GLOBAL FATBIKE DAY. On December 5th, 2016, people from all over the globe, will get out for a ride on their FatBikes.  Use the hashtag #GFBD2016.

A FatBike, also called wide tire bike, is a bicycle with over-sized tires, typically larger than 3.8 in (97 mm) and rims 26 inch (66 mm), designed for low ground pressure to allow riding on soft unstable terrain, such as snow and sand. 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 5 psi (340 hPa) to allow for a smooth ride over rough obstacles. A rating of 8–10 psi (550–690 hPa) is suitable for the majority of riders.

In 2013 and 2014 there were three cycling expeditions to the South Pole. Maria Leijerstam became the first to cycle to the South Pole, across the South Pole Traverse road. She rode a tricycle with FatBike tires. Juan Menéndez Granados skied and rode a FatBike to the South Pole. On 21 January 2014, Daniel P. Burton became the first person to ride a bike across Antarctica to the South Pole. Burton started at Hercules Inlet, and biked 775 mi (1,247 km) to the South Pole. Also known as Fatty 

Fat Bikes were invented for winter trail riding and racing in sub-arctic Alaska on the Iditarod Trail and for touring the deserts of New Mexico. They are extremely versatile bikes, capable of traversing diverse terrain types including snow, sand, desert, bogs, mud, pavement, or traditional mountain biking trails.
