The Nautilus T614 treadmill exists in a class that isn’t discussed as often as the usual two. Most 
frequently, discussions revolve around either high end, professionally-targeted machines that can cost up to $5,000 or budget designs in the “under $1000” range.
The T614 settles in neatly between these price points at just shy of $1500, offering a combination of sensible price and worthwhile features that should make it a serious consideration for the home fitness enthusiast.

Technical Info
Let us begin by reviewing the meat and potatoes of any home fitness device review, the technical specifications of NautilusT614.
- Height: 57.6” (145 cm)
- Width: 35.2” (89.4 cm)
- Length: 72.2” (183.4 cm)
- Weight: 200 lbs (90.7 kg)
- Running Surface 20” x 55” (50.8 cm x 134 cm)
Put another way, Nautilus T614 is nearly five feet tall, three feet wide, and six feet long. These dimensions might seem intimidating at first, and they are substantial, but they track very closely with other treadmills, and are indeed smaller than some of the high-end machines such as those found in certain gyms (particularly in width).
Features
For ease of reference, let’s divide the Nautilus T614 treadmill’s features into those of the machine itself, and the on-board computer system.

Workout Data
As with most treadmills above the $200 price range, the Nautilus T614 treadmill offers a variety of tracking features that break down the specifics of your workout. As you know, we love metrics here, because they help make vague goals like “lose weight” into more concrete, measurable data sets.
The Nautilus T614 Treadmill tracks:
- Your selected workout profile
- The average zone your heart rate enters
- The name of the Active User
- Time per lap
- Distance covered per lap (count)
- Calories Burned
- Heart Rate/Calories
- Incline percentage
- Overall speed
These are, admittedly, fairly standard measurements, but they are important to anyone’s goals if measured properly. The profile system makes it easy to compare a current workout to previous efforts, giving users a solid sense of where they have come in their exercise journey.
Warranty
No machine is perfect, so the warranty specifications are important to check out. Nautilus has offered the following warranty with their T614 treadmill.
- Frame: 10 Years
- Motor: 10 Years
- Mechanical: 2 Years
- Electronics: 2 Years
- Labor: 1 Year
Shipping and Assembly Details
It is important to stress that Nautilus does not sell the T614 treadmill directly to consumers. You cannot order it from their site for direct delivery. Instead, you must go through a third party vendor, and arrange shipping and assembly through them.
This makes it impossible to discuss the matter of delivery and assembly in detail, as every retailer or vendor will have their own policies regarding these matters. So above all, make sure you receive a concrete answer, in written or electronic form, regarding the delivery and assembly policies of your chosen supplier for your Nautilus T614 treadmill.
On to the Opinions:
The details are worth having, but what did we THINK when we evaluated the T614? That’s what you’re here for, after all!
The Good:
For its price point, the Nautilus T614 is positively packed with features and options. We acknowledge that 
metric tracking is becoming more widespread and standardized from device to device, but the T614 makes the process quite straightforward and integrated, rather than an afterthought or something the user must work hard to get at.
As an example, the display screen is a well-lit, well-positioned device, entirely backlit for ease of viewing. There are other workout machines in a similar price point that have failed to grasp that backlighting is now industry standard for modern electronics, preferring instead a screen that a 1990s Game Boy would feel a bit embarrassed to showcase.
Wireless integration is becoming more important, with fewer users consenting to be restrained by wires and cords if they aren’t necessary. The support for wireless monitoring is a sign that Nautilus understands that even at the low-middle price range, this is a feature that needs to be included for proper metric workout analysis.
The cushioned and quiet running surface makes this machine a pleasure to work with. No hard sensation of slamming down the feet with the Nautilus treadmill. Running is inherently high-impact, so reasonable steps to mitigate it are very welcome in an otherwise reasonably inexpensive machine.
The Not So Good:
It isn’t too technically difficult to work in a negative incline, to simulate the process of running downhill. 
This is a great way to cool off, and adds variety to “hills” style running segments. This makes the omission on the T614 somewhat baffling.
While we do praise the support for various wireless functionality, the Nautilus doesn’t come with the wireless chest strap that its programming is meant to support. This has to be purchased separately!
There’s nothing quite as bad as incremental transactions. What’s the phrase? The first taste is free? Well in this case, you don’t even get the first taste. We feel that if the system is going to include this functionality, it should have included the strap.
Lastly, the warranty made our eyes pop a bit.
Many other treadmill manufacturers will offer a lifetime warranty on the frame or other components of their devices, but the Nautilus tops out with a 10 year warranty on two categories, with drastically reduced warranties for other elements of the T614, with only 1 year covering labor!
This increases some of the risk to the consumer, and it is important that you know this in an honest review.
Final Verdict: Is Nautilus T614 a Reliable Machine?
It can support a decent amount of weight, can fit into many budgets, and has an array of features that a dedicated user can take good advantage of.
Those looking for increased features for a moderate price bump would do well to consider the T616 model, but the differences come down to a matter of preference, rather than a no-brainer decision.
