SPIRIT CG 800 Elliptical, CG800

On an elliptical,multiple cranks are structured between the pedal and the flywheel. The crank attached on an elliptical's flywheel is closer to the flywheel's perimeter. However, both the e-glide's flywheel and cranks mount on the same drive axle. As the result, the e-glide's flywheel is directly driven by the pedals. This transmission system therefore is named the Direct Drive.Inertia comes from the flywheel's continuous motion, rendering smoothness and some force to help users propel. Since the e-glide's flywheel and the cranks share the same axle, its inertia is especially effective in both forward and reverse pedaling motion.
