Fourcross is a form of four-wheeled downhill mountain biking, which has the benefit of being suitable for disabled riders. It is a gravity sport, there's no propulsion. The rider has to actively use their body to corner bends and to prepare for jumps, through leaning their upper body and pumping their chair.[1] The rider sits nearer to the ground than on a regular mountain bike. This makes the ride seem much faster, and that gives an adrenaline rush. These bikes can be handled by the riders themselves, without any assistance, and that gives independence and a feeling of freedom. In 2007, there were about 20 fourcrossers around the world.[2]
