Nautilus E614 Review

The Nautilus E614 Elliptical Trainer is an entry-level home use / light commercial elliptical trainer. It is aimed at users who are looking for a basic, reliable, sturdy elliptical, and are not concerned about missing out on features included in more expensive machines, such as Bluetooth connectivity, heart-rate monitoring, and power-adjustable incline.

Build Quality

Nautilus is known to manufacture strong and durable elliptical machines. The E614 is no different. Weighing 167 lbs, the machine utilizes steel tubing for a steady frame. Parts like the handlebar and the cushioned footplate use materials that provide additional durability so users can expect to use the machine for years in comfort. 

Weight Capacity

The Nautilus E614 Elliptical has a maximum weight capacity of 300 lbs. If you weigh over 300 lbs, you will need to consider another machine. 

Adjustment Range

To allow users to continuously build up their workouts, the E614 comes with 20 levels of resistance. Most users will find themselves on one level for weeks before they move up to the next one. The machine also comes with 12 pre-programmed workouts for you to go through. Selecting a workout is as simple as pressing a couple of buttons, and before you know it, you are on your way to a healthier body. 

The machine also gives users the option to add some incline. There are six levels of incline that can further intensify your workouts. It does come with a catch, however, in that you have to set the incline manually – you need to stop your workout, get off the machine, physically change the incline, then re-start your workout.


The dimensions of the Nautilus E614 Elliptical are 63.2 x 26.7 x 71.5 inches. You can easily find space for the machine in any room of your home.


The Nautilus E614 Elliptical has a high-tech design that fully utilizes technology. It comes equipped with a DualTrack LCD window system. The system uses two LCDs to allow users to track their workout while they read or enjoy watching a video on their tablet. 

As far as tracking goes, it provides users with ample data such as heart rate, calories burned, as well as other necessary fitness data. You can also export your data using Nautilus Connect. That way, you can access it whenever you like.


You get a step-by-step guide with the Nautilus E614 Elliptical that does attempt to simplify the assembly process. However, the instructions are somewhat confusing. There are a lot of moving parts in the machine, which makes assembly a long process. It should take anywhere from 2-3 hours to assemble the machine. 


The Nautilus E614 Elliptical has a decent price tag for all that it offers. It is a high-tech elliptical that makes workout both enjoyable, with its DualTrack LCD, and challenging, offering 20 levels of resistance. It is a wonderful companion for anyone working to either achieve or maintain a healthy lifestyle.

Nautilus E616 Review

The Nautilus E616 Elliptical Trainer is a mid-range home use / light commercial elliptical trainer. It is aimed at users who are looking for a basic, reliable, sturdy elliptical, with more included features than the basic models, such as Bluetooth connectivity, heart rate monitoring, and power-adjustable incline.

Build Quality

Nautilus is known for creating elliptical machines with a sturdy frame. For the E616, the manufacturer uses oversized crossbar tubing in the frame. This provides stability to users when on the machine, while also making it durable. It comes with a perimeter weighted flywheel to ensure users get plenty of inertia and speed during workouts. You can be sure to have friction-less workouts on the machine.

Weight Capacity

The Nautilus E616 Elliptical Trainer has a weight capacity of 300 lbs. Individuals who weigh more should consider another elliptical.

Adjustment Range

The Nautilus E616 Elliptical comes with 25 levels of magnetic resistance. That is one of the most you will find for its price point. You can adjust the resistance to the level you want and work your way to more intense workouts. With 25 levels, you will find yourself working out with this machine for years.

It also comes equipped with a motorized incline machine that provides a maximum incline of 10 degrees. The adjustment range in resistance and incline lets you get the most out of your workouts.


Height is the primary concern when picking a spot for an elliptical in your home. The dimensions of the Nautilus E616 Elliptical are 72 x 28 x 71 inches, and it weighs 198 lbs. To determine whether the ceiling in the room is high enough, add 20 inches to your height, to allow for the height of the pedals – e.g., if you are 5’10”, you will need a minimum ceiling height of 7’6″.


The design of the Nautilus E616 Elliptical Trainer ensures user comfort. The padded handlebars are adjustable, so you can position them as it suits you.

It comes loaded with a ton of features that will have you excited and looking forward to working out every day. You have 29 pre-programmed workouts to choose from. The DualTrack LCD display also ensures that you can track your progress and enjoy a video or book as you work out. To track your heart rate, there is a contact pulse grip on the handlebar, and the E616 can also read telemetry from a chest strap.


Assembling an elliptical can turn into a workout on its own. However, Nautilus provides an easy assembly guide to follow for the E616. The manual comes with large pictures with clear step by step instructions for you to follow. It also comes with all the necessary tools needed for assembly. You should have the elliptical up and running in an hour or two, maximum.


The Nautilus E616 Elliptical is a mid-range elliptical that offers users a taste of what high-end machines are like. It provides user convenience and ample features, including 25 resistance levels, DualTrack LCDs, and so on, to keep workouts entertaining and intense. You can be sure the machine will have you engaged in and enjoying your workouts every day.
