A fatbike, also called wide tire bike, is a bicycle with over-sized tires, typically 3.8 in (97 mm) or larger and rims 2.6 in (66 mm) or wider, 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.
Fatbikes were invented for winter trail riding and racing in sub-arctic Alaska on the Iditarod Trail and simultaneously, 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. In several states, fatbike-dedicated groomed winter trails have been created.
