Trials is to a large extent a cousin to normal mountain biking. It is extremely skillful and requires an excellent sense of balance. The bikes are super light and have no gearing and no saddle. Small frame sizes are used to give maximum clearance from the rider. These riders can literally cycle along on railings on one wheel. The bike is cantelevered to enable large drop off's and hops to be done using very little forward motion.
