Nautilus T614 Treadmill Review

Nautilus Logo

Brief Overview

The Nautilus T614 Treadmill is an entry-level model offered by the company. It engages with the affordable bracket of workout equipment in the industry. It is another folding model with all the fundamental specifications but an overall lapse in quality and luxury features as compared to its counterparts like the T616. 

The T614 caters to customers who are looking for a convenient and satisfactory workout experience. It does not check off all the boxes for users who are looking for a sophisticated, elite workout ambiance. It is powered by a motor with a capacity of 2.75 CHP.

The inclination range for the machine is from 0 to 12 percent. It is equipped with a hefty weight capacity, comfortably sized running area, backlit display system, and an adjustable cooling fan to deescalate the body when required. 

It offers a variety of 22 built-in programs to choose from to intensify and diversify your workout routine but only two of those are customizable. 

The Nautilus T614 treadmill Review has identified its pros and cons when compared to other models in the same bracket. Continue reading below to get a fair idea of those pros and cons and whether the buying decision is recommended.

Nautilus T614 Workout

Detailed Overview

We can observe and rank the Nautilus T614 treadmill under a different lens to help users evaluate their treadmill purchase.

Basic Machine Function – The 2.75 CHP Motor

Released in the 2015 collection, Nautilus T614 provides a satisfactory range of machine functions for weight loss and fitness training. The 2.75 CHP motor is a good one but definitely not among the most powerful ones with horsepower going up to 3.0 and 3.5 CHP.

The noise produced is not excessive but still significant. It ticks off the walking, jogging, and running requirements of an amateur user. 

The Running Area

The running belt is sturdy and spacious enough for functional use. A weight capacity of higher than 300lbs might also be demanded at a price like such. The running speed of 12 miles per hour is more than ordinary products available in the market but again not among the best ones either and secures a safe place in the medium category. 

The deck of the T614 is a bit springy. Walkers or joggers who like firmer decks might consider this a turn-off. But this ideal for someone who likes flexible decks.

Nautilus T614 Strike Zone Cushioning


It has SoftDrop Folding Technology which makes the design desirable and is attractive for easy storage use. The running area of 22 x 55’’ is not enormous and makes for a manageable shape and size. 

The machine measures up to 200 lbs and is not one of the sleek, modern models. The structure of T614 is generally stable and avoids any risk of wobbling even at higher speeds.

Safety Features

The safety and security features of workout equipment are factors customers especially take into account when choosing the perfect machine.

The Nautilus T614 treadmill does not have password protection or other deluxe security features that modern elliptical and treadmills facilitate. Nevertheless, it does contain a safety key and tether cord that will connect an article of your clothing to the machine. 

The cord would detach and cause a predetermined stop in the case of a fall or moving too far from the console.

The heart rate sensing in T614 is possible only when contact is constantly made with the sensors. Hand-free heart rate monitoring is possible but the wireless chest strap must be bought by the customer independently.

Display Features

The extra-large high-resolution blue backlit LCD monitor has a variety of sub-features like performance tracking and goal setting. These lights will illuminate once a record distance has been touched.

The console entails a 3-speed cooling fan, incline controls, convenient speed control, and a matrix profile of the currently chosen workout program.

The features are impressive but the LCD display is a bit overcrowded, making it difficult to read, especially while running.

Workout Programs

The average number of workout programs for a treadmill in this price point is usually 26 but the Nautilus T614 treadmill offers only 22. The 22 built-in programs are distributed into 16 subsets which automatically set the machine to a particular predetermined speed and incline level. 

The categories of workout programs in T614 are Heart Health, Quick Goals, Weight Control, Train, Custom, and Interval. This is a lucrative luxury feature in a machine in this price bracket but the user profile is limited to two users.


The warranty constraint is a central issue of the T614. It does not have a lifetime warranty like some of its esteemed counterparts and other models offered by Nautilus itself.

The warranty of the motor and the frame are limited to an unsatisfactory 10 years while 2 years warranty is offered on the mechanical and electronics. This can be deemed a red flag for the customer who craves a lifetime warranty when investing in equipment like such.

Price Range

Customer and expert reviews have shown that the quality of the features does not justify the price and the price should be lower in the 700s line. It has room for progress in the motor capacity, speed, console features, design, and warranty. The average for incline ability is also observed around 15 while the T614 is restricted at 12. 

Some Cons of the T614 Treadmill

The running area of T614 is 55″ by 20″, which is small for the taller runners. Also, the maximum user weight capacity is only 300 lbs, while the market-leading treadmills offer a much higher max weight capacity. The incline range is also up to 12% only, while most treadmills go up to 15%. The motor of the T614 is slightly underpowered at 2.75 CHP while most treadmills at least have a 3.9 CHP motor. These are some of the reasons why the main specs have only been rated at 6/10. 

Is Nautilus T614 Treadmill the workout partner you are looking for?

Although the Nautilus T614 treadmill strives to compete in the product line ranging in the 900s and will satisfy you on some basic fronts, it does not deliver value to the extent that it should. Its build quality and features have only been rated at 7/10.  

You will be better off choosing an alternative in the same price range. That would be the rational choice given the additional qualities and specifications that the competitors offer at the same price. 

Nautilus will have to up its game in performance and supplementary features to receive traction from customers in this category in a market with players like Octane and Bowflex.
