Offroad bicycles are also known as mountain bikes, dirt bikes, or trail bikes. These bikes have sturdy frames, tires with knobby treads, and suspension systems that allow them to withstand the rugged terrain of mountain trails and dirt roads. Similarly, All-terrain bicycles or ATBs are designed for use on both pavement and off-road terrain. They often have a hybrid frame that combines features of a road bike and a mountain bike, such as a lightweight frame for speed and a suspension fork for shock absorption. Adventure bikes, gravel bikes, or cyclocross bikes are a newer breed of off-road bicycles that have become popular for their versatility on both paved and unpaved terrain.
