Good / The Nautilus T614 Treadmill has a better screen than cheaper competitors that we’ve reviewed, and the speed, incline rate, and motor have proper specifications.
Bad / The Nautilus T614 Treadmill has tons of customer complaints and the warranty policy as well as problems we’ve noted in other users make this treadmill seem very faulty and unreliable.
Verdict / While the Nautilus T614 Treadmill could be a decent treadmill if it works well, the short 90-day labor policy, as well as the risk of spending money to return the product, make it a questionable purchase.
Spend a little more money for something like the ProForm Pro 2000, or purchase a treadmill like the Sole F80 to be set for years to come.

Nautilus T614 Treadmill Review


The Nautilus T614 Treadmill has a mid-range price of $749. It’s more expensive than a lot of treadmills we’ve reviewed on Amazon but still not as high as a price point that we’ve gauged to guarantee at least a semi-competent treadmill.

Unfortunately, in the case of budget treadmills, you get what you pay for. Here at least, the price is a bit more expensive than the $300-500 treadmills we’ve reviewed–so what more do you get for the increase in price?

In this Nautilus T614 Treadmill review, we will help you decide if you should spend $749 or save up more money to buy a better model like the Sole F80.


Nautilus T614 Treadmill Review

The Nautilus T614 Treadmill has a decent feature set. For $749 you get a decent high-resolution blue backlit LCD monitor and a charging USB port that lets you data export to or

As far as speeds and workouts, the Nautilus T614 Treadmill has  0 to 12 MPH, 0 to 12% incline, 2.75 CHP motor, and a 20-Inch x 55-Inch dimension. There are 22 programs and up to 2 user profiles.

Surprisingly, the Nautilus T614 Treadmill includes acoustically chambered speakers and a 3-speed fan to keep you cool. The treadmill also comes with grip and telemetry-enabled heart rate which is fairly standard. It’s foldable, with a 300 lbs and it comes with rollers if you have to move it around.

The Nautilus T614 Treadmill comes with most features that you would need. The motor is powerful enough for most users, and the speed height is good too. The incline is strong, and the display is better than lower end models.

However, as I mentioned before, most treadmills sound good on paper, and they perform well too–it’s just that when the product malfunctions, is when you start understanding what the real product is. So, is the Nautilus T614 Treadmill reliable or not?


Nautilus T614 Treadmill Review

The Nautilus T614 Treadmill has a decent warranty policy, but it might not be as good as you would think. At first glance, it covers a lot of important features. The warranty covers a ten-year term on the frame, motor, two years mechanical parts, two years electrical, and 90 days labor. This is an oddly specific warranty since most treadmills cover lifetime warranty on frame, motor, and deck. These same treadmills also include five-year warranties on parts.

Ten years is decent, however, since the treadmill is only $700-800 instead of $1400+ like the treadmills which have the best warranties.

The questionable part about the Nautilus T614 Treadmill is that a majority of the recent reviews seem to have problems with the treadmill. Like most products on Amazon, a majority of people agree with the good reviews, but the bad reviews are where you need to take note. In this case, many people have had to reservice the treadmill multiple times only after the short period, and an equal amount have problems setting up the treadmill and getting it to work.

One user we found installed the treadmill to find that the screen didn’t work, while another found that the belt didn’t work after setup. Many others claim the product arrived late and broken upon opening the package itself.

Nautilus doesn’t seem to honor repairs and warranty claims very strongly, standing behind the specific limits on the warranty. 90-day labor isn’t much, and if you have problems with the treadmill, it’s going to be a huge hassle to fix it.

Nautilus T614 Treadmill Review Conclusion

The Nautilus T614 Treadmill is another treadmill we’ve reviewed on Amazon to make the same conclusion. If you’re at a certain price point, like the Nautilus T614 Treadmill is, it seems like the warranty and customer service just can’t be enough to stand by what sounds like good products on paper.

Tons of poor customer reviews, as well as our analysis of the warranty, make the Nautilus T614 Treadmill out to be not a reliable treadmill. Features and specs aside, the Nautilus T614 Treadmill seems to be a risky purchase for what can still be considered a hefty amount of money.
