Weight
= Stability - The
treadmill weight is very important to the overall stability of the machine. The
heavier the treadmill the more solid the feel. Both the Smooth 5.15 and the Keys
Alliance 815 are good stable walking treadmills.
Larger
rollers provide for less friction and longer life - Large rollers provide
a smooth walking/running experience and extend the life of the treadbelt. There
is no substitute for size, the larger the better. That's why most commercial treadmills
are equipped with oversized rollers.
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. A
2.5 hp motor is more then adequate for the type of use these treadmills will provide.
Factory
Direct Sales - Smooth treadmills are sold factory direct and only on the Internet.
This eliminates the costly overhead from resellers. Keys sells their Alliance
815 treadmill only through retailers.
Shipping
Included - The prices for all of the Smooth Treadmills includes shipping to
your home.
