi) or more. [1] The number one cause of tire failure was determined to be under-inflation. Drivers are encouraged to make sure their tires are adequately inflated at all times.
ISO 5775 is an international standard for labeling the size of bicycle tires and rims. The system used was originally developed by the European Tyre and Rim Technical Organisation (ETRTO). It is designed to make tire sizing consistent and clear.
Initially the company was the subject of litigation between Dahon and the founders, but a settlement was reached in 2013. The Arctic tern was the inspiration for the company name, due to the fact that it travels the longest distance of all migratory animals and is light and small, qualities the company attributes to its bicycles.
Ground pressure is the pressure exerted on the ground by the tires or tracks of a motorized vehicle, and is one measure of its potential mobility, [1] especially over soft ground. It also applies to the feet of a walking person or machine .
David T. Hon (born 1941) is a Guangdong-born [1] Taiwanese physicist, inventor and entrepreneur. He is best known as the inventor and founder of Dahon folding bicycles.Dahon has since grown to become the world's largest manufacturer and marketer of folding bikes [2] [3] with Hon still CEO to this day.
