The MERACH Performance folding treadmill is a value play, and a fairly bold one. It packs a spec sheet that reads like a machine costing several hundred pounds more: a 3.5HP brushless motor, a proper 18 percent automatic incline, and a gym-style shock-absorbing belt, all in a folding frame priced around £595. Brushless motors and auto incline usually live on treadmills wearing NordicTrack or Sole badges, so seeing them at this price from MERACH is the whole reason this machine is interesting. The verdict up front: it's a lot of treadmill for the money, and the main question mark is long-term reliability from a brand without the decades of history the premium names carry.
MERACH has built a solid Amazon following with rowers and bikes, and this treadmill extends that budget-to-mid-range formula: give people the features that matter, keep the price sharp, and accept a warranty and a track record that can't yet match the established players. Whether that trade works for you depends on how much you value the incline and motor versus the reassurance of a proven long-term name.
How we review
This review is based on MERACH's published specifications, verified owner feedback and how the machine compares with treadmills in the same price bracket. We have not run a multi-year reliability test of this exact unit, so we have focused on the spec, the value case and the consistent themes in owner reviews, both positive and negative, rather than one-off opinions.
This treadmill makes the most sense for home runners and walkers who want incline training on a budget and have space to fold a machine away. If you want to do hill sessions, walk at a steep gradient for fat loss, or run steady miles indoors without spending over a grand, the spec is genuinely appealing. The auto incline in particular is a feature most treadmills near this price simply don't have. Regular running carries a striking health return: even modest amounts are linked to meaningfully lower mortality risk (leisure-time running and mortality study), and a home machine removes most of the excuses.
It's less suited to high-mileage marathon runners who'll hammer it daily for years, and to anyone who specifically wants the peace of mind of a long, proven reliability record, where a premium brand still wins.
The brushless motor is the standout, and it's not just marketing. Brushless motors run cooler and quieter than the brushed motors on most cheap treadmills, and they tend to need less maintenance over time, so a 3.5HP brushless unit is a real step up from the noisy motors you find at the bottom of the market. For a home where someone's asleep upstairs or you're on a call nearby, that quieter run matters more than the numbers suggest.
The 18 percent auto incline is the feature that separates this from its budget rivals. Manual incline, where you stop and physically prop up the deck, is a chore that people stop using. Automatic incline changes the gradient mid-session at the touch of a button or under app control, which turns hill intervals and steep walking workouts from a hassle into something you'll actually do. Combined with the shock-absorbing 46cm by 140cm belt, it's a setup that genuinely supports varied training rather than just flat plodding. The belt width is comfortable for most, though I'd flag that tall runners with a long stride, or anyone used to a commercial deck, will notice it's narrower than the 51cm-plus belts on premium machines.

Where this treadmill earns its keep is variety. Flat treadmills get boring and stop challenging you quickly; the auto incline here means you can run rolling-hill profiles, do steep-walk fat-loss sessions, or program intervals that ramp the gradient without breaking stride. That's the kind of training that keeps you coming back, and it's the single biggest reason to pick this over a cheaper flat machine or a walking pad.
The app connectivity adds guided and interactive sessions, which some owners love for structure and motivation. It's a smaller, less polished ecosystem than the iFIT platform you get on a NordicTrack, so set expectations there, but as a way to follow along with a coached run or track progress, it does the job. However you use it, a home treadmill makes it far easier to hit the NHS target of regular aerobic activity across the week (physical activity guidelines), and the incline lets you build intensity without pounding out huge distances.

Here's the honest heart of it. On spec and price, the MERACH is excellent value, offering motor and incline features that usually cost more. What you're trading for that price is track record. NordicTrack and Sole have decades of treadmills in the field and the reputation, warranty and parts support that come with it. MERACH is newer to treadmills, so you're betting on kit that hasn't yet been proven over ten years of daily home use, and the warranty typically reflects that with shorter cover.
For a lot of home users, that's a reasonable bet. If you run a few times a week and look after the machine, the odds are good, and the money you save is significant. If this treadmill will be the hub of daily high-mileage training for years, or you simply want the reassurance of a long proven history, spending more on a premium brand buys you that certainty. Our best incline treadmill UK guide and best treadmill under £1000 round-up put this machine in context against those alternatives.
Check price on AmazonAgainst premium folding treadmills, the MERACH gives up belt width, warranty length and brand reliability, but it undercuts them heavily on price while keeping the two features that matter most, a strong motor and real auto incline. Against cheaper machines, it wins comfortably on motor quality, belt size and that automatic gradient. It sits in a sweet spot for value-focused buyers. If you want to see how the established names stack up, our NordicTrack T Series review and the wider treadmills hub are the places to look next.
For the money, it punches above its weight. You get a 3.5HP brushless motor, a genuine 18 percent auto incline and a folding frame for well under £600, a spec that usually costs more from the big-name brands. The trade-off is that MERACH does not have the decades-long reliability record of a NordicTrack or Sole, so you are betting on newer kit. For most home runners and walkers who want incline training without the premium price, it is a strong value pick.
Yes. It offers auto incline up to 18 percent, which is a real feature at this price and rare on budget folding treadmills. Automatic incline lets programmes and apps adjust the gradient for you mid-workout, which makes intervals and hill sessions far more effective than a flat belt.
The running belt is around 46cm wide by 140cm long, described as gym-style with shock absorption. That is a comfortable width for walking and steady running for most people, though very tall runners or those with a long stride may prefer the wider 51cm to 56cm belts on premium machines.
Yes, it folds for storage, which is the main reason to choose it over a fixed-frame machine if space is tight. As with any folding treadmill, the folding mechanism and hydraulics are a wear point over years of use, so raise and lower it gently rather than letting the deck drop.
Both. The 3.5HP brushless motor and the belt size handle running as well as walking, unlike walking-pad style machines that top out around 6 to 10 km/h. It suits home runners doing steady miles and interval work, though serious high-mileage runners training for marathons may eventually want a heavier-duty gym machine.
