Smooth 9.45ST Treadmill Review

Smooth 9.45ST Treadmill

Smooth 9.45ST Treadmill

The Smooth 9.45ST treadmill is similar to the Smooth 9.35HR but with bigger running surface and better warranty for about $400 more.

Plus, all the features that made the 9.35HR one of the best you can buy below $2,000 a few years ago are also available in this model which makes this one of the best buy treadmills below $2,500.

Is It for You?

If you need a quality treadmill with a powerful motor and large running space, then this machine is perfect for you. It provides one of the best values you will find in a $2,300 machine. This treadmill is especially useful to hardcore runners since the cushioning can be adjusted to accommodate all methods of running.

Update: This treadmill has been discontinued.

What You’ll Be Getting

Just like the 9.35HR, the Smooth 9.45ST treadmill also comes with the Hydra Suspension System which is exclusive to Smooth treadmills. This feature allows you to custom adjust the shock absorption of your machine to fit your style of running.

The 3.0HP continuous duty motor has a maximum speed of 11.2mph which is more than enough for most runners. It also features 15 incline levels for those who need more intensity in their workouts.

The 60” x 20” running surface offers an extra long running deck. This is perfect for tall people who have longer strides. While commercial grade belt was triple-laminated with phenolic resin to provide low friction so the belt won’t get damage easily and would last a lifetime.

The display features a large 6” LED which reads out basic information about your workout and a hand pulse grip that checks your heart rate. All these data are given to you so can easily monitor your progress.

This machine comes with 6 pre-set programs to help keep your workouts fresh. And up to 9 people can use this machine and save their profiles in it so you won’t need to key in your personal settings before every workout. There is also a heart rate control program that comes with a wireless transmitter and receiver that adjusts the intensity of your workout depending on how you set your target heart rate.

Another excellent addition to the Smooth lineup is the patented motion control system. This used to be a feature only found on Evo treadmills but are now also available to Smooth Fitness. What this unique feature does is it allows you to adjust the speed of your run by waving your hand over light sensors on the handrail. This is perfect for hardcore runners who usually run on a fast pace as it won’t require you to uncomfortably lean and reach forward while in motion, just to change your speed.

And finally, the Smooth 9.45ST treadmill boasts of a lifetime warranty on everything (motor, parts and electronics) and a 2 year in-home service warranty. These long warranties are definitely hard to beat and only prove that this machine comes with excellent quality.


Other than the delivery delays that Smooth has been known for in the past, it would be hard to find a weakness in this machine. This is one of the best treadmills you can buy below $2,500.


If you’re in the market for a huge treadmill with excellent features and quality, then I highly recommend the Smooth 9.45ST treadmill. But if you can’t afford a $2,300 treadmill then I suggest you settle for the cheaper Smooth 9.35HR or visit our best buy treadmills page for more choices.
