A wheel of a unicycle has two beams disposed in parallel in a rim. A bolt is extended between the beams. The head of the bolt is disposed away from the geometric center of the wheel and the bolt extends through the geometric center of the wheel. Two plates which are connected together by a nut are slidably disposed between the beams. The bolt is engaged with the nut. An axle is extended outward from each plate. A rotation of the head of the bolt causes the axles to move either away or toward the geometric center of the wheel.
