Abstract
A linkage mechanism with handles linked to an elliptical motion trajectory includes a main body having two guiding tracks with a changeable lifting angle, a flywheel assembly and two handles installed on a front side of the main body, a first linkage rod pivotally attached between the two handles and two cranks of the flywheel assembly. The two pedals respectively include a front end, and a second linkage rod is pivotally attached between the front end and each one of the cranks. A third linkage rod is pivotally attached between each one of the pedals and each one of the handles. Each one of the pedals along each one of the guiding tracks, and drives each one of the handles and the flywheel assembly to move.
