All terrain bikes, also known as ATBs, are designed for cycling on a variety of terrains, including rough trails, soft sand, and rocky terrain. They are also commonly referred to as mountain bikes, off-road bikes, and trail bikes. Adventure bikes, gravel bikes, and fat bikes are also popular synonymous terms for these versatile bicycles. Adventure bikes are designed for long-distance touring on rugged terrain, while gravel bikes are made for riding on unpaved roads and rough paths. Fat bikes have oversized tires that allow them to ride on soft surfaces such as snow and sand. Regardless of the term used, all terrain bikes are an exciting way to explore the great outdoors.
