A stroller is provided having a stroller frame supported by at least one wheel and a handle. The handle includes a brake operator that is coupled to a brake assembly at the wheel. The brake operator is movable between a first position whereby the brake assembly is disengaged from the wheel, and a second position whereby the brake assembly engages the wheel to retard the wheel motion.

What is claimed is: 1. A stroller comprising: a stroller frame supported by rotatable wheels; a brake assembly supported by the frame and operably coupled to one of the rotatable wheels; a brake operator operably coupled to the brake assembly; and a handle connected to the stroller frame and having two handle sections each curved inward toward the other and terminating at a free terminal end spaced laterally across the stroller frame from the other, wherein movement of the brake operator to a brake position causes the brake assembly to retard rotation of the wheel, and wherein the brake operator is rotatably affixed to the free terminal end of one of the handle sections, wherein the brake operator further comprises a knob with an outer collar receiving an outer surface of the terminal end of the handle sufficiently loosely such that the outer collar and the outer surface can rotate relative to one another, an elongate groove on the outer surface, a channel extending in the terminal end of the handle, a neck oriented axially between axial ends of the knob, and an elongate channel extending into the neck and terminating at an aperture, the aperture anchoring the cable at a mouth of the channel, wherein the cable extends along the elongate channel, the groove, the channel in the terminal end, and to the brake assembly. 2. A stroller according to claim 1, wherein the brake operator is rotatable about an axis of the handle. 3. A stroller according to claim 1, wherein the rotatable wheels include two rear wheels and wherein the two rear wheels are locked from rotating when the brake operator is in the brake position. 4. A stroller according to claim 1, wherein the knob is rotatable and provides tactile feedback to a user when rotated between the brake position and a release position. 5. A stroller according to claim 4, wherein the rotatable knob includes a plurality of circumferentially spaced and axially extending grip surfaces. 6. A stroller according to claim 1, wherein the knob is a rotatable continuation of the handle. 7. A stroller according to claim 1, wherein the one wheel is rotatable about a wheel axle and the brake assembly retards rotation of the one wheel about the wheel axle. 8. A stroller according to claim 1, where the one wheel is rotatable relative to a generally vertical swivel axis and the brake assembly retards rotation of the one wheel about the swivel axis. 9. A stroller comprising: a stroller frame supported by wheels; a brake assembly operably coupled to one of the wheels; a stroller handle extending along an axis; and a brake operator operably coupled via a cable to the brake assembly and carried on the handle, wherein the brake operator is rotatable about a rotation axis coaxial with the axis of the handle, wherein rotation of the brake operator to a brake position causes the brake assembly to retard rotation of the one wheel, and wherein the cable is routed through an interior of a frame tube of the handle, wherein the brake operator further comprises a knob with an outer collar disposed at a free terminal end of the handle, the outer collar receiving a necked-down outer surface of the terminal end sufficiently loosely such that the outer collar and the outer surface can rotate relative to one another; an elongate groove on the necked-down outer surface; an elongate interior, centrally disposed cylindrical wall in the terminal end of the handle; a channel extending adjacent the cylindrical wall; a neck oriented axially between axial ends of the knob; and an elongate curved channel radially extending into a circumferential surface of the neck and terminating at an aperture, the aperture anchoring the cable at a mouth of the channel, wherein the cable extends along the elongate curved channel, the groove, the channel adjacent the cylindrical wall, and to the brake assembly. 10. A stroller according to claim 9, wherein rotation of the knob toward a release position spools the cable around the neck via the curved channel, thereby drawing a distal end of the cable from the brake assembly. 11. A stroller according to claim 9, wherein rotation of the knob toward the brake position unwinds the cable from the neck via the curved channel, thereby allowing the distal end of the cable to move toward the brake assembly. 12. A stroller according to claim 9, wherein the channel adjacent the cylindrical wall guides the cable along the axis of the handle frame during rotation of the knob. 13. A stroller according to claim 9, wherein rotation of the knob about the axis of the handle results in linear movement of the cable. 14. A stroller according to claim 9, wherein the brake operator includes an anti-rotation mechanism which maintains the brake operator in the brake position or in a release position when selected. 15. A stroller according to claim 9, wherein the one wheel is rotatable about a wheel axle and the brake assembly retards rotation of the one wheel about the wheel axle. 16. A stroller according to claim 9, where the one wheel is rotatable relative to a generally vertical swivel axis and the brake assembly retards rotation of the one wheel about the swivel axis. 17. A stroller comprising: a stroller frame supported by wheels; a brake assembly operably coupled to one of the wheels; a stroller handle; and a brake operator operably coupled via a cable to the brake assembly and carried on the handle, wherein the brake operator is rotatable about an axis of the handle, wherein rotation of the brake operator to a brake position causes the brake assembly to retard rotation of the one wheel, and wherein the cable is routed through an interior of a frame tube of the handle, wherein the brake operator further comprises a knob with an outer collar disposed at a free terminal end of the handle, the outer collar receiving an outer surface of the terminal end sufficiently loosely such that the outer collar and the outer surface can rotate relative to one another; an elongate groove on the outer surface; a channel extending in the terminal end of the handle; a neck oriented axially between axial ends of the knob; and an elongate channel extending into the neck and terminating at an aperture, the aperture anchoring the cable at a mouth of the channel, wherein the cable extends along the elongate channel, the groove, the channel in the terminal end, and to the brake assembly.
