Discipline rather exotic, it is a demonstration of agility and balance of the pilot.
The trial consists in carrying out rises of obstacles, such as: cars, pallets, rocks...
Balance is the principal stake of this discipline. The bicycles are specifically manufactured to adapt to the pilot seeking balance with the stop: but also during its extensions on aft wheel.
This discipline is spectacular, impressive and sometimes époustouflante from the agility of the pilots.
The principal marks which dominates, on this market are, KOXX and VARIO.
