Abstract: An elliptical propulsion system for stroller assemblies. The elliptical propulsion system has a propulsion frame assembly, a propulsion assembly, and a propulsion wheel assembly. The propulsion frame assembly is removably mounted onto a stroller assembly. Further having elliptical motion means to cause propulsion wheel assembly to rotate and propel the stroller assembly when the propulsion frame assembly, propulsion assembly, and propulsion wheel assembly are in an extended configuration.

Abstract: An elliptical stroller assembly including a stroller frame assembly with a stroller assembly mounted thereto, first and second wheel assemblies, a propulsion frame assembly and propulsion assembly. The propulsion frame assembly and the propulsion assembly may be in an extended or in a retracted configuration with respect to the stroller frame assembly and the stroller assembly. In the extended configuration, the propulsion assembly propels the stroller frame assembly and the propulsion frame assembly is removably secured to a first fixed mount. In the retracted configuration, the propulsion assembly does not propel the stroller frame assembly. At this position, the propulsion frame assembly is removably secured to a second fixed mount.
