Obstacles are traversed using various moves. Hopping is achieved by suddenly forcing the unicycle pedals downwards while holding the seat, the reactive forces resulting from the compression of the tire lift the unicycle into the air. Jumping is a similar to hopping, except that the unicycle seat is held in front of the rider to allow greater height to be achieved. Pedal grabs and crank grabs involve a hop or jump to land the unicycles pedal or crank on the edge of an object, and then a second hop or jump to land the unicycle fully on the object.
Although unicycle trials can be performed on a standard unicycle, many are not designed for the forces which are caused by unicycle trials. A trials unicycle is built with unicycle trials in mind, and is therefore designed to better cope with these stresses.
