Differences Nautilus E616 vs Sole E25 explained in detail
If you are familiar with elliptical machines and know what you want in them, the table of differences and a quick look at the prices could be enough to decide between the Nautilus E616 and the Sole E25.
On the other hand, you may also still be unsure about what certain features mean or why they are important.
You can find some of the most confusing differences explained in more detail below to be able to make an informed decision.
Incline options
Elliptical machines sometimes have the option to raise the front part to different levels. Both the Nautilus E616 and Sole E25 have incline options like this but to what angle you can go varies.
More precisely, the Nautilus E616 can go up to 10 degrees of incline. The Sole E25 has 20 incline levels and mentions this results in an incline of 30 degrees.
Some of the effects of incline ellipticals include engaging your muscles in a different ratio, adding some variety, and making certain workouts feel more immersive.
Whether you like the extra incline options of the Sole E25 and to what extent they matter depends on things like your training goals and personal preferences.
In any case, the Sole E25 does have the advantage in this area.
Winner: Sole E25
Flywheel weight
A flywheel of an elliptical machine is the rotating disk the pedals are attached to. This part can vary in a few areas including weight.
The Nautilus E616 has a flywheel weight of 17 lbs (11.3 kg). The flywheel of the Sole E25 is a bit heavier with a weight of 20 lbs (9.1 kg).
A general guideline is that heavier flywheels tend to be preferred. The first reason for this is that heavier flywheels build up more momentum.
In turn, this results in less risk of interrupting the rotations when/if you don’t apply pressure on the pedals perfectly.
Additionally, heavier flywheels are a tiny amount more challenging to get and keep going. Mostly in the forward pushing and backward pulling parts of the rotations.
However, you should not expect too much from this because the extra momentum of the heavier flywheel helps you.
The difference in flywheel weight between these two elliptical machines is relatively small. Most people will not really notice the difference.
That being said, the Sole E25 does again have the advantage.
Winner: Sole E25
Resistance levels
One of the main principles of exercise and more specifically elliptical machines is challenging your body enough. By doing this, you start internal processes that can make you fitter and happier in the long term.
At the same time, you also don’t want to challenge your body too much. In the best case, this can reduce the quality of your workouts. In the worst case, this can lead to injuries.
To allow you to train at the right challenge level, elliptical machines typically come with adjustable resistance.
The Nautilus E616 has 25 resistance levels. The Sole E25 “only” has 20 resistance levels.
This difference can mean a few things. The Nautilus E616 could offer more challenging workouts, less challenging workouts, or simply offer more precise choices from the same resistance range.
Besides a few cases where the resistance adjustment does not work perfectly, there are not really any customer mentions about this area so it is hard to tell what differences mostly apply.
In terms of total resistance levels, the Nautilus E616 does have the upper hand.
Winner: Nautilus E616
Price
Both of these elliptical machines have their advantages and disadvantages. Something that could make choosing between the NordicTrack E616 and Sole E25 easier is any big price differences.
Exactly how much each machine costs depends on where you get them and can change over time. That being said, at the time of writing, the Nautilus E616 is a nice amount more budget-friendly than the Sole E25.
Winner: Nautilus E616
User reviews

In the case of the Nautilus E616, a lot of the issues are around the Bluetooth connectivity and screen. There are also a few faulty parts and cases of wear and tear.
For the Sole E25, the main areas that can use improvement are the number of cases with faulty parts and wear and tear. There are also a few mentions about the machine being heavy and the display being basic.
You want to keep the things above in mind but overall customers still tend to be somewhat positive about both the Nautilus E616 and the Sole E25.
Is the Nautilus E616 or Sole E25 better for you?
In short, the Nautilus E616 has more resistance levels, more built-in workout programs, a lighter weight, and a price that is a nice amount more budget-friendly.
On the other side, the Sole E25 has a higher weight limit, more incline options, a slightly heavier flywheel, resistance and incline controls on the moving handles, and longer warranties.
What model you want depends on your personal preferences and budget.
People who want more resistance levels, like the variety of many different workout programs, and/or want to move their machine around a lot will likely prefer the Nautilus E616.
This elliptical machine is also simply a good option at a relatively budget-friendly price.
People who have an above-average body weight (for now), like the highest incline options, want a slightly smoother workout, like the convenient adjustment buttons, and don’t mind investing a bit more can consider the Sole E25.
