Abstract: A rider propelled roundabout apparatus includes a stand and a roundabout assembly supported on the stand for rotation about a substantially vertical axis. The assembly is provided with at least one seat for supporting a rider, and a drive bar is supported on the stand for rotation relative to the stand. A roller clutch situated between the stand and the drive bar prevents rotation of the drive bar in a first rotary direction while permitting rotation of the drive bar in a second rotary direction. The rider propels the assembly in the second rotary direction by exerting a force on the drive bar in the first rotary direction. The drive bar is free to rotate with the rider in the second rotary direction so that the rider may continuously hold onto the drive bar and exert additional force on the drive bar in the first rotary direction at any time to further propel the assembly.
