Abstract: A braking system preferably for an in-line skate includes a brake pad mounted to a forward end of a skate frame and an elevated front wheel attached to the skate frame by two pivot arms. The pivot arms are biased forward which is in a clockwise direction with respect to their pivot point. When skating normally, the pivot arms bias the wheel against the brake pad, but the wheel is elevated from the skating surface and thus the brake is not engaged. When skating in a rearward direction, or desiring a push start, the skater rotates the toe portion of the skate downward and raises the heel. The front wheel will engage the skating surface and the reaction force on the wheel due to friction between it and the skating surface which will urge the wheel forward and increase the contact pressure between it and the brake pad.

Abstract: Mono-wheel roller skates having a single large main wheel which supports the skater and a pivotally mounted smaller brake actuation wheel which contacts the ground when the skates are tipped backward and which is operatively connected to caliper brakes which grip the main wheel to slow or stop the skater.

A removable rock guard works in conjunction with a built-in rail guard to deflect debris and prevent it from accumulating in front of the main wheel. An arcuate toe push-off piece or a unidirectionally rolling toe push-off wheel allows pushing off from the toe of the skate such that a skater can use an in-line skating stroke wherein the skates remain pointed in the direction of travel rather than angled outward thereto as is usually required for skating.
