Nautilus T616 Review

Editor's Rating: 8.2 /10

This T616 model by Nautilus is the elite model in their line of residential treadmills. Inspired by their commercial-grade equipment, these models are typically sold by retailers like Dick’s Sporting Goods.

With a 3.0 CHP motor, large 2.75 inch crown rollers and a spacious running area of 20″ x 60″, the T616 is both comfortable and well-made. It is also a folding machine, equipped with a SoftDrop (TM) folding design.

This model is all about convenience and comfort. In addition to the folding design and spacious running area, this model is also designed with the StrikeZone (TM) Cushioning System, 6 hex cell design, for extra comfort. You can enjoy an incline from 0 to 15% and speeds from 0 to 12 mph, and the weight capacity tops out at 300 pounds.

Coming to the console, this is the highlight of this model. Featuring a DualTrack (TM) display, there are two high-resolution blue backlit LCD display screens that display up to 13 workout details. There are 26 built-in workout programs that feature 4 customizable programs as well as 4 user profiles to keep workout information separate. And it’s easy to store all of this workout data and sync the information right to your device using the Bluetooth-enabled console. To monitor your heart rate, you can use the contact grips built into the handlebars or you can monitor your heart rate hands-free using the chest strap that is included. There are also audio offerings that include built-in speakers, a USB media charging port and MP3 input port. This model also comes with the basics like two water bottle holders and a 3-speed adjustable fan.

The warranty isn’t great with this model, with Nautilus offering just 10 years on the frame and drive system, 3 years on mechanical and electrical parts, and 1 year on labor.

What We Like:

  • Folding Design: This model is equipped with a SoftDrop(TM) folding design so it’s convenient and easy to use and store away when you are done working out for the day. It’s also fairly compact and lightweight, and features transport wheels so it’s ideal for anyone who needs a trainer that is mobile.
  • Program Variety: It’s easy to find a program that works for you with 26 programs to choose from. Programs include 1 manual, 3 Quick Goal, 6 Train, 5 Weight Control, 4 Heart Health and 3 interval. There are even 4 customizable programs so you can personalize your workout experience even more.
  • Bluetooth Connectivity: This model is equipped with Bluetooth connectivity that allows you to sync workout data with the Nautilus Connect (TM), the Nautilus Trainer (TM) App, or the MyFitnessPal App. Nautilus Connect (TM) is an excellent performance tracking program that allows you to sync and analyze your individual workout data for advanced and easy goal tracking.
  • Incline: Target various muscle groups and work on endurance training with the 15% incline offered with this model.
  • Fully Loaded Console: This console provides pretty much everything you could ever need other than a web-enabled touchscreen or internet connectivity (but you would expect to pay more for that anyway). You have a fan, full audio system, tons of programs and an easy-to-use console. The incline keys are down the left side of the console and the speed keys are down the right side, and there are one-touch keys for functions like workout programs.
  • Six-Week Satisfaction Guarantee- If for any reason you’re not satisfied with your purchase, you can return for your money back minus shipping and handling or assembly fees. Just call customer service to receive a Return Merchandise Authorization, and the process is very straightforward and simple from there.
  • Interest-Free Financing Available- If you can’t afford the full purchase price in one payment, Nautilus offers in-house financing with interest rates as low as 0% if paid within 18 months for qualified buyers with the Nautilus Credit Card.

What We Don’t Like:

  • Warranty: You won’t find a lifetime warranty of any sort offered with the T616 model. Almost all models by almost all brands will offer a lifetime warranty on at least the frame, but this model comes with 10 years on the frame and drive motor, with just three years on electric parts and one year on labor.
  • Weight Capacity: The weight capacity for this model is a bit low at just 300 pounds. For the price and size of the motor, the weight capacity should be somewhere closer to 350 or 400 pounds.
  • Display Screen: Despite the impressive offerings of the console, it is a bit crowded and difficult to read since the two display screens are fairly small. The dimensions are also not disclosed.

Our Verdict:

In our opinion, this is a pretty good treadmill that offers something for everyone. For under $2000, you get a Bluetooth-enabled console, folding design and other performance features that make it easy to use for walking, running or jogging. The warranty is pretty shabby, but as a whole, the Nautilus T616 is a decent machine with a good amount of features and nice program variety. However; there are many other options when it comes to folding treadmills, and it’s important to find a sturdy, reliable model that won’t come with a shaky or unsteady running belt.
