NordicTrack E 6.3 Elliptical Review
treadmill Doctor Note :
The single wheel and track design of the E 6.3 is a serious drawback over the long term.
Single wheel and track systems are inherently less stable while in use in our opinion. That's why Sole has been so successful. In addition of their use of large flywheels, Sole typically uses a dual wheel and ramp design.
