MERACH W50 Walking Pad Review
The MERACH W50 Walking Pad is a compact under‑desk treadmill that behaves more like a serious piece of gym equipment than a flimsy stepper. It’s built around a 3.5 HP brushless motor, a 12% automatic incline and a 400 lbs weight capacity, making it a strong option for heavier users or anyone who wants a rock‑solid walking platform at home.
Instead of a tiny, cramped belt, the W50 gives you a 16.5" x 41.3" walking area, so your stance feels natural even when you pick up the pace. You can use it flat for steady under‑desk walking or add incline for more intense workouts without changing machines.
What’s Actually Good About the MERACH W50
After looking at user feedback and specs, the W50 clearly targets people who want under‑desk convenience but with far better stability, power, and training options than the ultra‑budget walking pads.
The Design Thing
The frame uses a rigid, non‑folding deck and steel structure, which is how it manages that 400 lbs weight limit without feeling bouncy. That extra sturdiness makes a big difference if you’ve ever tried a cheaper pad that flexes in the middle or feels like it’s bowing under you.
The 16.5"‑wide belt also gives more lateral room than the 13–14" belts you see on many budget models, so you don’t feel like you’re having to consciously “walk a tightrope” to stay centred. At up to around 4.0 mph, it feels like a compact treadmill rather than a toy.
The Motor & Noise Level
The 3.5 HP brushless motor is designed to be quiet and efficient, which is crucial in a home office or apartment setting. Users and reviewers generally describe the sound as a low hum rather than the clunky grinding you get from older or cheaper units.
Brushless motors also tend to run cooler, and the W50 is rated for extended use (up to many hours continuously), so you can walk through a big chunk of your workday without worrying about an auto‑shutoff cutting your session short.
The 12% Auto‑Incline
This is the headline feature. Most walking pads are flat forever; the W50 gives you automatic incline up to 12%, controlled from the remote. That means you can start flat under your desk, then bump the incline in short bursts to increase calorie burn and raise your heart rate without upping speed.
Even a mild incline can make walking feel more like a hike than a stroll, and it’s a smart way to get more training stimulus out of the same floor space. It also lets you train different muscle groups in your calves and glutes compared to flat walking.

Using It Day‑to‑Day
Under‑Desk and Home Use
The speed range is geared towards walking and light power‑walking, which is exactly what most under‑desk users need. Set it slow while you type and take calls, or increase the pace in focused sessions when you’re watching TV or on a podcast.
Because controls are on a handheld remote rather than a big console, you don’t have to lean over or break your stride to adjust speed or incline. That’s ideal when you’re mid‑Zoom‑call and just want to nudge things a little slower or steeper without making a big fuss.
Noise and Vibe in Real Life
Real‑world feedback consistently mentions that the W50 is surprisingly quiet for its power. It’s well‑suited to flats, shared homes, and small offices where you don’t want the whole room hearing every step.
The deck feels firm and confidence‑inspiring rather than bouncy, which makes longer walks more comfortable and less fatiguing on your knees and ankles. Combined with the wider belt, it feels more like a condensed treadmill experience than a compromise.
Does It Actually Work?
The big question with any walking pad is whether it genuinely changes your daily activity level. For many people, the answer with the W50 is yes, because it makes movement frictionless: you can walk during calls, emails, or Netflix without planning a “workout.”
Users report higher daily step counts, more consistent low‑impact activity through the day, mild weight loss over time, and less stiffness from long sitting sessions. It doesn’t replace all intense workouts, but it does convert previously sedentary time into useful movement.

MERACH W50 Walking Pad Talk‑Through
Several independent reviewers and fitness creators have walked through the W50 on video, highlighting how it fits into a home office or living‑room training setup. They tend to focus on the solid build, the smoother belt feel compared to cheaper pads, and how the incline adds genuine workout variety.
Once you’ve seen it in action, it’s easier to visualise exactly how it will sit under your desk, how loud it is in a real room, and how quickly it responds to speed and incline changes from the remote.
What People Love
- Heavy‑duty capacity and stability: The 400 lbs rating and rigid deck give much more confidence for heavier users or anyone who hates wobbly equipment.
- Real 12% auto incline: This opens up hill‑style workouts and makes even low speeds more challenging, all without needing a full‑size incline treadmill.
- Quiet brushless motor: The sound profile is office‑friendly, so you can walk while on calls or in shared spaces without feeling self‑conscious.
- All‑day usability: Designed for long, continuous sessions, so it’s practical for several hours of scattered walking during a workday.
- Under‑desk friendly design: Low profile and integrated wheels make it easy to slide under standing desks or move between rooms.
What’s Not So Great
- Not for full‑on running: With a walking‑focused top speed, this won’t satisfy you if you want fast interval runs or sprint training.
- Heavier, non‑folding deck: The solid build is a plus for stability but means it’s bulkier and heavier than ultra‑compact foldable pads.
- Remote dependence: Like most walking pads, the remote is central to operation, so losing or damaging it can be a hassle.
- Relatively new model: Long‑term durability data is still developing compared to big‑brand treadmills that have been on the market for many years.
My Take
If you just want the absolute cheapest way to walk at your desk, the MERACH W50 will feel like more machine than you need. But if you value stability, higher weight capacity, and the ability to train on a real incline without filling the room with a full treadmill, it hits a very appealing middle ground.
The limited top speed is a deliberate design choice: this is about sustainable, low‑to‑moderate‑intensity movement throughout the day rather than all‑out sprints. For remote workers, apartment dwellers, and heavier users who want a walking pad that feels genuinely solid underfoot, it’s a strong contender.
