Further down the page, you’ll find some explanations regarding the key similarities and differences between the Nautilus T618 and the Sole F63.
But before checking out explanations regarding their specs, features, and warranty, here’s a table that summarizes the main technical summary sheet for these 2 treadmills:
The T618 at $2149 is rather on the costly side, while the latter at $1470 is much more affordable. The price gap is so big that it may greatly affect many customers’ buying decisions.
Both models give out a max speed of 12 MPH – a standard speed range at most treadmills. They are exactly right for you if you wish to intensify your workouts in a moderate way.
The Nautilus T618 supports a user weight capacity of up to 350 lbs, whereas its rival holds one of 325lbs. With many models only able to carry a 300-lbs person maximum, these two are just incredible. Particularly, the T618 is suitable for the tallest and heaviest runners.
Plus, it also offers a huge-sized motor of 3.5 CHP, 0.5 CHP stronger than the latter one. Users will have enough power to run at high speeds without having the motor worn out. One thing to note is that the 3.0-CHP F63 is not as good at handling heavy training as the 3.5-CHP.
As powerful as the T618 treadmill is, we can notice a humming sound when activating this machine. Don’t worry! The noise is quite even, thus you’ll soon forget about it.
They both feature 15% incline adjustability, allowing you to run uphill and challenge your fitness. The large incline degree option can give you a hand to burn serious calories faster.
In terms of onboard programs, the F63 offers ten simple workouts, like a manual, fat burn, or cardio. Not bad, but this may be underwhelming compared to its competitor. There are 26 built-in programs on the T618, including heart rate training, weight management, and interval workouts.
Either the T618 or the F63 are equipped with two small Bluetooth speakers. Their sound quality is quite good and we can rarely experience degradation at high volume levels. Users can enjoy their favorite melodies while running hard.
Besides, the two treadmills provide users with convenient storage. Their consoles contain two pockets on either side of the screen. They also come with a USB charging port and a tablet holder. Consumers can charge their smart devices and watch an action movie while exercising!
The Nautilus treadmill holds a basic LED display, which lets you view your workout metrics. Meanwhile, the Sole F63 includes an integrated White Back-lit 6.5″ LCD screen. You can read digital numbers easily with this generous screen size and set up programs with the below buttons.
The Nautilus company covers your purchase with a lifetime frame & motor warranty, 3-year parts & electronics warranty, and 1-year labor warranty. Besides, the latter offers a labor warranty of 2 years, parts warranty of 5 years, and motor & frame warranty of 15 years.
Although the T618 comes with various types of assurance, its labor warranty is way skimpier than other models in the same class.
Nonetheless, one thing for sure is that once you’ve bought either of them, you got a treadmill that will go with you for years after.

Frankly, our model of choice is the Nautilus T618. It has shown off wider speed options, larger incline range, greater weight limit, huger horsepower motor, and more.
Many may hesitate to buy this one due to its price. But one thing to keep in mind is that you get what you pay for. In our opinion, the machine is beyond our expectations for the price it is offered at.
Nevertheless, we consider the Sole F63 is not a bad idea for entry-level runners. Walkers or joggers seeking a fold-up functional machine can also take this model into account.
