A foldable baby stroller having left and right side front wheel supports with a front wheel mounted to a forward end, and a laterally extending rear axle with a rear wheel mounted at each end. Further included are left and right side rear wheel supports, each with a lower end attached to the axle; and left and right side handle supports with a handle spanning between them. Also included are left and right side folding assemblies, each having a pair of mounting plates and a guide pivotally attached therebetween. A rearward end of one of the front wheel supports is fixedly attached between each plate pair. A forward end of one of the handle supports is pivotally attached between the plates and rotatable relative to the front wheel support. An upper end portion of one of the rear wheel supports is positioned between the plates and pivotally attached to the forward end of the handle support for application of a drive force thereto. The guide has an aperture with one of the rear wheel supports slidably disposed therein. The guide and guide aperture are configured to rotate the rear wheel support and to slide the rear wheel support in the guide aperture in response to rotation of the handle support. In several embodiments, each of the left and right side folding assemblies uses a pair of meshing gear segments, one being attached to the handle support and one being attached to the rear wheel support.
