Abstract

An elliptical exercise machine having a frame adjustable between an operational position and a folded position. A removable outer shell is hingedly connected to a base upon which the elliptical machine stands. The outer shell is configured to resemble two halves of a coffee table that are pivoted to either cover or expose the machine. Each handlebar on the machine includes a hinged section that is movable between a folded and an operational position. The machine is further provided with a latching assembly to lock the flywheel against rotation and to correctly position the same so that the outer shell can be placed over the folded machine.
