Weight = Stability - The treadmill weight is very important to the overall stability of the machine. The heavier the treadmill the more solid the feel. In this price range both the Keys 4200 Treadmill and the Smooth 7.1 have sufficient weight for a stable and solid feel.

Motor Output - Continuous duty horsepower ratings are the amount of power a motor will produce "continuously" at a given RPM (revolutions per minute). Continuous duty HP is the "working power" of a treadmill motor, providing constant power to the drive belt. The higher the HP output, the less stress on the motor resulting in longer life.

Factory Direct Sales - Smooth treadmills are sold factory direct and only on the Internet. This eliminates the costly overhead from resellers. Keys sells their 4200 treadmill only through retailers.

Shipping Included - The prices for all of the Smooth Treadmills includes shipping to your home.
