What is a FAT Bike?

Fatbikes are designed to carry adventurous riders out into wild places not normally accessible to bicycles. Extra wide 4-5 inch tires on 80mm-100mm wide rims run at a low inflation give a large foot print and massive grip which helps the Fat bike float through sand, snow, mud and other variable terrain, opening the door to epic beach rides, untracked exploration and mid-winter expeditions.

Fat tires also provide maintenance simplicity to a bike, eliminating complicated rear suspension by giving a degree of free suspension. Drive and braking are improved, especially on less than ideal surfaces. However it’s the sideways grip that really impresses, at speed cornering grip is excessive. If the tyres don’t stick, it’s likely nothing will. Most importantly Fat Bikes are Fun!
