Abstract
An exercise wheel comprises a housing, a hold bar, a main wheel, an elastic device, an auxiliary wheel set, and a front wheel. The hold bar is put through the housing such that both ends of the hold bar are jutted out of the housing to serve as hand grips. The main wheel is provided with a protrusion and is rotatably mounted on the hold bar. The elastic device is disposed between the main wheel and the housing for providing the main wheel with a recovery spring force. The main wheel is connected with the auxiliary wheel set which is pivoted in the housing such that the auxiliary wheel set in motion is stopped by the protrusion of the main wheel at such time when the auxiliary wheel set is located at a predetermined position. The front wheel comes in contact with a surface on which the exercise wheel rolls.
