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 Spirit
SL 198Treadmill and the Smooth 5.15have sufficient weight for a stable and solid
feel. Recommended for walking and lite running.
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, which results in longer life.
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. The Spirit has a respectable 2.3" rollers,
while the Smooth has 2.0" rollers, which are more than adequate.
Factory
Direct Sales - Smooth treadmills are sold factory direct and only on the Internet.
This eliminates the costly overhead from resellers. Spirit sells their SL 198
treadmill only through retailers.

Included - The prices for all of the Smooth Treadmills includes shipping to
