Mountain Bike Trials is a variant of Bicycle Trials. Bicycle Trials evolved from Motorcycle Trials. In Bicycle Trials the competitor has to complete a course, laden with obstacles. Mistakes, such as touching the ground and falling off are penalized on a points basis, hence the competitor with the least points is the winner. Mountain Bike Trials follows the same principle but on Mountain Bikes. A new type of MTB Trials (Mountain Bike Trials) has recently evolved, called Speed Trials, in this the winner completes the course in the shortest time, mistakes are punished on a time penalty system.
