What the UREVO Foldi 3S treadmill is
The UREVO Foldi 3S treadmill combines three things that usually come separately: a treadmill with a motorized incline, a handrail with heart rate sensors, and a laptop desk that raises and lowers. Most walking pads, including UREVO's own SpaceWalk models, slide under a standing desk you already own. The Foldi 3S brings its own workstation instead, then folds the frame and desk down to 6.5 inches high for storage. The user manual lists it as model URTM037, and it is sold in the US by UREVO and by Walmart, Target, Dick's Sporting Goods and Academy.
This review is based on UREVO's product page, FAQ and user manual, plus retailer listings. We have not used the Foldi 3S ourselves, and we did not find an independent hands-on review from a publication we trust. For UREVO's full range, see our UREVO walking pad round-up.

We compared UREVO's product page, the URTM037 manual, and the Walmart and Target listings. Speed, incline and the 120 kg limit match between the product page and the manual. The motor rating, desk travel and warranty differ between sources; details are in "Where the numbers disagree" below.
Who it suits
The Foldi 3S suits someone who wants to walk while working but does not own a standing desk, or does not want to buy one. The built-in desk puts a laptop or tablet directly over the belt, and UREVO's FAQ says it is meant for typing, reading and video calls at low walking speeds.
It also suits people who want more than desk walking from the same machine. With a 9% incline and a 7.6 mph ceiling, it covers incline walking and light jogging after work, which a 4 mph walking pad cannot. UREVO's advice is to clear the desk, use the handrail and clip on the safety key before raising the speed or incline.
It is best for a home office where the machine can stay in one spot. Folding it to 6.5 inches high helps it slide under a bed or against a wall, but at 87.5 pounds it is not something to move every day.
What stands out
A built-in desk that adjusts
The desk is the reason to buy a Foldi 3S over a walking pad. UREVO says the workstation is extra large and moves up to 11.8 inches using two buttons, so different people in a household can set their own height. Walmart and Target list the range as 35.5 to 47.3 inches, which is consistent with 11.8 inches of travel. A tablet stand with an anti-slip surface is included. UREVO does not publish the desk surface dimensions or a load limit for the desk, so keep heavy monitors off it.
Incline and a 7.6 mph top speed
The Foldi 3S has a motorized 0 to 9% incline in nine levels, the same range UREVO uses on its SpaceWalk 3S and SpaceWalk 5L pads. UREVO's FAQ recommends incline for dedicated exercise rather than desk work, which is sensible: a raised deck plus typing is a lot to manage at once. The 0.6 to 7.6 mph range matches the Strol 2S Pro, so the Foldi 3S can handle a steady jog.
Heart rate handles and a console
The handrail has built-in heart rate sensors, and the console shows heart rate, speed, incline and workout data. Rear armrests give you something to hold when getting on and off, and UREVO says they also help when repositioning the machine. The UREVO app connects by Bluetooth for guided modes such as AI Rhythm Fit, HIIT, MIIT and LIIT programs, terrain simulation and workout tracking. Target lists four exercise modes: free training, goal workout, immersive running and challenge mode.
Quiet by the maker's figure
UREVO rates the Foldi 3S at 45 dB or less and lists a 5-layer belt with an 8-point shock absorption system, which UREVO says it rated for 150,000 high-speed impacts. We could not find an independent noise measurement, so treat 45 dB as a maker claim. Our guide to walking pad noise explains what affects real-world sound.
Pros
- Built-in height-adjustable desk, so no separate standing desk is needed
- 0 to 9% motorized incline
- 7.6 mph top speed for light jogging
- Heart rate sensors in the handrail
- Folds to 6.5 inches high
Cons
- 87.5 pounds is heavy for a folding treadmill
- Folding does not shorten it, so it still needs 51.6 inches of floor length
- 265-pound limit
- No published desk size or desk load limit
- No independent hands-on reviews found
Drawbacks
It is heavy. At 87.5 pounds, the Foldi 3S weighs about 13 pounds more than the Strol 2S Pro and about 31 pounds more than the SpaceWalk 3S. UREVO's own FAQ says it is better for stationary placement than for frequent moving.
Folding saves height, not length. Folded, it is still 51.6 by 25.6 inches. That is fine for under a bed with enough clearance, but it will not tuck into a closet the way a fold-in-half pad does. If a small folded footprint matters most, our best foldable walking pads list covers models that fold in half.
Desk height for tall users. Retailers list a top desk height of 47.3 inches. UREVO does not say where that height is measured from or publish a recommended user height, so tall walkers should compare that figure, plus the deck height, with their standing elbow height before buying.
A 265-pound limit. This is typical for UREVO's lighter models but well below the 400 pounds UREVO lists for the FoldiMix 5L and SpaceWalk 5L.
Limited outside coverage. We found no in-depth review from an established publication, so the case for the Foldi 3S rests mostly on UREVO's own figures.
Who should skip it
Who should skip it: anyone over 265 pounds (the FoldiMix 5L lists 400 pounds), anyone who already owns a standing desk and only needs a pad to put under it (the SpaceWalk 3S gives the same incline for much less weight), and anyone who needs to carry the machine up or down stairs.
Choosing a UREVO folding treadmill: where the Foldi 3S fits
UREVO uses the word folding for several different designs, so it helps to know which kind you are buying. The Foldi 3S folds its desk and frame down flat. The Strol models fold only the handrail. UREVO's SpaceWalk pads are flat to begin with.
| UREVO model | How it folds | Desk | Incline | Top speed | Weight limit | Product weight |
|---|---|---|---|---|---|---|
| Foldi 3S | Desk and frame fold to 6.5 in high | Built in, adjustable | 0 to 9% | 7.6 mph | 265 lb | 87.5 lb |
| FoldiMix 5L | Handrails fold | Built in, adjustable | 0 to 9% | 7.6 mph | 400 lb | 65.3 lb |
| Strol 2S Pro | Handrail folds to 6.69 in high | No | 0 to 9% | 7.6 mph | 265 lb | 74.51 lb |
| Strol 2E | Handrail folds to 4.6 in high | No | None | 6.2 mph | 265 lb | 47.2 lb |
All figures are from UREVO product pages, checked on 28 September 2026. If you already own a standing desk, the Strol models are lighter ways to get a handrail and jogging speeds. If you want the desk built in, the choice is between the Foldi 3S and the FoldiMix 5L.

Foldi Mini vs Foldi 3S
The Foldi Mini (model URTM006) is an older, simpler UREVO folding treadmill, and it is a very different machine from the Foldi 3S. It has no incline and no built-in desk. Retailer and UREVO listings describe a 2.25 HP motor, 0.6 to 6.2 mph, a 265-pound limit, a 16-inch-wide belt, 12 HIIT programs and an LCD screen that rotates. It weighs about 50 pounds and folds in one step to about 5 to 5.5 inches high.
| Spec | Foldi 3S | Foldi Mini |
|---|---|---|
| Motor | 2.5 HP | 2.25 HP |
| Speed | 0.6 to 7.6 mph | 0.6 to 6.2 mph |
| Incline | 0 to 9%, motorized | None listed |
| Desk | Built in, adjustable | No (phone holder) |
| Max user weight | 265 lb | 265 lb |
| Product weight | 87.5 lb | 49.8 to 50 lb (varies by listing) |
| Folded height | 6.5 in | 5.1 to 5.5 in (varies by listing) |
Availability. On 28 September 2026, UREVO's Foldi Mini product page redirected to the Foldi 3S, UREVO's refurbished Foldi Mini listing showed as sold out, Best Buy listed it as unavailable and Walmart's listing was out of stock. UREVO still hosts the URTM006 manual. Treat the Foldi Mini as a model you may find used or from leftover stock, not as a current UREVO product, and treat the Foldi 3S as its replacement in the Foldi name.
UREVO Foldi Mini treadmill reviews. We did not find an in-depth independent review of the Foldi Mini from an established publication. Owner reviews exist on retailer pages such as Best Buy, but we do not reproduce them here. The listings also disagree on key figures: Best Buy describes a 48-inch running surface and a 48 by 26 by 5.5-inch folded size, UREVO's refurbished page lists 48 by 22.8 by 5.1 inches, and Wellbots lists both 265 and 220 pounds as the maximum load. Warranty claims range from 2 years (Wellbots) to a lifetime guarantee in a Best Buy Q&A answer, which is not an official warranty document. If you find one new, confirm the warranty in writing with the seller.
How it compares
UREVO FoldiMix 5L
The FoldiMix 5L is the Foldi 3S's closest sibling: it also has a height-adjustable desk, 0 to 9% incline and 0.6 to 7.6 mph. UREVO lists a 3.0 HP dual brushless motor, a 400-pound limit and 65.3 pounds of weight, all better than the Foldi 3S on paper. The catch is its smaller 39.4 by 15.8-inch running area and a desk that UREVO says rises up to 9.06 inches, versus 11.8 inches on the Foldi 3S. Taller walkers with long strides may prefer the Foldi 3S; heavier walkers should look at the FoldiMix 5L.
UREVO Strol 2S Pro
The Strol 2S Pro has the same speed, incline and 265-pound limit, and a similar running area (42.52 by 16.54 inches), but no desk. It weighs 74.51 pounds. It is the better choice if you already have a standing desk. Our Strol 2S Pro review covers it in full.
UREVO SpaceWalk 3S
The SpaceWalk 3S walking pad matches the Foldi 3S on incline, weight limit and running area (42.5 by 16.54 inches), but it tops out at 4.0 mph, has no desk and no built-in handrail, and weighs 56.65 pounds. Pair it with a standing desk you already own for a lighter setup.
Where the numbers disagree
- Motor: UREVO's product page lists 2.5 HP at 3,800 RPM. Target calls it 2.5 HP continuous. A UREVO blog post comparing the SpaceWalk and Foldi series lists a 2.25 HP motor for the Foldi 3S. We use the product page figure.
- Desk travel: the product page says the desk adjusts up to 11.8 inches, and Walmart and Target list 35.5 to 47.3 inches, which agrees. The same UREVO blog post says the Foldi desk adjusts up to 22 cm (about 8.7 inches).
- Warranty: UREVO lists 1 year plus a 180-day extension. Target, where a third-party seller lists it, says 1-year limited warranty.
- App name: UREVO's page says UREVO app; Walmart and Target call it the UREVO SmartCoach app.
- Weight limit: UREVO lists 265 pounds (120 kg). The manual's error code notes also give 120 kg, which converts to about 264.5 pounds, so the figures agree.
- Amazon: we did not find a US Amazon listing named Foldi 3S in search results. Amazon Italy lists a Foldi 3S, and a US Amazon listing for a UREVO foldable treadmill with an adjustable laptop desk and 9% incline appears in search results, but its title describes a dual brushless motor that UREVO does not list for the Foldi 3S, so we have not linked it as this model.
Setup, maintenance and warranty
Setup. UREVO lists a hex tool, two bottles of lubricating oil, a power cord, a safety key and the user manual in the box. The manual's folding steps are simple: turn the fold lever counterclockwise to release it, lift the armrest up, then turn the lever clockwise to lock, and make sure the upright is locked before you walk.
Placement. The Foldi 3S weighs 87.5 pounds, so choose a spot where it can stay. A mat under it protects floors; see our treadmill mat picks.
Maintenance. The manual recommends 5 to 10 mL of lubricant roughly every 100 miles, and our guide on how to lubricate a walking pad covers the method. It also explains belt centering with the hex tool in quarter-turn steps, and lists error codes from E01 to E12, including E10 for a missing safety key and E04 for over-current protection.
Warranty and returns. UREVO lists a 1-year warranty plus a 180-day extension and a 14-day return window for unused products with all packaging. You pay return shipping if you change your mind; UREVO covers it for damaged or defective units. UREVO's product page also lists a 4-hour maximum continuous use, so plan breaks on long workdays.
Safety and recalls
No CPSC recall for UREVO walking pads or treadmills, including the Foldi 3S and Foldi Mini, was listed when we checked on 28 September 2026. You can check the current list at cpsc.gov/Recalls. The Foldi 3S uses a cord-type safety key: the manual says pulling it stops the belt and shows E10. Clip it on before you start, clear the desk before you raise the incline or speed, and keep children and pets away from the rear of the belt.
