The UREVO SpaceWalk 5L is a £349.99 walking pad that adds two things most budget pads skip: a motorised incline up to 9% and an app that changes your speed and gradient for you during guided sessions. Our UREVO SpaceWalk 5L review lands on a clear position. It's a quiet, comfortable machine for walking and hill-walking at home, but the 40cm-wide belt is narrow, the top speed is walking pace, and cheaper rivals already offer a steeper climb.
So who's it for? People who'll walk most days, want hills without stepping off to prop the deck up, and actually like the idea of app-led workouts. If that's you, it's a good buy. If you just want a flat pad under the desk, it's more money than you need to spend.
How we review
We haven't tested the SpaceWalk 5L in person. This review is built from UREVO's published specifications, the Amazon UK listing as of 27 October 2026, and the patterns that come up repeatedly in owner feedback on this and similar UREVO pads. Where sources disagree on a spec, we say so rather than picking the most flattering figure.
The SpaceWalk 5L is a low, flat walking pad with no upright console. It's about 124cm long, 51.5cm wide and 15.5cm tall, and weighs roughly 23kg, so it'll slide under most sofas and beds when you're done. The walking surface is 40x100cm, which is standard walking-pad size and noticeably smaller than a full treadmill.
Underneath sits what UREVO calls a 2.5HP "dual brushless motor". Brushless motors run quieter and shed less dust than the brushed motors in very cheap pads, and they generally need less maintenance. The headline horsepower figure is a marketing number, though, and is likely a peak rather than continuous rating. At walking speeds it's more than enough.
The cushioning is described as a 12-point system: eight silicone dampers, a floating deck and four support points. That's a sensible design for a machine you'll stand on for an hour at a time. Don't expect it to feel like a sprung gym treadmill; it's a firm, low deck with some give.
Check price on AmazonFlat walking pads are great for steps but limited as exercise. Once you're walking at a comfortable pace, the only way to work harder on a flat deck is to go faster, and on a pad that tops out around 6km/h you hit the ceiling quickly. Incline fixes that.
The research backs this up. In a study published in the Journal of Biomechanics, 16 people walked at their preferred speed on a treadmill at 0%, 5% and 10% gradients. Net metabolic cost rose sharply with incline: about 52% higher at 5% and roughly double at 10% compared with level walking, with the calf and quad muscles driving most of that increase. The SpaceWalk's 9% setting sits close to the top of that range. Walking uphill at 4 to 5km/h feels like real exercise, not a stroll, and it's gentler on your joints than running.
The incline is motorised, with nine levels. You change it mid-walk rather than stepping off to adjust a manual stand, which is the main practical advantage over the Toputure 12% incline walking pad. On the Toputure you pick 1%, 6% or 12% before you start and that's it. On the UREVO you can climb and descend through a session, and the app can do it for you.
One caution: some listings for this model mention 12%. UREVO's own spec figures say 9%. Buy it on the basis of 9%.
This is where UREVO is trying to justify the price. The app includes:
The useful part is the automatic control. A programme that raises the gradient for two minutes and drops it for one is far easier to follow when the machine does it than when you're reaching for buttons. If you've ever drifted back to a flat 3km/h after ten minutes, that structure helps.
The less useful part is that it's another app. Owner feedback on app-led walking pads in general follows a familiar pattern: people who use the programmes love them, while people who just want to walk while working find app pairing and account sign-ups a chore. UREVO's warranty extension has also been reported to need app registration, which is worth knowing if you'd rather keep the machine offline.
Be sceptical of the listing's claim that incline and HIIT raise calorie burn "by 190%". That figure has no source attached. The real gain from walking uphill is substantial, as the study above shows, but it depends on your speed, gradient and body weight.
Here's the honest limit. UREVO lists a speed range of 0.6 to 4mph, which works out at roughly 1 to 6km/h. That's a walking range. Most adults walk briskly at 5 to 6km/h and start jogging somewhere above 7km/h, so this machine won't let you run, full stop. Our guide on whether you can run on a walking pad explains why short, narrow decks and low top speeds go together.
The 40cm width matters more than people expect. A full treadmill belt is usually 45 to 50cm wide. At 40cm, if you're looking at a monitor, taking a call or just walking with a slightly wide gait, your feet can drift towards the edge. Taller walkers and anyone with a broad stance will notice it most. There's no handrail either, so when the deck is tilted to 9% you've got nothing to hold. Walk centred, keep the speed sensible on steep settings, and you'll be fine. If balance is a concern, a model with a rail is the safer pick.
The 100cm length is enough for a normal walking stride. It's the width, not the length, that's the compromise here.
| Price (Amazon UK, 27 Oct 2026) | £349.99 |
|---|---|
| Motor | Dual brushless, advertised as 2.5HP |
| Speed range | 0.6 to 4mph (approx 1 to 6km/h), per UREVO |
| Incline | Motorised, 9 levels, up to 9% |
| Walking area | 40 x 100cm |
| Max user weight | 136kg (Amazon UK listing) |
| Dimensions | Approx 124 x 51.5 x 15.5cm |

The Amazon UK listing gives a 136kg capacity. That's a decent figure for a walking pad, and it matches what UREVO quotes for its pricier 4-in-1 model. The awkward bit is that different UREVO sources list different load ratings for the 5L, and the same goes for noise and machine weight. This isn't unusual with walking pads sold in several countries under slightly different specs, but it does mean you shouldn't plan to run the motor at its limit. Our explainer on walking pad weight limits covers why staying well below the rated figure helps motors and belts last, especially on an incline.
If you're over about 120kg, the MERACH 12% incline walking pad lists a much higher user limit and a slightly wider 42cm belt, and it's worth a look first.
Three machines on our site make useful reference points:
| Model | Price | Incline | Top speed | Belt | Handrail |
|---|---|---|---|---|---|
| UREVO SpaceWalk 5L | £349.99 | 9%, motorised | Approx 6km/h | 40 x 100cm | No |
| MERACH 12% incline walking pad | Around £240 | 12%, motorised | 6km/h | 42cm wide | No |
| Toputure 12% incline walking pad | Around £240 | 1/6/12%, manual | 12km/h | 40 x 100cm | Yes |
| UREVO 4-in-1 desk treadmill | Around £600 | 9%, motorised | Walking and light jogging | 40 x 100cm | Yes, plus desk |
The MERACH is the awkward comparison for UREVO. It's cheaper, climbs to 12% with a motorised incline, has a wider belt and a higher load rating, and shares the walking-only top speed. What it lacks is UREVO's app content. If you don't care about World Tour or HIIT sessions, the MERACH is the better value.
The Toputure is the cheap route to a steep climb plus a handrail, at the cost of manual incline. The UREVO 4-in-1 desk treadmill shares the 9% motorised incline and 136kg rating, adds a desk and handrail, and costs far more. If you already own a standing desk, the SpaceWalk 5L gets you most of what matters for £250 less.
A 30-minute brisk walk on most days gets you to the NHS target of 150 minutes of moderate activity a week without much planning. Brisk walking counts. Add incline and that same half hour does more work.

No. UREVO's own spec sheet lists a speed range of 0.6 to 4mph, which tops out around 6km/h. That's a brisk walk for most adults. The 100cm deck is also too short for a running stride, so treat this as a walking machine only.
It has nine motorised incline levels up to 9%, and the deck tilts while you're walking. Some listings mention 12%, but UREVO's own figures say 9%, so buy it expecting 9%.
The Amazon UK listing says 136kg. Different UREVO sources quote different load figures for this model, so if you're near that number, leave yourself a margin rather than running the machine at its limit.
The brushless motor is the quiet part. Footfall is the louder part on any walking pad, so a rubber mat underneath helps a lot if you've got neighbours below. At walking speeds it's well suited to use under a desk or in a shared living room.
The app is where the World Tour routes, RhythmFit music sessions and HIIT programmes live, and it handles the automatic speed and incline changes during those sessions. If you only want to walk at a steady pace, the app matters less, but you'd be paying for features you won't use.
