At the most basic level, Trials Riding can be summed up as bicycle handling skills. It evolved from motorbike trialss riding (riding up, over stunts, man-made or natural) into an off-season bicycle pastime. It now has a strong, though small following and can be seen worldwide. Skills taken from Trials riding can be used practically on any bicycle for balance, standing still while still on the pedals, braking, and many other uses. Trials-specific bicycles are usually modified mountain bikes (good brakes, light with little extra baggage) or modified BMX bikes.
