The stroller of claim 1, wherein the first gear has a first pitch and the second gear has a second pitch different than the first pitch, and wherein the third gear includes a first gear portion with the first pitch and a second gear portion with the second pitch, the first and second portions of the third gear rotating as a unit, and the first gear portion of the third gear is positioned in the first aperture in driving engagement with the first gear and the second gear portion of the third gear is positioned in the second aperture in driving engagement with the second gear. 7. A stroller, comprising: left and right side laterally spaced-apart handle supports, each of the handle supports having a first end portion, a second end portion, and are connected at their first ends;left and right side laterally spaced-apart front wheel supports, each of the front wheel supports having a first end portion, a second end portion, and are at through their first ends;left and right side laterally spaced-apart rear wheel supports, each of the third members having a first end portion, a second end portion, and are connected at their first ends; andleft and right side laterally spaced-apart folding assemblies, each of the left and right side folding assemblies having a first rotatable plate and a second rotatable plate rotatably mounted on a pivot member to pivot about a common axis in parallel planes, wherein the front wheel supports are driven to rotate relative to the rear wheel supports by movement of the handle supports. 8. The stroller of claim 7, wherein the first rotatable plate has a first aperture with a first gear and the second rotatable plate has a second aperture with a second gear, each of the left and right side folding assemblies further having a third gear positioned in both the first and second apertures such that the first gear is formed at a first edge portion of the first rotatable plate defining a portion of the first aperture and the second gear is formed at a second edge portion of the second rotatable plate defining a portion of the second aperture of each the left and right side folding assemblies, with the first edge being radially outward of the axis of the third gear and the second edge being radially inward of the axis of the third gear, such that the third gear is in driving engagement with the first gear and the second gear so that the first rotatable plate and the second rotatable plate rotate relative to each other in geared coordination. 9. The stroller of claim 8, wherein one of the second end portions of a first one of the first, second and third members being attached to the first rotatable plate, one of the second end portions of a different second one of the first, second and third members being attached to the second rotatable plate, and one of the second end portions of another different third one of the first, second and third members supporting the pivot member. 10. The stroller of claim 7, wherein the first and second rotatable plates each have a central portion with the central portions arranged in face-to-face juxtaposition. 11. The stroller of claim 7, wherein the first and second rotatable plates each have a planar arm portion projecting therefrom and in coplanar relation therewith, the one of the second end portions attached to the first rotatable plate being attached to the arm portion thereof and the one of the second end portions attached to the second rotatable plate being attached to the arm thereof. 12. The stroller of claim 8, wherein the first gear has a first pitch diameter and the second gear has a second pitch diameter, with the first pitch diameter and the second pitch diameter not being the same. 13. The stroller of claim 12, wherein the first pitch diameter of the first gear is sized to rotate the one of the first, second and third members attached to the first rotatable plate through a first angle of rotation from a folded position to an unfolded position, and wherein the second pitch diameter for the second gear is sized to rotate the one of the first, second and third members attached to the second rotatable plate through a second angle of rotation from a folded position to an unfolded position, with the first and second angles of rotation not being the same. 14. The stroller of claim 8, wherein the first and second rotatable plates are rotatably mounted to rotate about the common axis through spaced apart parallel rotation planes with the common axis transverse to the first and second rotatable plates, and the third gear is rotatably mounted to rotate about an axis transverse to the rotation planes of the first and second rotatable plates and spaced apart from the common axis of the first and second rotatable plates. 15.
