You get almost everything you need from a treadmill with this one. It’s packed with features. Here is a complete breakdown of its specifications.

Belt Dimensions: 60″ x 20″

Motor: 3.5HP

Speed: Up to 12.0 MPH

Incline Adjustment: Yes (0 – 15%)

Presets: Yes (26 preset workout programs)

Display: Yes (5.5” display)

With 3.5HP might be lower compared to some of the other models out there. However, for home equipment, this should be plenty of power.

Build Quality

Nautilus Treadmill Series T618 avoids the common pitfalls of home equipment – being cheaply built. The build quality of this treadmill is gym-grade with great materials and solid construction.

The motor can produce consistent power and the motor rollers are large too. You get 2.75″ rollers for the belt. This puts less strain on the motors, which means you end up with longer-lasting motors. They are durable and should last you a long time.

Design-wise, it’s not too fancy. The treadmill is professional looking with muted color tones – mostly black with some blue accents that give it some character. As with most treadmills, you get two handlebars. They give you more stability during workouts. It can also be folded up and put away when not in use.

Adequate Performance

Alright, let’s get into the stuff that matters. When you are looking for a treadmill for your home, there are a couple of things you need to keep an eye out for. First up are the motor and the power. Then you have the build quality and some added extra features you get.

The 3.5HP, as mentioned, is quite adequate for home use. You can most definitely find more powerful treadmills out there – but for home workouts, 3.5HP is more than enough.

If you are on the heavier side, a more powerful motor could be more useful for you. Apart from that, this treadmill features incline options as well. It gives you up to 15% incline for high-intensity workouts.

Speaking of high-intensity workouts, the Nautilus Treadmill Series T618 can go up to 12 MPH. That is pretty fast for home treadmills if you ask us. The belt is also very spacious. You get a 60” X 20” belt. It should feel very comfortable when running.

There are also a ridiculous number of preset workouts. You get a total of 26 preset workouts – with emphasis on different exercise types. You have cardiovascular workouts, interval training, and even weight loss training.

Cardio workouts done the correct way can help quite a lot if you are trying to lose weight. With the mix of different preset workouts and the monitoring options, you can get a pretty decent calorie burning going on with this treadmill.

Speaking of monitoring options, let’s take a look at the extra features and all the creature comforts you get with this.

First up, you get a large LCD screen with different workout monitoring options. We are big advocates of tracking your workouts over here. Tracking helps you stay on top of your workouts. The data gives you valuable insight into how your workouts are going and what you can do to make it better.

Your knees are also going to be thankful. This one has rebound cushioning which minimizes the impact on your knees.

You can even pair the treadmill with the Nautilus Trainer Apps and other fitness tracking apps. You also get very detailed heart monitoring options. When you need some extra entertainment during your workouts, just use the built-in tablet holder.

Get a show going or jam out to some tunes while running. In need of a refreshment? This has you covered as well. There is a water bottle tray too.


The Nautilus Treadmill Series is a line of very well built and high-performance treadmills that should fit perfectly into any home gym set-up. With tons of smart features and durable built quality, this is a serious value for health enthusiasts.
