If you've shopped the big box stores and poked around online, you may have found a vast array of treadmills that all look alike. That's because Costway, the parent company for GoPlus also sells treadmills under the names Gymax, Slickblue, and Tangkula.
The Goplus SuperFit swaps high-end performance for a clever 2-in-1 footprint, making it clear that convenience is the priority here over a gym-quality workout. While full-sized machines offer sprawling decks and high-speed capability, this model is effectively restricted to walking or low-impact jogging due to its smaller tread surface and capped speed range (which drops to 2.5 mph when the handrails are folded). Though it remains a straightforward, utilitarian solution for adding steps to your workday, modern versions have moved away from being “bare-bones” and now often include Bluetooth speakers and app connectivity via the Gymax or FitShow platforms. It isn't a machine for marathon training, but it is a reliable, space-saving tool for those who want to keep moving without a complex, bulky setup.
The Goplus SuperFit operates with two specific speed profiles: a 2.5 mph walking mode optimized for under-desk use and a 7.5 mph running mode for standalone workouts. While its maximum speed is humble compared to gym-grade machines, it aligns perfectly with the compact 40" x 16" deck, which is better suited for a steady pace than an all-out sprint. Because the surface is both narrow and short, you'll need to maintain a disciplined stride to stay centered, making it a stellar option for casual walking or light cardio. However, taller individuals or those with naturally longer gaits may find the platform's footprint a bit too cramped for an unrestricted run.
Every workout on the Goplus SuperFit is manually controlled. There are no programmed workouts, and the user is responsible for adjusting the tread speed and keeping track of time, distance, or calories burned. Again, this model is very basic, especially when compared to fancy high-end models with connected features and touchscreens.
The Goplus SuperFit simplifies your workout by using Bluetooth purely for its integrated speakers, allowing you to enjoy music or podcasts without the hassle of headphones. While the original hardware was famously “unconnected,” it's worth noting that the 2026 models have stepped up their tech game; they now feature Gymax app integration, which lets you track your workout history and control the treadmill's speed directly from your smartphone. However, it still lacks compatibility with high-end third-party training platforms like Zwift or Peloton, keeping it firmly in the category of a straightforward, distraction-free walking tool rather than a fully immersive fitness hub.
While the Goplus SuperFit excels at simple, “plug-and-play” operation, it struggles with long-term ergonomic comfort. While launching a workout is as easy as flipping a switch, you are forced to rely entirely on a small, handheld remote to adjust your pace, which can feel clumsy during more active sessions. Furthermore, the minimalist LED display is tucked away at the base of the machine, making it difficult to monitor your progress as it slowly cycles through individual metrics such as speed, time, and distance. While recent 2026 iterations have introduced Gymax app connectivity to allow for smartphone-based controls, the physical interface remains a bare-bones compromise that trades high-tech functionality for a lower price and a sleeker footprint.
Starting a workout on the Goplus SuperFit is refreshingly immediate, requiring only a flip of the base power switch and a press of the handheld remote to get the belt moving. Since the machine lacks complex programmed workouts or immersive software, you can focus entirely on your pace without having to navigate menus. While it's a “plug-and-play” favorite, remember that the magnetic safety key must be securely in place for the console to activate. Furthermore, if you're transitioning from under-desk storage to a more intense session, you'll need to lock the handrail into the upright position to unlock “Run” mode and its higher-speed capabilities.
The Goplus SuperFit keeps its feedback loop simple with a base-mounted LED display that cycles through your essentials: elapsed time, distance, calories, and speed. While the digits are bright and clear, their low-slung position at the very front of the belt means you'll be glancing down frequently, which can be a bit awkward during a steady stride.
Note on Metrics: Be aware that many versions of this machine default to km/h rather than mph, which might require some quick mental math if you're used to tracking your pace in miles.
Control is handled entirely through a compact handheld remote. Since there are no buttons on the handrail, this remote is your only way to adjust the intensity of your workout. While this “minimalist” approach is effective for a walking pad, clutching a plastic clicker for the duration of a jog can feel a bit like running through your living room while holding a TV remote, functional, but occasionally a bit of a nuisance.
The Goplus SuperFit is a textbook “no-frills” machine, purposefully dodging high-end clutter to focus on what matters most for small-space living: extreme portability. While it lacks the massive consoles or automatic inclines found on commercial rigs, its feature set is cleverly curated to maximize convenience.
The Goplus SuperFit features a clever folding handrail that toggles between a low-profile walking mode and a more traditional running setup. This single design choice allows the treadmill to shrink down to a remarkably slim 5-inch profile, making it a “disappearing act” for anyone living in an apartment where every square foot counts.
Beyond its hideaway capabilities, the machine remains surprisingly functional for its size, offering built-in transport wheels for effortless moving and a convenient smartphone bracket paired with Bluetooth speakers. It's a straightforward, utilitarian approach to fitness that proves you don't need a massive footprint to maintain a consistent movement habit.
The Goplus SuperFit excels in setup, arriving nearly fully assembled and requiring only a few simple steps to get moving. Its compact, lightweight frame makes unboxing and maneuvering far easier than bulkier competitors, ensuring a stress-free start for any user.
At roughly 80 pounds boxed, the Goplus SuperFit is relatively light for a treadmill, though unboxing is still a two-person job. Assembly is a quick 20–25-minute process that involves attaching the phone bracket and side handles. However, a notable design quirk remains: the handles are bolted on, so you must remove them manually each time you want to fold the rail into “walk” mode, or leave them off for a more seamless transition between modes.
The Goplus SuperFit stands out for its exceptional storability, with a remarkably slim 5-inch profile that makes it an excellent choice for tight spaces. While its compact dimensions and modest speeds are better suited to walking than to high-performance training, its ability to virtually disappear under a bed or sofa offers a level of convenience that bulkier competitors simply can't match.
Even in “Run” mode with the handrail raised, the Goplus SuperFit maintains an impressively small footprint of 51" L x 27" W and a height of 41.5", making it one of the most compact units in our 2026 testing lineup. When the handrail collapses, it can vanish under a bed, sofa, or inside a shallow closet. At only 70 pounds with clever transport wheels, you can simply roll it away.
The GoPlus is a relatively quiet treadmill, comparable to the other models I tested. Like most treadmills, the majority of the noise comes from your footfalls when walking or jogging on it.
The Goplus SuperFit isn't built for marathon training, but it has a downright functional design. Its folding handrail allows it to pivot instantly from a standalone power-walker to a discreet under-desk companion for active workdays. By prioritizing a slim profile that easily vanishes under a sofa or bed, it offers a seamless way to boost your daily step count without permanently sacrificing your living room to bulky gym equipment.
