1. A collapsible wagon-style stroller comprising:
a stroller frame comprising a handle and a group of one or more tubes, the group of one or more tubes comprising:
a forward upper tube,
a rear upper tube,
a forward leg tube,
a rear leg tube, and
at least one hub having a slidable release grip, wherein the forward upper tube, rear upper tube, forward leg tube, and rear leg tube are coupled to one another via the hub;
wherein when the stroller is in an operable configuration and when the slidable release grip is actuated, the forward upper tube rotates from its respective initial position about the hub towards the forward leg tube, the forward leg tube rotates from its respective initial position about the hub towards the rear leg tube, the rear upper tube rotates from its respective initial position about the hub towards the rear leg tube, and the rear leg tube rotates from its respective initial position about the hub towards the forward leg tube, and
wherein when the forward upper tube, rear upper tube, forward leg tube, and rear leg tube have been rotated from respective initial positions to respective folded positions, the stroller is in a folded configuration, and
wherein the handle comprises:
a first handle tube and a second handle tube, wherein the first handle tube is slidably coupled within the second handle tube,
an inner support lock coupled to an outer support lock and configured to slide between a locked position and an unlocked position,
a first bottom handle support coupled to the rear leg tube and configured to secure the outer support lock when the handle is positioned in the first operable position and the outer support lock is in the locked position,
a handle safety stop positioned on the hub and configured to secure the inner support lock when the handle is positioned in the first operable position and the inner support lock is in the locked position, and
a handle storage detent positioned on the hub and configured to secure the inner support lock when the handle is in the second operable position and the inner support lock is in the locked position,

wherein the first handle tube is configured to slide within the second handle tube to contact the inner support lock and the outer support lock, disengaging the inner support lock and the outer support lock from the locked position to the unlocked position,
wherein the handle safety stop is configured to resist rotation of the handle into the first operable position unless the inner support lock and the outer support lock are in the unlocked position, thereby preventing injuries to occupants of the stroller, and
wherein the handle is configured to rotate between the first operable position, the second operable position, and the collapsed position when the inner support lock and the outer support lock are in the unlocked position.
