A foldable stroller has a frame assembly reconfigurable between an in-use configuration and a folded configuration. The frame assembly has a left and a right frame side and each frame side includes an elongate bottom part having a front end and a back end. Each bottom part is oriented extending generally from a front to a back of the frame assembly. A fold latch is on the frame assembly and has two latch parts pivotally coupled to one another. A push arm has a lower end connected to one of the latch parts and extends upward and rearward to a handle. A front leg has a lower end pivotally coupled to a front end of the bottom part and extends upward and rearward to an upper end connected to the other of the latch parts. A support strut has an upper end pivotally coupled to the fold latch at a pivot axis and has a lower end pivotally coupled to the bottom part forward of the back end at a pivot connection. The pivot connection of the support strut in one example is positioned further forward than the pivot axis. The support strut in one example is positioned outboard relative to the bottom part.

A foldable stroller according to claim 1, further comprising: a release mechanism carried on the frame assembly and movable to release the fold latch such that the push arm and the one latch part can be pivoted relative to the front leg and the other latch part from the in-use configuration to the folded configuration. 5. A foldable stroller according to claim 1, wherein the two latch parts are pivotally coupled to one another at a latch pivot that is spaced from the pivot axis of the support strut. 6. A foldable stroller having a frame assembly reconfigurable between an in-use configuration and a folded configuration and having a left and a right frame side, each frame side comprising: an elongate bottom part having a front end and a back end and being oriented extending generally from a front to a back of the frame assembly; a fold latch having two latch parts pivotally coupled to one another; a push arm having a lower end connected to one of the latch parts, the push arm extending upward and rearward to a handle; a front leg having a lower end pivotally coupled to a front end of the bottom part and extending upward and rearward to an upper end that is connected to the other of the latch parts; and a support strut having an upper end pivotally coupled to the fold latch at a pivot axis, and having a lower end pivotally coupled to the bottom part forward of the back end at a pivot connection, wherein the support strut is positioned outboard relative to the bottom part and the pivot connection is aligned with the bottom part. 7. A foldable stroller according to claim 6, wherein the pivot connection of the support strut is positioned further forward than the pivot axis. 8. A foldable stroller according to claim 6, wherein the upper end of the support strut is pivotally coupled to the one latch part at the pivot axis. 9. A foldable stroller according to claim 6, further comprising: a release mechanism carried on the frame assembly and movable to release the fold latch such that the push arm and the one latch part can be pivoted relative to the front leg and the other latch part from the in-use configuration to the folded configuration. 10. A foldable stroller according to claim 6, wherein the two latch parts are pivotally coupled to one another at a latch pivot that is spaced from the pivot axis of the support strut. 11. A foldable stroller comprising: a frame assembly movable from an in-use configuration to a folded configuration, the frame assembly having a front, a back, and left and right sides in the in-use configuration; and a seat positioned between the left and fight sides, wherein each side of the frame assembly includes, an elongate bottom part having a front end and a back end and being oriented extending generally from the front to the back of the frame assembly; a front leg having a lower end pivotally connected near the front end of the bottom part and extending in the in-use configuration upward from the bottom part and rearward toward the back of the frame assembly and terminating at an upper end; a push arm pivotally coupled at a pivot joint to the upper end of the front leg and extending upward and rearward therefrom; and a support strut having a lower end pivotally connected to the bottom part at a pivot connection located between the front end and back end on the bottom part, the support strut terminating at an upper end at a pivot axis located in proximity to the pivot joint of the front leg and the push arm, wherein the pivot connection of each support strut is positioned further forward than the pivot axis, and wherein the strut is positioned outboard relative to the respective bottom part, front leg, and push arm. 12. A foldable stroller according to claim 11, wherein the pivot connection of each support strut is aligned with the bottom part. 13. A collapsible stroller according to claim 11, further comprising: a handle extending between upper ends of the push arms on the left and right sides; a latch release carried on the handle; and a fold latch on each of the left and right sides, each fold latch configured to lock the frame assembly in the in-use configuration and being actuable by the latch release to permit the frame assembly to be moved to the folded configuration. 14. A foldable stroller comprising: a frame assembly having a front, a back, and left and right sides when in an in-use configuration, the frame assembly reconfigurable to a folded configuration; and a seat positioned between the left and right sides and supported by the frame assembly, the frame assembly having two elongate bottom parts, one on each of the left and right sides, each bottom part having a front end and a back end, two front legs, one on each of the left and right sides, each front leg having a lower end pivotally connected near the front end of a respective one of the bottom parts, each front leg extending upward from the bottom part and rearward toward the back of the frame assembly in the in-use configuration and terminating at an upper end, two fold latches, one on each of the left and right sides, each fold latch having a first part connected to the upper end of a respective one of the front legs and a second part pivotally connected to the first part, two push arms, one on each of the left and right sides, each push arm connected to the second part of a respective one of the fold latches and extending upward and rearward from the upper end of the front leg in the in-use configuration, and two support struts, one on each of the left and right sides, each support strut having a lower end pivotally connected to a respective one of the bottom parts at a connection point and terminating at an upper end pivotally connected to a respective one of the fold latches at a pivot point, wherein the connection point of each strut is positioned further forward than the pivot point, and wherein the bottom part is positioned laterally inward relative to the respective support strut on each of the left and right sides. 15.
