Abstract: A stroller assembly can include a stroller frame with a front leg and first and second rear legs. The front leg having at least one front wheel connected thereto. The first and second rear legs have rear wheels connected thereto. The rear wheels are rotatable about a horizontal rotation axis of the rear wheels. The rear wheels are spaced from the at least one front wheel in a rearward direction, with the rearward direction being perpendicular to the horizontal rotation axis. A handle assembly is connected to the front leg and the rear legs. The handle assembly includes a handlebar positioned between the first and second rear wheels. The handlebar is aligned with a vertical axis extending through and perpendicular to the horizontal rotation axis, or offset from the vertical axis such that the handlebar is positioned closer to a center of the stroller frame than the horizontal rotation axis.
