An in-line roller skate has a forward control wheel 32 positioned above the surface on which the skate is supported by intermediate wheels 34 and 36. The forward control wheel 32 occasionally contacts the surface during normal skating motion and rotates freely when the skater exerts forward motion through the wheel to the surface. When the skater tilts the skate forward to place the forward control wheel into contact with the surface and exerts rearward forces through the forward wheel to the surface, the bearing assembly 33 of the forward wheel locks the wheel against counterclockwise rotation and enables the skater to apply additional thrusting forces to the surface. A rearward control wheel 38 operates in reverse fashion to provide the skater with braking forces.

[ I claim:] [1.] An in-line roller skate having a boot (10) suitable for fitting on a foot of a user, a support member (12) extending longitudinally along the bottom of the boot, and at least one intermediate wheel (34) rotatably mounted on the support member and capable of supporting the boot and its user, comprising:at least one control wheel (32) rotatably mounted on the support member outwardly of the intermediate wheel, said control wheel being located so that the lowest point of its circumference is closer to the boot than the lowest point of the circumference of the intermediate wheel, androtation inhibiting means (33) associated with said control wheel (32) for inhibiting rotation of the control wheel when the control wheel is applying force in one direction to the surface below the boot but enabling rotation more readily when the control wheel is applying force to the surface in the opposite direction, said rotation inhibiting means comprising a bearing assembly (33) that locks the control wheel when the control wheel is applying force to the surface below the boot in a rearward direction.
