The merach w50 under desk treadmill walking pad is designed for people who want more than a basic flat walking surface. The MERACH NovaWalk W50 TrekPad combines a 12% automatic incline, a 16.5-inch-wide walking belt, a 400-pound manufacturer-rated weight capacity, and a brushless motor with 1.25 HP continuous and 3.5 HP peak power. Its biggest advantages are its adjustable incline and spacious walking area, while its main compromises are a relatively heavy 69.2-pound frame, a non-folding design, and a maximum speed of just 4 mph. It is particularly interesting for home-office users who want incline walking without buying a full-sized running treadmill.
Quick verdict on the MERACH W50 under desk treadmill walking pad
The MERACH NovaWalk W50 TrekPad is a strong option for buyers who prioritize walking comfort, automatic incline, and a higher advertised weight capacity.
Its 16.5 x 41.3-inch walking belt is more spacious than the narrow decks found on many entry-level walking pads. The 12% motorized incline also makes it more versatile than a flat under-desk treadmill, allowing users to increase workout difficulty without relying entirely on speed.
Another advantage is its stated 400-pound maximum user capacity. This makes it worth considering for heavier users who find the weight limits of many compact walking pads restrictive.
However, the W50 is not ideal for everyone.
It weighs approximately 69.2 pounds, does not fold in half, and reaches a maximum speed of only 4 mph. Although it has transport wheels and can be stored vertically, moving it still requires some effort.
Its 6.1-inch height also makes desk compatibility important. A desk that accommodates a thinner walking pad may not provide enough clearance or comfortable typing height with the W50 underneath.
Overall verdict: The W50 is worth considering for buyers who want a wide walking surface, automatic incline, and a high manufacturer-rated weight capacity. It is less suitable for people who need foldable storage, regular running speeds, or a particularly lightweight machine.
Product overview and exact model identification
What the MERACH W50 under desk treadmill walking pad actually is
The MERACH W50 is marketed under the NovaWalk W50 TrekPad name.
Its US production model number is MR-T25B2-US. MERACH explains in its official product FAQ that some packaging may display T25 because that is the production model designation, while W50 is the sales name.
This distinction matters because MERACH sells several walking pads and treadmills with similar model names.
The product reviewed here is the US W50 with a 12% automatic incline, not the W50 Lite or the European MR-T25 variant.
The W50 is a non-folding walking pad. Instead of folding its deck in half, it uses transport wheels and a vertical-storage design to help users move it out of the way.
Its main features include:
-
A brushless DC motor.
-
Automatic incline adjustment up to 12%.
-
A 400-pound advertised maximum user capacity.
-
A magnetic remote control.
-
An LED workout display.
-
MERACH app compatibility.
-
A reinforced deck and cushioned walking belt.
The product arrives assembled according to the manufacturer’s documentation. Users need to unpack it, place it on a suitable surface, connect the power cord, and prepare the remote.
This makes initial setup simpler than assembling a conventional treadmill with an upright console.

Some technical details require qualification.
The motor’s 3.5 HP figure is peak horsepower. The manufacturer separately identifies 1.25 HP as continuous horsepower. These are different measurements and should not be treated as interchangeable.
The belt measurement also varies between sources. MERACH currently publishes 16.5 x 41.3 inches, while a Manuals.plus-hosted copy of the W50 manual lists 16.5 x 42.5 inches. Consumer Reports lists a 40.25-inch belt length for the W50. These differences should be resolved against the actual production specification before using the length as a definitive comparison figure.
The manufacturer’s published 400-pound capacity is also a rated limit, not an independently established load-test result.
Design, construction, and storage
The W50 has a substantially different storage approach from traditional folding walking pads.
Its frame does not fold in half. Instead, the product uses a rigid structure that MERACH describes as an anti-fold design.
The benefit is a more substantial treadmill-style platform without a central folding joint. That may appeal to buyers who prefer a fixed walking deck.
The disadvantage is that it cannot be reduced to a compact folded package.
Its overall dimensions are approximately 50.2 x 22.2 x 6.1 inches. This is manageable for a dedicated home exercise area, but it still occupies meaningful floor space.
The machine has transport wheels to help reposition it. MERACH also markets vertical storage as a space-saving feature.
However, vertical storage does not make the treadmill lightweight. At 69.2 pounds, moving it upright requires more effort than moving a 40- or 50-pound walking pad.
For apartment dwellers, this is particularly important. A machine that can be rolled away is convenient, but buyers should still measure doorways, storage areas, and the available floor space.
The 6.1-inch deck height is another practical consideration. If the treadmill will be placed beneath a standing desk, users should check whether their desk can accommodate the additional height without forcing an uncomfortable working posture.
Walking belt size and comfort
The W50’s 16.5-inch belt width is one of its strongest specifications.
Many smaller walking pads use narrower belts that require users to pay closer attention to foot placement. A wider surface offers more lateral room during ordinary walking.
Its published belt length of 41.3 inches is also reasonably generous for this category.
Fortune’s testing team evaluated the NovaWalk W50 and reported that a tester taller than 6 feet found the walking surface sufficiently spacious for a natural stride.
That is a useful model-specific observation, although individual stride length and walking habits still matter.
The manufacturer also advertises a reinforced deck and six-layer cushioned belt.
These are intended to provide a stable and more comfortable walking surface. However, MERACH does not provide independently verified impact-reduction measurements for the W50. The cushioning description should not be interpreted as proof of a specific joint-protection benefit.
Automatic incline and practical workout options
The W50’s 12% automatic incline is its main feature advantage.
Unlike walking pads that rely on manually adjusting the frame or adding external supports, the W50 allows the incline to be adjusted through its control system.
Users can operate incline settings using the magnetic remote or MERACH app.
An incline changes the physical demands of walking. Moving uphill generally requires more effort than walking at the same speed on a flat surface.
This gives the W50 more workout variation than a basic flat walking pad.
It is particularly useful for people who prefer slower walking speeds but still want to vary the difficulty of their sessions.
However, there is a small documentation discrepancy.
MERACH’s headline product description advertises a maximum 12% incline, while its detailed specification lists a 1–12% range. Other marketing copy refers to a 0–12% range.
The maximum is consistently advertised as 12%, but the exact minimum incline setting should be confirmed with the seller if a completely flat starting position is important.
Another consideration is desk ergonomics.
At a higher incline, the user’s effective standing position changes relative to the desk. A desk height that works comfortably on a flat surface may not work equally well when walking uphill.
For this reason, incline walking is likely more convenient for dedicated exercise periods, while flat walking may be more comfortable during typing or computer work.
The W50 is designed for walking, with a 4 mph speed ceiling. Its incline system adds workout variety, but it does not turn the product into a conventional running treadmill.
Motor performance and noise
The W50 uses a manufacturer-advertised brushless motor rated at 3.5 HP peak and 1.25 HP continuous.
The continuous rating is more useful than the peak figure when evaluating motor output for sustained exercise.
MERACH also advertises operation for up to 10 continuous hours. This is a manufacturer claim, not an independently verified guarantee that every user can safely operate the machine at maximum speed, maximum incline, and maximum weight for that duration.
Noise is another area where the marketing claims need careful interpretation.
The manufacturer’s product page includes both 25 dB and 40 dB claims in different sections. Neither figure is accompanied by a sufficiently detailed independent measurement protocol.
Fortune’s testing team found the treadmill very quiet during its evaluation. Its tester gave the noise experience a 5 out of 5 and reported that the motor and incline adjustments produced little noticeable noise.
That is positive hands-on evidence, but it is one tester’s assessment rather than a published laboratory decibel measurement.
There is also a separate CHIP test of the European W50 MR-T25 variant that reported a noticeable belt-rubbing noise. Because that test identifies MR-T25 rather than the exact US model MR-T25B2-US, it should be treated as a regional-variant warning rather than direct proof of the US version’s noise performance.
The practical conclusion is that the W50 has encouraging independent noise feedback, but buyers should not interpret the manufacturer’s 25 dB or 40 dB figures as guaranteed operating noise in every room.
Floor type, maintenance, incline, and walking speed may influence the sound and vibration experienced at home.
Controls, display, and MERACH app
The W50 offers several ways to manage a workout.
The magnetic remote is the primary control accessory. It handles speed adjustment, incline changes, and start/stop functions.
Its magnetic attachment is useful because the remote can be stored on the machine rather than left on a nearby desk or table.
The LED display provides basic workout information:
-
Speed.
-
Time.
-
Distance.
-
Estimated calories.
-
Incline level.
The estimated calorie figure should not be treated as a direct measurement of energy expenditure.
The MERACH app provides additional functionality through Bluetooth connectivity.
According to the manufacturer documentation, the app offers workout tracking, guided programs, and virtual scenery experiences.
For users who want a more interactive home-walking setup, these features can make the treadmill more engaging than a remote-only machine.
However, app integration also introduces a small dependency. Users who prefer a simple machine that operates entirely without a smartphone may not benefit much from the extra digital features.
The remote remains important because it provides convenient control without opening the app.
Performance evidence from independent testing and owners
The W50 has more useful external performance feedback than a number of lesser-documented walking-pad models.
The strongest hands-on assessment identified during research comes from Fortune’s walking-pad testing team.
Fortune selected the NovaWalk W50 as its Best Walking Pad Overall and assigned it a score of 4.5 out of 5.
The tester highlighted three main strengths.
First, setup was straightforward. The machine arrived ready to use, with the remote already paired and supplied with a battery.
Second, the reviewer was impressed by the noise level. The tester described the machine as exceptionally quiet, including when adjusting the incline.
Third, the tester found the walking belt sufficiently spacious even at a height above 6 feet.
However, Fortune also identified two disadvantages: the purchase price may be higher than basic walking pads, and the machine does not fold.
What owner feedback reveals
Retailer feedback is more mixed than the positive hands-on review.
At the time of research, Walmart displayed a 4.1 out of 5 rating from 83 ratings and 31 written reviews for its W50 listing.
The positive feedback includes ease of initial setup, straightforward controls, and suitability for home walking.
There are also complaints worth considering.
One verified Best Buy purchaser reported belt slippage during use and eventual failure after approximately seven months.
Another verified purchaser reported jerking after approximately three weeks, followed by overheating, and dissatisfaction with the proposed motor-replacement solution.
These are individual reports, not evidence that every W50 will develop the same problems.
Other purchasers reported a quieter experience and positive results when using the incline.
The contrast is important: the independent test team’s favorable experience does not eliminate the possibility of reliability or customer-support problems encountered by individual owners.
Buyers should therefore pay attention to the retailer’s return window and the manufacturer’s warranty rather than relying on product ratings alone.
Maintenance, compatibility, and safety
The W50 requires some ongoing maintenance.
The user manual recommends lubricating the walking belt approximately every three months or after 50 hours of use, whichever comes first.
It also provides troubleshooting guidance for common problems, including:
| Problem | Possible cause | Recommended action |
|---|---|---|
| Machine does not power on | Loose cable or power issue | Check the connection and main switch |
| Belt slips or stops | Belt tension or lubrication issue | Follow the manual’s adjustment and lubrication instructions |
| Unusual operating noise | Loose components or belt friction | Check fasteners and belt lubrication |
| E14 error | Possible controller malfunction | Disconnect power for five minutes and restart; contact support if the error continues |
The manual advises placing the treadmill on a flat, stable surface and unplugging it before cleaning, moving, or maintaining it.
Keep children and pets away from the moving belt.
Consumer Reports’ W50 specification listing also does not identify a safety key or handrails.
This matters for users who rely on a physical handrail for support. The W50 is an open walking platform, not a treadmill with a built-in support rail.
People who need additional support should choose a different configuration rather than assuming the wide belt and heavy frame provide the same assistance as a handrail.
For electrical compatibility, check the product label and the supplied documentation for the exact US unit before connecting it.
Warranty, returns, and ownership costs
The manufacturer’s warranty policy is more favorable than a basic one-year parts-only arrangement, provided buyers complete the additional registration step.
MERACH’s current US warranty policy provides:
| Coverage | Published terms |
|---|---|
| Initial warranty | 1 year |
| Covered components | Structural frame and other parts/components |
| Extended coverage | Additional 1 year for registered members |
| Maximum advertised coverage | 2 years |
The manual hosted on Manuals.plus describes a one-year warranty, while the current official warranty page explains the additional year available through registration.
Buyers should therefore save their proof of purchase and complete the registration requirements rather than assuming the extended warranty activates automatically.
The official direct-purchase return policy advertises a 30-day home trial.
However, the terms have conditions:
-
The product must be returned within the applicable 30-day period.
-
Original packaging is required.
-
The product must be undamaged and suitable for resale.
-
Accessories and included items must be returned.
-
Buyers are responsible for return shipping when the return is for personal reasons.
-
Damaged or defective arrivals should be reported within 24 hours with supporting photographs or video.
These conditions matter because the W50 is a relatively heavy machine. Shipping it back can be inconvenient even when the advertised trial period looks generous.
The policy also applies to purchases made directly through MERACH’s official website. Purchases from Amazon, Walmart, Best Buy, or other sellers are subject to the relevant retailer’s return policy.
Price and value
At the time of research, the official MERACH US product page displayed a promotional price of $299.99, reduced from a displayed regular price of $479.99.
This is a direct-site price snapshot checked on November 4, 2026, not a guaranteed price across other retailers.
At that advertised price, the W50 offers a combination of features that makes it worth comparing with other incline walking pads.
Its value comes mainly from:
-
Automatic incline up to 12%.
-
A 16.5-inch-wide walking belt.
-
A 400-pound manufacturer-rated capacity.
-
A continuous motor rating of 1.25 HP.
-
App and remote controls.
-
A registration-based extended warranty.
However, value is not determined by specifications alone.
The non-folding frame, 69.2-pound weight, and limited 4 mph top speed may make another treadmill a better purchase for someone who wants easy storage or running capability.
