What a better way to ease yourself into following a workout routine than having a treadmill right at your home? This way, commitment should be less of an issue, as you can’t just use bad weather as an excuse anymore for not hitting the gym.

Picking the right treadmill to fit your needs can be a bit of a hassle, though, as there are plenty of different options to choose from. Sole treadmills stand out among the bunch with their feature-packed, affordable models that suit all budgets and fitness goals.

Buckle up as we navigate through Sole’s folding treadmills line-up and highlight how different models compare to one another to help you make an informed purchase decision.

Overview of Sole Treadmill Features

Sole treadmills are well known for their durability and exceptional build quality. Such defining features remain relevant across the entire line-up. This means you won't have to give up the quality even when opting for the budget models.

Furthermore, pricing is another area where Sole manages to get things right. Even with all the features and technologies baked into its treadmills, Sole delivers affordable packages, helping the company maintain a competitive footing in the fitness market.

The appeal for folding treadmills can't be understated, as they help you save space in your home while providing the very same benefits. Sole capitalizes on their convenience and compact folded footprint by implementing a unique, user-friendly folding mechanism for its treadmills.

Sole’s Easy-Assist technology uses a hydraulic system, allowing you to fold your treadmill open with a single lever press and unfold it back with one hand. The treadmills also come with four wheels, instead of only two found on similar ones. This makes it easier to move your Sole treadmill between rooms and dock it back in a corner after you’re done with your workout for the day.

Finally, you get extra features like built-in training programs, an intuitive console with easy to reach controls, and a high-quality motor with a dedicated cooling system to prevent overheating during extended workout sessions. 

The main distinctions between different models all boil down to the motor’s horsepower, weight capacity, console-setup, and running surface. So, this is where we’ll be focusing our attention when comparing Solo folding treadmills.

Sole F63 vs Sole F65 Treadmill Comparison

Sole Treadmill Comparison: F63 vs. F65

Let’s kick off our comparison with two of Sole’s most affordable folding treadmills: the Sole F63 and Sole F65. The two share many of the same fundamental features, with the F65 having the edge in some areas as it’s the newer model.

In terms of construction, the two treadmills come in a steel frame with rust-resistant powder coating. Such a durable chassis ensures you don’t run into any reliability issues, as it’s built to last. The F65 takes durability to another level with its two-ply reinforced belt, adding extra impact resistance.

Speaking of impact, both models fully adopt Sole’s CushionFlex Whisper Deck technology. It aims at reducing tension on your joints by 40% compared to running on paved roads. This is a big deal, as the force generated during running can be as high as three times your body weight, causing joint stress, especially on the knees.

The belt on the Sole F65 treadmill also has slightly wider rollers, sitting at 2.5 inches. In theory, this contributes to a quieter operation, but we didn’t notice much of a difference in the noise level while testing it alongside the F63. Still, the broader rollers relieve some force off the treadmill’s motor, which is always a welcome addition.

As you might expect, the motor on the newer F65 comes with more horsepower. It has a 3.25 CHP rating as opposed to 3.0 CHP on its F65 counterpart. Both models can achieve the same maximum speed of 12 mph with an inclination of up to 15%. However, the more powerful motor can fare better in vigorous, extended workouts.

Another distinction between the two, which actually makes a noticeable difference, is the belt’s dimensions. You get a 22 x 60 inches running area on the F65, compared to 20 x 60 inches on the F63. The 2-inch width difference might not sound like a lot; nevertheless, during running, you’ll notice that you now have a broader area to stretch your legs.

Another point to bear in mind when picking one treadmill over the other is weight capacity. The F63 is limited to a maximum of 325 lbs, while its newer iteration bumps the weight limit to 350 lbs thanks to its beefier motor and wider rollers.

Now that we’ve covered all the basics, let’s review some of the extra features that can make your running sessions more convenient. 

For starters, the F63 and F65 have two cup holders, allowing you to keep your favourite beverages within hand. They also come with a tablet holder to watch your favourite movies while you’re working out. 

The experience is further enhanced thanks to the treadmills’ built-in speakers. Furthermore, Bluetooth functionality offers useful connectivity features, enabling you to sync your metrics to Sole’s mobile app, so you have a better visualization of your progress.

It’s also worth mentioning that the F63’s console offers a 6.5-inch LCD, while the F65 comes with a bigger 7.6-inch display. Though the smaller LCD gets the job done, the bigger screen is a joy to look at. It provides better visualization of your workout’s data, allowing you to know how much time you have left.  

Finally, the handgrips serve more than just boosting your stability while running. They house pulse monitors that give you real-time insight into your heart rate and burned calories. If you want even more accurate heart monitoring, you’d be pleased to know that the treadmills are compatible with chest straps.

Now that we’ve established the main features that you need to keep an eye on when choosing a treadmill, let’s explore some of the bells and whistles that Sole has implemented in its more expensiveSole F80 treadmill and see how it fares against the F65.

The most significant changes lie under the hood, as the F80 packs a much powerful motor with a 3.5 CHP rating. Though it’s still considered consumer-grade, the motor in the F80 tips closer to the professional territory than its F65 predecessor. If you’re planning to push yourself to the limit, the more powerful treadmill is the way to go.

Though you still get the same 12 mph maximum speed, you can enjoy longer jogging or running sessions without the Sole F80 treadmill ever breaking a sweat. Also, the extra horsepower helps push the weight capacity to 375 lbs. So, your current weight can be an important determining factor in picking the F80 over the F65.

You might think the powerful motor is likely to make your F80 sound more like a jet engine under your feet. This is far from the reality, as the treadmill keeps a silent profile thanks to the unique motor design that goes hand in hand with the well-thought-out belt assembly.

The belt uses the same design elements we’ve seen in the F65. The two-ply reinforcement and the wide 2.5 inches roller deliver a more stable running surface with less wobbling on impact. Also, the F80 keeps the same 22 x 60 inches running area to ensure your feet don’t feel crammed together on the treadmill.

However, it's worth mentioning that athletes coming to the F80 as a more affordable alternative to the flagship, professional-grade treadmills might be disappointed. The 60-inch length isn't enough for serious runners. You'll need to readjust your stance and keep yourself closer to the hand grips, especially when you're running at high speeds.

Understandably, the F80 can't go all-in in terms of its belt dimensions, as it needs to keep a manageable form factor that can be easily folded and unfolded. As far as best treadmills for home use go, 22 x 60 inches should work fine for most people.

Furthermore, the Sole F80 treadmill offers an even larger display with its 9-inch LCD that’s a substantial upgrade over the F65’s 7.6-inch screen. Aside from the screen real estate, the F80 uses a back-lit TFT panel, which delivers sharp text and higher brightness for more viewing angles. 

The larger screen gives you more data to glance at, so you don't have to cycle through different tabs to view more data about your current workout. The F80 also keeps the tablet stand, giving you the means to pass the time while you're burning calories.

The F80 knocks it out of the park with its post-purchase support. You get a lifetime coverage on the treadmill’s main parts, including the frame, belt, and motor. That’s not all; you also get a 5-year warranty on all the electronics and replacement parts, in addition to 2 years on labour.

Compare this to the 3-year warranty on electronics, parts, and deck offered by the F65, and you start to see how the more expensive model goes the extra mile to ensure your investment is protected for years to come.

Sole F80 vs Sole F85 Treadmill Comparison

Sole Treadmill Comparison: F80 vs. F85

We’ve come to the end of our in-depth comparisons, and this time around, we’re putting the F80 toe to toe with the flagship Sole F85. Being the newer model, it comes as no surprise that the F85 has a hefty price tag to match all its advanced features. If you’re looking for the latest and greatest from Sole’s foldable treadmills, the F85 is the right pick for you.

Right out of the gate, you’ll notice that the F85 comes in a larger form factor. This can be a deal-breaker for people who have limited space in their homes. On the other hand, the 35 x 80 inches running area is exactly what others are looking for. 

The expansive belt lets you pay less attention to where your feet are landing and focus more on crushing your numbers. This can be especially useful for professional runners and larger individuals who struggle with keeping their balance on the relatively compact dimensions of the F80.

Even at this considerably larger footprint, the Sole F85 maintains the same seamless folding system. The hydraulics kick into action, allowing the treadmill to gently unfold with a tap of a button. This system also keeps folding the treadmill back in place, a one-handed process with minimal effort on your end.

With every new iteration, we get a bump to the motor’s horsepower, and the F85 is no exception. Here, you get a whopping 4.0 CHP worth of motor power that manages to keep the same inaudible, quiet profile that the previous Sole treadmill models deliver.

Another upgrade comes in the maximum weight capacity. The F85 supports up to 400 lbs as opposed to 375 lbs seen in the F80. This opens up the doors for more people to start working out and pursue their fitness goals. There's no excuse now, as you have all the tools to turn your life around.

Furthermore, the F85 comes with ten fitness programs to choose from. This includes two cardio and two customizable programs for you to tweak according to your goals. All the previous Sole models only provide you with six, which is also a decent sum.

The Sole F85 packs a high-quality 10.1-inch LCD, which is put to great use as you get real-time metrics on your heart rate, current speed, average speed, travelled distance, and much more. If you’re training for a race, you can set up a given pace, and the treadmill will alert you if you exceed or fall short of it.

The heart monitoring capabilities are possible thanks to the built-in sensor in the grips. Just like other Sole treadmills, you can use more-specialized chest electrodes to record accurate heart activity.

Another welcome addition is the inclusion of a strap that you can wrap around your chest. This helps you keep a stable stance, especially if you’re running at high speeds, and one missed step means you’ll trip over. This added layer of safety ensures you can pursue your fitness goals without hurting yourself.

For added comfort while running, you also get built-in cooling fans. People who have limited space will appreciate this feature, as after unfolding the already massive treadmill, there might not be enough room for your regular fan. 

When it comes to post-purchase support, the F85 keeps the same impressive F80 warranty program, giving you peace of mind for years to come.

Conclusion: Which Sole Treadmill Is Right for Me

By now, you should have a solid idea about which Sole folding treadmill makes the perfect fit for your fitness needs, house setup, and budget. No matter which model you opt for, you’re getting a great value, as Sole undercuts the competition in each price range.

Furthermore, Sole’s DNA remains intact throughout its entire line-up, as the company goes the extra mile to ensure its fitness equipment lives up to its high-quality standards. If the durability claims aren’t enough to convenience you, Sole offers a warranty on top of your purchase. This shows how much the company is confident in its treadmills.

If you’re still torn between two models, we’ll help you get to the bottom of it. The F63 is perfect for people who are on a tight budget. It comes with a decent enough motor that supports a weight capacity of 325 lbs and comes in a relatively compact form factor, making much sense for people with limited indoor space.

Moving on to the Sole F65 treadmill, you get a higher weight capacity of 350 lbs, thanks to the more powerful motor. You also get a wider running area for your feet to move more freely. That said, the F65 is perfect for larger people looking for a more comfortable running area without committing to the higher price tag of Sole’s higher-end models.

The Sole F80 treadmill finds itself in a weird spot, as it keeps the same running area as the F65 but comes at a higher price. The only incentive to upgrade is to make use of its 3.5 CHP motor that pushes the weight capacity to 375 lbs.

Finally, the F85 is a complete package. It offers a running area of 35 x 80 inches, which is what professional athletes are looking for. It's also perfect for larger individuals as it supports up to 400 lbs and offers a chest strap for added stability while running.

It's worth noting that the 10.1-inch display is the largest on any Sole treadmill we've reviewed. This can be a selling point for people who are serious about tracking their progress and want all the essential metrics to be laid out all at once on the screen.

Both the F65 and F80 are fantastic options for athletes who prefer to run at home. However, the F65 is considered more budget-friendly. Its motor is slightly weaker, which results in a reduced maximum weight limit, and it still uses the conventional LCD backlit display.
