Choosing the right under-desk treadmill can transform your home office or workspace. With more people working from home, staying active is a challenge. Under-desk treadmills help you walk while working, improving health and productivity. Two popular models—Merach W50 Walking Pad and Walkingpad R2—are often compared. But which is truly better for your daily needs? This guide will break down the features, specs, and unique points of both treadmills, covering 50 critical aspects. You’ll learn the differences, discover non-obvious insights, and get practical advice for choosing the best fit.
Design & Build Quality
1. Frame Material
The Merach W50 uses a steel frame with ABS plastic, making it sturdy and lightweight. The steel gives a good balance between strength and flexibility, while the ABS plastic helps keep the cost and weight down. The Walkingpad R2 features an aluminum alloy frame, which feels more solid and premium but is heavier. Aluminum alloy is resistant to rust and dents, making it suitable for long-term use, especially if you move the treadmill around often.
2. Foldability
The Walkingpad R2 has a double-fold design, folding in half for easy storage. This lets you slide it under most beds or couches. The Merach W50 folds flat but doesn’t fold in half, so it needs more storage space. If you live in a small apartment or need to store your treadmill often, the foldability difference becomes very important.
3. Maximum User Weight
Merach W50 supports up to 220 lbs (100 kg). Walkingpad R2 handles up to 242 lbs (110 kg), making it better for heavier users. If your weight is close to the maximum limit, always choose a treadmill with a higher capacity for safety.
4. Dimensions (unfolded)
Merach W50 measures 56″ x 21″ x 5″. Walkingpad R2 is 59″ x 21″ x 5.5″. The R2 is slightly longer and taller. This extra length is helpful for users with a longer stride or those who want more comfort while walking or jogging.
5. Dimensions (folded)
Merach W50 folds to 56″ x 21″ x 5″. Walkingpad R2 folds to 32″ x 21″ x 5.5″. R2 is much more compact when folded. This means you can store the R2 vertically or horizontally, while the W50 usually needs to lie flat and takes up more floor area.
6. Weight
Merach W50 weighs 55 lbs (25 kg). Walkingpad R2 is heavier at 77 lbs (35 kg). The extra weight in R2 comes from its sturdier build and larger motor. For some people, moving the R2 alone can be difficult, especially if you need to carry it up stairs.
7. Portability
Merach W50’s lighter weight and built-in wheels make it easier to move. You can roll it from room to room without much effort. Walkingpad R2’s weight can be a challenge, though its wheels help. If you plan to move your treadmill often, the W50 is more convenient, but the R2 is manageable if you don’t need to move it regularly.
8. Color Options
Merach W50 comes mainly in gray, which fits most modern interiors but offers less choice for those who want a stylish look. Walkingpad R2 offers black and white options, making it easier to match with your furniture or home office color scheme.
9. Safety Features
Both models have safety locks and emergency stops, but the R2 includes extra safety sensors. These sensors help detect when you step off the treadmill, automatically pausing the belt for extra security—an important feature if you have kids or pets around.
10. Build Durability
Walkingpad R2’s aluminum build gives it a longer lifespan. Even with daily use, it resists wear better. Merach W50’s plastic parts may wear faster, especially if used heavily or moved often. Over time, the difference in materials can mean fewer repairs and less worry about the treadmill breaking down.
Performance & Motor
11. Motor Power
Merach W50 uses a 2. 5 HP motor, while Walkingpad R2 has a 2. 25 HP motor. The W50’s motor is slightly stronger on paper, but real-world performance is similar due to differences in treadmill design. For most users, both motors are powerful enough for walking, but W50 might handle heavier loads with less strain.
12. Maximum Speed
Merach W50 offers speeds from 0. 5–4 mph. Walkingpad R2 ranges from 0. 5–6. 2 mph, making it better for jogging. If you want to use your treadmill for light running or brisk walks, the R2 gives you more options.
Most under-desk treadmills top out at walking speeds, so R2’s higher speed is a notable advantage.
13. Minimum Speed
Both start at 0. 5 mph, great for slow walking during work. This low speed is useful if you’re typing or need to focus, as it lets you move without losing balance.
14. Noise Level
Merach W50 is quieter (under 55 dB) compared to R2 (about 60 dB). This matters in shared offices or for people taking calls. For example, if you’re in a meeting, the extra 5 decibels can make a difference, especially if your workspace is not soundproof.
15. Motor Technology
R2 uses a brushless motor, which is smoother and longer-lasting. Brushless motors also require less maintenance and generally produce less friction, resulting in a longer machine life. W50’s motor is brush-type, which can wear out faster and may need servicing after a couple of years of heavy use.
16. Power Consumption
Merach W50 uses less power (600W) than R2 (800W), making it more energy-efficient. If you use the treadmill for several hours daily, this can add up to noticeable savings on your electricity bill over the months.
17. Cooling System
R2 features a better cooling system, reducing overheating during longer sessions. This is important if you plan to walk or jog for an hour or more, as overheating can lead to the treadmill automatically shutting off to protect the motor.
18. Speed Adjustment
Both have remote controls for speed, but R2’s controls are more responsive. The R2’s remote also has a sleeker design, with buttons that are easier to press without looking, which is helpful if you adjust speed while working.
19. Continuous Use Time
R2 can run for up to 2 hours without overheating. W50 needs a break after 90 minutes. If you share the treadmill with family or coworkers, R2’s longer run time is a practical plus.
20. Incline Options
Neither offers incline, which is common for under-desk treadmills. If you want to simulate hill climbing, you’ll need a different type of treadmill.
Walking Surface & Comfort
21. Belt Width
Walkingpad R2 has a wider belt (17″) than W50 (15. 5″), offering more walking room. A wider belt gives you more side-to-side movement, which feels safer and more natural, especially if you sometimes drift while walking.
22. Belt Length
R2’s belt is longer (47″), while W50 is 45″. R2 feels more comfortable for taller users or those with a longer stride, as you’re less likely to step off the end of the belt by accident.
23. Cushioning
R2 uses multi-layer cushioning for joint comfort. The extra padding absorbs shocks, which is helpful for people with knee or ankle issues. W50 has basic cushioning, which is fine for short walks but can feel hard during longer sessions.
24. Anti-slip Surface
Both treadmills have anti-slip walking surfaces, but R2’s feels grippier. This is important if you walk in socks or don’t always wear shoes, as it helps prevent slips.
25. Shock Absorption
Walkingpad R2’s advanced shock system reduces impact, making it better for those with knee issues. If you have joint pain or are recovering from injury, this could be a deciding factor.
26. Side Rails
R2 has sturdy side rails for balance. These rails can be helpful when starting or stopping your walk. W50 has smaller, less supportive rails, which may be fine if you always hold onto your desk for balance.
27. Walking Experience
R2’s wider belt and cushioning make it more comfortable for long sessions. If you want to walk for an hour or more, the difference is noticeable. W50 works well for shorter, casual walks.
28. Belt Maintenance
W50’s belt needs more frequent lubrication. Over time, this can be a hassle if you don’t want to do regular maintenance. R2’s belt is self-lubricating, which means you spend less time on upkeep and more time walking.
29. Belt Replacement
R2’s belt is easier to replace. You can often do it yourself with basic tools. W50 requires professional help, which can mean extra cost if the belt wears out.
30. Belt Durability
R2’s belt lasts longer due to higher-quality materials. If you plan to use your treadmill every day, this helps avoid the trouble of frequent repairs or replacements.
Technology & Connectivity
31. App Integration
R2 connects to the KS Fit app for tracking steps, calories, and speed. The app offers history, trends, and reminders. W50 uses the Merach app, but it’s less advanced and sometimes loses connection. For people who like to track progress and set goals, R2’s app is a real advantage.
32. Bluetooth
Both models offer Bluetooth, but R2’s is more stable and pairs quickly with most devices. This means less frustration setting up your treadmill each day.
33. Remote Control
R2’s remote is sleeker, with better responsiveness. It fits in your hand easily and can be used without looking. W50’s remote is basic and may feel less comfortable, with buttons that sometimes require a firm press.
34. Display Type
R2 features an LED display on the side, which is bright and easy to see even in low light. W50 uses a basic LCD on the deck, which can be harder to read if you have glare from windows or lights.
35. Display Information
R2’s display shows speed, time, distance, and calories. You get a complete picture of your workout. W50 only shows speed and time, so you may need another app or device for tracking calories or distance.
36. Step Tracking
R2 counts steps accurately, which is important for users who set daily step goals. W50 sometimes misses steps, especially if you walk slowly or with a short stride.
37. Data Export
R2 exports data to fitness apps. This makes it easier to sync with Apple Health, Google Fit, or other platforms. W50 doesn’t support data export, so you’re limited to viewing data in its own app.
38. App Compatibility
R2 works with Android and iOS. W50’s app sometimes struggles on Android and may disconnect or fail to sync data. If you use Android, R2 is more reliable.
39. Firmware Updates
R2 receives regular software updates, fixing bugs and adding features. W50 rarely updates, so you may miss out on future improvements.
40. Smart Features
R2 has auto-stop if you step off, adding peace of mind if you forget to turn it off. W50 lacks this feature, so you need to remember to stop the belt manually.
Usability & Practicality
41. Setup Process
W50 is easier to set up, needing less assembly. You can usually start walking in minutes. R2 takes longer due to foldable parts and sometimes requires two people to assemble safely.
42. Under-desk Fit
Both treadmills fit under most desks, but R2’s folded height is better for small spaces. If your desk is low or you need to slide the treadmill away after use, R2 is more practical.
43. Walking/jogging Use
R2 supports jogging up to 6. 2 mph. This makes it suitable for light runs or brisk walks. W50 is limited to walking, which is fine for most office use.

Practical Guidance For Choosing
When picking an under-desk treadmill, think about:
- Your fitness goals: If you only want to walk, W50 saves money and maintenance effort. If you plan to jog or need more comfort, R2 is better and will keep up as your fitness improves.
- Space in your home/office: R2 folds smaller, so it fits better under desks or in closets. This is especially useful if you need to keep your space tidy or share your living area.
