The UMAY walking pad line-up at a glance
UMAY is an Amazon-first fitness brand that sells in the US through two storefronts: Umay Fitness (umayfitness.com), which lists the incline pads and a set of folding treadmills, and a second store called umay_us (umaystore.com), which carries the long-running UMAY 512. Amazon lists both under the UMAY and UMAY Fitness names. Umay Fitness gives a US phone line and email support, Monday to Friday, 9am to 5pm Pacific time, and says orders ship from local warehouses.
This review covers the four UMAY walking pads we could match to a named model on a maker page or a major retailer listing: the 512, the U17, the U20F and the X5F. They differ more than the shared branding suggests. The 512 is a flat pad with a long belt and no incline. The U17 adds incline without a handle. The U20F and X5F are fold-in-half 3-in-1 machines with handlebars and jogging speeds.

Who it suits
The UMAY walking pad family suits three kinds of buyer. If you want the simplest desk setup with a roomy belt and an app, the 512 is the one to look at. If you want to walk uphill at a desk and do not need a handle, the U17 is the only UMAY incline model with a published weight, a light 37.5 pounds. If you want to jog between calls, or you like something to hold, the U20F and X5F are the relevant models, with the U20F carrying the highest listed capacity of the four.
UMAY is a weaker fit if you want detailed manuals, published belt sizes for every model, or a single consistent spec sheet. Brands such as UREVO and Merach publish more complete figures; see our best walking pad with incline guide for those.
The UMAY models in detail
UMAY 512: the flat pad with the SPAX app
The 512 is the UMAY walking pad most shoppers meet first, because it has been on Amazon the longest. It is a flat pad with no incline and no handle, sold as a quiet under-desk walker with a remote and the SPAX app for classes and tracking. Its selling point is belt size: listings give the belt as 45.7 by 16.5 inches, with a usable walking area of 41.3 by 16.2 inches. That walking area is longer than many flat pads in the same price tier.
Key specs:
- Motor: 2.5 HP brushless (listing figure)
- Speed: 0 to 4 mph
- Walking area: 41.3 x 16.2 in (belt listed as 45.7 x 16.5 in)
- Weight: 55 lb (Woot listing)
- Size: 53.7 x 24 x 5.9 in
- App: SPAX; remote included
Who it suits: walkers who want a long, flat deck under a standing desk and like tracking sessions in an app.
Pros
- Longer walking area than most budget flat pads
- SPAX app support
- No assembly needed according to the listing title
Cons
- The weight limit differs between listing title and listing text
- At 55 pounds it is heavier to move than the U17
- No incline
Who should skip it: anyone near 265 pounds, until UMAY confirms which limit applies, and anyone who wants incline.
Where the numbers disagree: the Amazon listing title says 300 lb capacity, while the product text carried on Amazon's Woot store says 265 lb. An older UMAY under-desk base previewed by the Office Fitness Ninjas at WorkWhileWalking.com lists a 1.5 HP motor, a 198 lb limit, a 41 x 16 inch belt and 66.14 lb, which suggests earlier versions sold under similar names had different hardware. Amazon also carries a separate "512N" listing that mentions a "P1" name in its title. Match the exact listing to its spec sheet before you order.
UMAY U17: incline without a handle
The U17 is Umay Fitness's compact incline pad. The maker page offers it in a 9% version and a 15% version, rates it at 350 pounds, and gives a 2.5 HP brushless motor with a claimed life of more than 3,500 hours. At a listed 17 kg (37.5 lb) and 4.3 inches tall, it is the lightest UMAY incline pad we found. Umay Fitness describes triple cushioning: a 2-layer running plate, a 7-layer belt, 4 honeycomb rubber pads and 8 silicone dampers.
Key specs:
- Motor: 2.5 HP (1,865 W) brushless (maker figure)
- Speed: 1 to 8 km/h, listed as max 5 mph
- Incline: 9% or 15%, depending on version
- Max user weight: 350 lb
- Weight: 37.5 lb
- Size: 44.9 x 21.6 x 4.3 in
- Noise: under 45 dB (maker claim)
Who it suits: desk walkers who want incline in a light pad and do not need a rail to hold.
Pros
- Incline and a 350 lb rating in a pad under 40 pounds
- Low 4.3 inch profile
- Built-in wheels
Cons
- Belt size is not published
- The page does not say whether incline is motorized
- No handle
Who should skip it: tall walkers who need a known belt length, and anyone who wants to adjust the angle from a remote without confirming the version first.
Where the numbers disagree: the U17 page lists a 1-year parts and 5-year frame warranty but also mentions "2 Years Warranty" and a 730-day return or replacement service. The page groups the U17 with the U19 and U18F, and Umay Fitness's EU store sells a near-identical "U18" with the same 9% and 15% options, so the model name printed on the box may differ from the listing.
UMAY U20F: folding 3-in-1 with a foot-pad incline boost
The U20F is a fold-in-half pad with a handlebar, which Umay Fitness calls 3-in-1 because it covers desk walking, brisk walking and light jogging. The incline works differently from most walking pads: the base setting is a fixed 10% manual incline, and you reach 15% by adding the red foot pad included in the box. Umay Fitness lists 0.6 to 6.5 mph and a 400 lb capacity, the highest of the four models here, and a folded height of 4.3 inches. A Pro version adds armrests.
Key specs:
- Motor: 2.5 HP brushless (maker figure)
- Speed: 0.6 to 6.5 mph
- Incline: 10% manual; 15% with the included foot pad
- Max user weight: 400 lb (US page)
- Folded height: 4.3 in
- Belt: 6-layer non-slip, size not published
Who it suits: people who want a handlebar and occasional jogging, and heavier walkers who want the most headroom UMAY lists.
Pros
- Highest listed capacity in the UMAY walking pad range
- Handlebar for balance
- Folds for storage
Cons
- Incline changes by hand, not from the remote
- Belt size and product weight are not published
- Model naming is inconsistent
Who should skip it: anyone who wants to switch between flat and uphill during a work call, because the incline is set by hand.
Where the numbers disagree: the US page is titled U20F while its images and text refer to U18F. The US page says 400 lb and 6.5 mph; the EU version of the same page says 160 kg (about 353 lb) and 1 to 10 km/h (about 6.2 mph). The EU page also lists the same 17 kg weight and 114 x 55 x 11 cm size as the U17, which may be a copied figure.
UMAY X5F: 16% incline and a 3.0 HP rating
The X5F is the steepest UMAY walking pad in the walking pad collection, with a 0 to 16% manual incline set in 3 levels. It also carries the highest motor rating of the four at 3.0 HP. Folding side armrests give you something to hold, and the whole unit folds to 43.5 by 22.9 by 4.4 inches. It is the only one of the four with a published belt size among the incline models: 38 by 15.8 inches.
Key specs:
- Motor: 3.0 HP (maker figure)
- Speed: 1 to 6.5 mph
- Incline: 0 to 16%, manual, 3 levels
- Max user weight: 350 lb
- Belt: 38 x 15.8 in
- Folded size: 43.5 x 22.9 x 4.4 in
- Remote: wireless, with magnetic storage
Who it suits: short-stride walkers who want steep uphill work and a rail to hold, in a machine that folds away.
Pros
- Steepest incline of the UMAY pads
- Published belt size
- Fold-down armrests
Cons
- A 38 inch belt is short for jogging and for tall walkers
- Incline changes by hand in steps
- No app listed
Who should skip it: anyone over about 6 feet, who is likely to find a 38 inch belt cramped (see our walking pads for tall people guide).
Where the numbers disagree: the title says max 6.5 mph but the page metadata says 10 km/h, which is about 6.2 mph. The EU page's web address says 15% incline while its title says 16%. A Walmart listing for a UMAY "16% incline" pad gives 2.5 HP and a 330 lb limit, figures that do not match the X5F page, so treat third-party listings without a model number with care.
Other UMAY models you will see
Umay Fitness also sells the CW1F (a folding pad with a 9% incline, 7.5 mph top speed and a lower 265 lb limit), the C30 flat pad, the S5 with a full-screen display and the U19 vibration pad. Its SF10, SF20, L10, L20, U50, U70, U80 and X5FD are full treadmills rather than walking pads. The CW1F page lists a 1-year frame warranty rather than the 5 years shown on most UMAY pages, and one UMAY page lists the CW1F incline as motorized while the CW1F's own page says manual. We left these models out of the main comparison because their pages give fewer figures.
What stands out
- High listed capacities. Three of the four models list 350 lb or more, which is above the 265 lb common in this price tier.
- Incline across most of the range. Only the 512 is flat. The X5F's 16% is steeper than the 9% motorized incline on the UREVO SpaceWalk 3S.
- A frame warranty on paper. Most Umay Fitness walking pad pages list 5 years on the frame, which is longer than many Amazon-first brands state.
- A long flat option. The 512's 41.3 inch walking area suits desk walkers who do not want incline.
Drawbacks
- Inconsistent spec sheets. Model names (U18F and U20F), weight limits (265 or 300 lb on the 512; 400 lb or 160 kg on the U20F) and speeds shift between pages.
- Missing belt sizes. Neither the U17 nor the U20F page publishes belt length and width.
- Manual incline on the handle models. The U20F and X5F change angle by hand, so you stop walking to adjust.
- Thin independent coverage. We found no lab review from a major outlet for any current UMAY walking pad.
Who should skip it
Skip UMAY if you want an app-controlled motorized incline with a clearly published spec sheet, because the UREVO SpaceWalk 3S and Merach W50 document theirs more fully. Skip it if you are over 6 feet and want a known belt length on an incline model. And skip the 512 specifically if you are close to its lower 265 lb figure.
How it compares
UMAY U17 vs UREVO SpaceWalk 3S: the SpaceWalk 3S has a motorized 0 to 9% incline, a published 42.5 by 16.54 inch belt, a 265 lb limit and an app. The U17 lists a steeper 15% option and a higher 350 lb rating, but no belt size and no clear statement on whether the incline is motorized. Choose UREVO for known dimensions and remote-controlled incline; choose the U17 for the higher listed capacity in a lighter pad.
UMAY U20F and X5F vs Merach T19: the Merach T19, covered in our Merach walking pad review, is also a folding pad with a handlebar and manual incline. It lists 6% incline, a 37.4 by 16 inch belt, a 300 lb limit and up to 7.6 mph, and it works with the Merach app. The X5F goes steeper at 16% and the U20F lists 400 lb, but the T19 has a named app and a published belt on a model that shares the same fold-flat idea.
UMAY 512 vs DeerRun Z10: the DeerRun Z10 adds a motorized 0 to 12% incline and a 300 lb limit, but its belt is 34.84 by 15.75 inches. The 512's flat 41.3 inch walking area gives a longer stride. Pick the Z10 for incline, the 512 for deck length.
Setup, maintenance and warranty
Umay Fitness says its walking pads ship from US warehouses within 2 to 3 business days and arrive in 3 to 7. The U17 page says no assembly is needed, and the 512 listings describe it as installation-free. The folding U20F and X5F need the handle raised and locked before use; follow the manual for the locking steps.
For upkeep, keep the belt centered and lubricated on the schedule in the manual; our walking pad lubrication guide covers the method. Umay Fitness sells replacement remotes, and third-party remotes on Amazon list compatibility with UMAY C30, C40, X5, X5F, P1 and P2 models.
Warranty terms vary by page. The Umay Fitness homepage lists a 1-year warranty and 30-day free returns. Most walking pad pages list 1 year on parts and 5 years on the structural frame. The CW1F page lists 1 year for both, and the U17 page also mentions 2 years. The 512 is sold through a different storefront and we did not find its warranty terms published. Ask the seller to confirm in writing which terms apply to your order.
