Nautilus T616 Treadmill

Thanks to a SoftDrop (TM) folding design, users can use and store their treadmill easily. T616 model is equipped with transport wheels which allow you to move this trainer anywhere you want.

Besides, another feature Nogii has to mention here is that these treadmills of Nautilus are quite compact and lightweight.

With a 25 mm deck, these T616 models can support runners weighing less than 300 pounds.

Besides, you don’t need to worry whether the deck is too rigid.

Nautilus T616 integrates StrikeZone cushioning system with six hexagonal suspension cells. It ensures a comfortable and smooth operation when you walk, jog or run on T616 treadmills.

When it comes to incline, the tilt range of the T616 is from 0% to 15%.

Although almost all of the commercial-grade treadmills provide 30% or more incline, a 15% incline is suitable for Nautilus T616 when you use it at home.

Because it is a motorized incline system, you need the machine’s console with gradual and quick adjustment keys.

Nogii highly appreciates a 3.0 CHP, the industrial motor in this case. The T616 performs excellently when users run at high speed for a long time. The motor works continuously without overheating.

Nautilus treadmills use heart rate monitoring through pulse grips and included chest strap.

MP3 compatible sound system and USB charging port bring the most convenient experience which keeps you entertained during your training session.

Additionally, users can adjust the 3-speed cooling fan to keep themselves cool and dry.

Computer Features

Nautilus T616 treadmill offers 26 programs, including 1 Goal, 1 Quick Start, 18 Profile Programs, 4 Heart Healths, and 2 Fitness Tests.

With a wide variety of programs, it is easy to find one that works for you.

Is it enough? Wait, there’s more!

If more than one person uses Nautilus T616 or you want to set different goals at the same time, four unique User Profile programs will help you.

Users Profiles will suggest the most suitable workout plan. Also, you can know your fitness level after the completion of each workout.

Nautilus T616 Treadmill Review

Is the Nautilus T616 model worth your money?

Yes, it is.

From our perspective, with a price under $1000, the T616 has outstanding features of an excellent treadmill as we expected.

A powerful motor, a durable deck, a multi-functional console, folding design, Bluetooth and USB connectivity, impressive tracking, and various workout plans – you can find what you need in a Nautilus T616.

However, this treadmill still has some problems which Nautilus needs to improve in the later model.

One of the most common complaints about the T616 is the warranty.

Nowadays, almost all treadmill brands provide lifetime warranty at least on the frame. Whereas, Nautilus only offers a 10-year warranty on the frame and the drive motor and a 3-year warranty on parts.

Besides, we find the console fairly crowded with too many buttons and adjustment keys. Also, it is a bit difficult to read two small display screens of Nautilus T616 treadmills.

The cooling fan is small, too. We realize that it doesn’t work effectively for prolonged workout sessions.

Let’s take a quick look at the pros and cons of Nautilus T616 models!


  • Solid overall construction
  • Strike Zone cushioning system for a smooth run
  • Reliability, high responsiveness, and excellent performance with 3.0 CHP motor
  • Soft Drop folding system
  • A rugged professional-grade 20″ x 60″ deck
  • A console assisted, motorized incline system: 0% – 15%
  • Built-in input port for MP3 players and USB port
  • Easy assembly
  • Various amenities: Chest strap, sound system, cooling fan, USB charging port, 2x bottle holder
  • Heart rate: Contact & telemetry enabled (Chest strap included)


  • Unimpressive warranty
  • Crowded and small display screen
  • Ineffective cooling fan

Comparison: Nautilus T616 Vs. T618 Treadmill

Although the T618 is the later model of the Nautilus residential treadmill, there are no significant differences between Nautilus T616 and T618.

However, perhaps some small changes in the T618 are what you find the most suitable. Let’s see what makes two products different!


While T616 treadmills use a 3.0 CHP motor, T618 treadmills are equipped with a 3.5 CHP one.

As a result, T618 models have a higher weight capacity with 350 lbs.

If you require a sturdy treadmill which can withstand continuous and prolonged running workouts, T618 is a better choice.


The warranty for the Nautilus T618 is 15 years for the frame and drive motor, 5 years for mechanical parts and electronics, and 2 years for labor.

When we compare two models, we realize that Nautilus has made an effort on the improvement of the warranty on their products.


You can see that the cost of the Nautilus T618 treadmill is higher than that of T616.

The money you need to pay will determine what you get.

If a robust treadmill with more extended warranty meets your demands, you should opt for Nautilus T618. However, if your budget is tight and you cannot afford a luxury treadmill, our best suggestion is the T616 model.

Jump To An End

Nautilus T616 treadmill is a great combination of solid construction and powerful functions. With a reasonable price, this model becomes an ideal choice for both beginners and professional runners.

No matter what your goal is, cardio training, muscle strengthening or weight loss, T616 treadmill is an excellent piece of equipment you need.
