With respect to the right fixed handle structure, it includes two vertical members 300 coupled with the rear portion of the frame.
  • forward force on the handle imparts an upward force on the freadle, by way of the wheel. If the wheel is captured in a channel or other structure on the bottom of the treadle, then downward movement of the freadle causes the wheel to roll backward and upward movement causes the wheel to roll forward, which imparts rearward and forward movement, respectively, on the vertical handle section. Further, if the wheel is captured in a channel or other structure on the bottom of the treadle, forward force on the handle imparts an upward force on the freadle, by way of the wheel 318, and rearward force on the handle 310 imparts a downward force on the freadle (12A, 12B), also by way of the wheel.
  • Figures 38-45 illustrate various embodiments of an exercise device employing one or more flywheels to impart rotational momentum to the tread belts. These embodiments may be used with a motor or without a motor. As such, the flywheel may add or enhance movement of the fread belts.
