The Beast Behind the Belt: Inside the Sole ST90’s Rock-Solid Frame Construction
Ever wondered what makes a commercial-grade treadmill feel different from your average home fitness equipment? The answer lies in its bones. Today, we’re diving deep into the frame construction of the Sole ST90 Non-Folding Treadmill, a machine that’s turning heads in the fitness world.
The ST90 isn’t your typical treadmill. At its core, this beast features a heavy-duty steel Z frame design that means business. Unlike foldable treadmills that need joints and hinges, the ST90’s non-folding frame creates an incredibly stable platform for even the most intense workouts.

When discussing size, we’re looking at a substantial piece of equipment. The frame supports a generous 20″ x 60″ running surface, giving you plenty of room to stride without feeling confined. The entire unit measures 70 inches long, 33.5 inches wide, and 74 inches high – dimensions that speak to its commercial-grade aspirations.
Here’s something interesting: this treadmill weighs 375 pounds. That might sound like a lot, but it’s a good thing. This substantial weight, combined with the rigid frame construction, gives the ST90 its rock-solid feel during workouts. There is no wobbling, no shaking—just pure, stable performance.
The ST90 has thoughtful design elements like a protective rear belt cover that shields the mechanism where the belt travels under the machine. These small but significant details show how much thought went into the frame’s design and construction.
The Sole ST90’s frame construction is a testament to what happens when you prioritize stability and durability over portability. While it won’t fold up to save space, its thoughtful engineering and robust build quality will give you years of rock-solid performance.
Suppose you’re serious about running and want a treadmill that feels more like a permanent piece of gym equipment than a temporary fitness solution. In that case, the ST90’s frame construction makes it worth considering.
The Revolutionary Pulley System Behind Sole ST90’s Slat Belt Design: A Game-Changer in Treadmill Technology

Ever wonder why some treadmills feel more natural to run on than others? The secret might lie in their belt design. Today, we’re diving into what makes the Sole ST90 Non-Folding Treadmill unique: its innovative slat belt and pulley system, which is changing how we think about indoor running.
The Magic of Interlocking Slats
The ST90’s slat belt design offers something unique: a series of interlocking slats that work together to create a more authentic running experience. Unlike traditional treadmill belts that use a single continuous piece of material, these slats move independently, much like the tracks of a tank – but way more sophisticated and much more comfortable for your morning jog.
Why This Design Matters for Your Workout
The genius of this system isn’t just in how it looks—it’s in how it performs. The conveyor belt-style design, measuring 60 inches in length and 20 inches in width, delivers a smooth-running surface that significantly reduces impact. Therefore, there’s less stress on your joints and a more comfortable workout, whether walking, jogging, or sprinting.
The Dual-Mode Innovation

Here’s where things get interesting. One of the most remarkable features of the ST90 is that you can disengage the belt to function as a manually powered system, similar to those curved manual treadmills you might have seen at the gym. This dual functionality is made possible by the sophisticated pulley system that allows for seamless transitions between powered and manual modes.
Maintenance and Durability: A Pleasant Surprise
If you’ve ever owned a traditional treadmill, you know the drill: regular belt adjustments, constant lubrication, and the occasional alignment check. But here’s the good news – the ST90’s slat belt design requires less maintenance while providing better traction and stability. Manufacturers build the interlocking slats to handle high-demand use, making this an investment built to last.
The Real-World Running Experience
What sets this system apart is how it mimics outdoor running. The slat belt design creates a more realistic running experience than traditional belt-driven systems. Each step feels more natural, as if you’re running on a firm but forgiving surface – imagine the perfect balance between a track and a trail.
While traditional treadmill belts have served us well for decades, the ST90’s slat belt and pulley system represents a significant breakthrough in treadmill technology. It’s not just about running on a machine anymore – it’s about creating an experience as close to natural running as possible, while providing the convenience and safety features we expect from modern fitness equipment.
The Sole ST90’s Incline System: Everything You Need to Know
If you’re looking for a premium treadmill that can handle serious hill training, the Sole ST90’s incline system might be what you’re looking for. Let’s break down what makes this machine’s elevation features special.
The ST90 has a robust incline system that offers 15 different levels, giving you plenty of options to challenge yourself. Whether you’re looking for a gentle climb or a quad-burning ascent, this machine delivers. It can maintain its impressive incline capabilities even while supporting up to 400 pounds, which is no small feat for a home treadmill.
One of the standout features of the ST90’s incline system is its responsiveness. Thanks to its AC motor, the incline adjusts faster than other Sole treadmills with DC motors, making it particularly well-suited for interval training. You’ll appreciate this speedy adjustment if you’re into HIIT workouts requiring quick transitions between flat and inclined running.

The ST90’s unique manual mode sets it apart from many other treadmills. While in manual mode, the incline is limited to 8%, but this feature allows you to power the belt yourself, similar to a manual treadmill. It’s perfect for when you want to control the pace entirely with your effort.
Engineers thoughtfully designed the incline controls for convenience during your workout. You can adjust the incline directly from the console, which features a crisp 15.6-inch touchscreen. The controls are responsive and intuitive, letting you focus on your workout rather than fumbling with buttons.
What matters is how the incline system performs during actual use. The good news is that the ST90 can maintain its top speed of 12.5 mph even at steep inclines, which is impressive for a home treadmill. Therefore, you won’t feel the machine struggling or slowing down when pushing your limits on an incline.
The Bottom Line
The Sole ST90’s incline system stands out for its quick adjustments, sturdy construction, and versatile options. Whether walking at a steep incline for fat burning, doing HIIT intervals, or training for hill runs, the machine’s incline capabilities can handle whatever you throw at it. While it doesn’t offer decline training, the 15 levels of incline combined with the unique manual mode provide plenty of variety for most users’ needs.
For serious runners and fitness enthusiasts who want commercial-grade incline features in their home gym, the ST90 delivers a premium experience that rivals that of high-end fitness facilities.
Why the Sole ST90’s AC Motor Makes It a Gym-Quality Powerhouse for Your Home
Ever wonder why some treadmills feel like they belong in a premium gym while others—well, not so much? The secret often lies in what’s under the hood. Today, let’s discuss why the Sole ST90’s AC motor turns heads in the fitness world.
At its core, the ST90 houses a 2.0 HP AC motor, but don’t let that number fool you. Manufacturers build AC motors differently, and here’s where things get interesting. Unlike typical home treadmills with DC motors, the ST90’s AC motor brings commercial-grade performance to your home gym.

First, it adjusts speed and incline faster than other Sole treadmills with DC motors. It is a game-changer if you’re into interval training or hate waiting for your treadmill to catch up with your workout plans.
But there’s more to it than just speed adjustments. AC motors excel in environments where durability and continuous operation are paramount. Think about it – this is the same type of motor you’d find in commercial gym equipment that runs daily.
The ST90’s motor easily handles everything you throw at it, powering speeds up to 12.5 miles per hour. Whether you’re walking, jogging, or sprinting, the motor maintains consistent performance without breaking a sweat. Plus, it comes with a 5-year warranty, showing Sole’s confidence in their motor’s longevity.
While AC motors tend to be a bit louder than their DC counterparts, they make up for it with superior durability and consistent performance. If you’re serious about your home workouts and want equipment that can withstand intense training sessions, the ST90’s AC motor won’t disappoint.
The Bottom Line
The Sole ST90’s AC motor isn’t just about raw power—it’s about bringing commercial-grade reliability into your home gym. While it might be overkill for casual walkers, it’s perfect for runners, serious athletes, or households where multiple people frequently use the treadmill.
Combining this robust motor with features like a stable steel Z frame and the innovative slat belt design, you get a treadmill built to last and engineered to perform. It’s an investment in your fitness journey designed to go the distance—literally and figuratively.

It makes it simple to navigate through your workout options or check your stats at a glance.

Sometimes, the small things make a big difference in your workout experience. The ST90’s console includes thoughtful additions like built-in cooling fans and convenient cup holders to keep you comfortable during long training sessions.
What makes the ST90’s console truly special is how it combines commercial-grade durability with user-friendly features.
