Walking Pad X25: Ultimate Compact Treadmill Review Today

The walking pad x25 is a double-fold treadmill designed for people who want genuine indoor walking and running capability without permanently dedicating a large area to exercise equipment. Its 10 mph maximum speed, 51.9 × 19.6-inch running belt, 300 lb advertised weight capacity, and vertical storage design make it substantially more capable than a typical under-desk walking pad. However, conflicting motor specifications, the absence of side handrails on the standard model, and a relatively firm running deck deserve attention before buying.

This review covers the standard WalkingPad X25, also identified as X216 on the US product page. It does not combine specifications from the X25+ version, which adds foldable side handrails and weighs more.

Walking Pad X25 review: Quick verdict

The WalkingPad X25 is a compelling option for apartment dwellers and home exercisers who want a compact treadmill that can handle more than casual walking.

Its biggest advantage is the double-folding frame. The treadmill folds vertically, reducing its storage footprint to approximately 10.1 × 30.4 × 40.3 inches. When unfolded, it provides a 51.9 × 19.6-inch running surface and reaches speeds up to 10 mph.

That combination makes it more versatile than walking pads limited to 3–4 mph.

The 300 lb advertised weight capacity also gives it a relatively substantial specification for a foldable treadmill weighing 104 lb.

However, it has meaningful compromises:

• The standard X25 has no side handrails.

• The running deck has relatively firm cushioning.

• The motor horsepower specification is inconsistent between manufacturer product pages.

• The treadmill is not intended to replace a full-size machine for high-mileage running or race training.

The X25 makes more sense for someone who needs a treadmill that can actually support jogging and running. Buyers who only want to walk beneath a standing desk are paying for capabilities they may never use.

Walking Pad X25 specifications and exact model

The standard X25 belongs to KingSmith’s WalkingPad running-treadmill lineup.

The US manufacturer storefront identifies the product as the WalkingPad X25 Double-Fold Running Treadmill and labels the standard selection X25 (X216).

The standard version is available in different colors, including gray, black, and blue on the manufacturer’s listing. Color selection does not establish a different performance configuration.

The most important distinction is between the X25 and X25+:

The X25+ is not simply a different color or package. Its additional handrails affect the machine’s overall configuration and weight.

This review concentrates on the standard X25 because it is the more compact and lighter version.

Verified key specifications

Important motor specification conflict

The US WalkingPad product page advertises a 4.5 HP brushless motor. However, the KingSmith product page lists a 1.5 HP brushless motor, and TreadmillReviewGuru also identifies the motor as 1.5 HP in its hands-on review.

These figures cannot be confidently reconciled from the available documentation. The US page does not clearly establish whether its figure represents peak output, a maximum marketing rating, or another measurement.

For buyers comparing treadmills by continuous horsepower, this is an important missing detail. Do not treat the advertised 4.5 HP as verified continuous motor output.

The safest specification to publish is a brushless motor with an unresolved horsepower rating.

Design, construction and double-fold storage

The X25’s main design advantage is its unusual folding system.

Unlike conventional folding treadmills that raise their running deck toward an upright position, the X25 folds its deck in half and then folds the assembly vertically.

The result is a relatively narrow storage profile.

Unfolded dimensions: 60.8 × 30.4 × 40.3 inches.

Folded dimensions: 10.1 × 30.4 × 40.3 inches.

These figures matter because storage convenience is one of the main reasons to consider the X25 over a conventional home treadmill.

When folded, the machine can be positioned upright against a suitable wall or stored in a closet with enough clearance.

The treadmill also includes transport wheels. However, at 104 lb, it should not be treated as a lightweight piece of equipment.

Rolling it across a hard floor is different from carrying it up stairs. Buyers living in apartments without elevators should consider where the machine will be stored and how it will be moved before ordering.

Frame construction

KingSmith describes the X25 frame as an aluminum-alloy structure.

TreadmillReviewGuru’s testing found that the deck has eight adjustable leveling feet. The reviewers needed to adjust one foot to stabilize the treadmill on their testing-room floor. Once adjusted, they did not report rocking or clanking during their running evaluation.

This is a useful practical finding because floor unevenness can affect stability independently of the treadmill’s frame construction.

Running surface

The 51.9 × 19.6-inch belt is considerably larger than the walking surface found on many compact under-desk machines.

It provides more room for normal walking and jogging strides.

However, it remains shorter than the 60-inch running decks commonly recommended by the independent reviewer for dedicated running.

The width is also important. At 19.6 inches, it provides a reasonable running area for a compact machine, but people accustomed to commercial treadmills may notice the difference.

Features and practical use

10 mph speed range

The X25 reaches a maximum speed of 10 mph, equivalent to approximately 16.1 km/h.

That is a meaningful difference from basic walking pads that stop around 3–4 mph.

Its speed range allows several types of exercise:

• Slow and moderate walking.

• Brisk walking.

• Jogging.

• Shorter running sessions.

• Faster indoor running for users who are comfortable with the compact belt.

The X25 is not designed specifically for marathon training or extended high-mileage workouts. Its motor, folding structure, and running deck are better understood as a space-saving solution for everyday home exercise.

TreadmillReviewGuru’s reviewer reported being able to run at 8.5 mph or faster on the X25. Another tester, who was 6 feet 5 inches tall, could comfortably reach 6 mph.

These findings are useful examples of how stride length affects fit. They are not a guarantee that every runner of similar height will find the belt comfortable.

SpeedDial control

The SpeedDial is one of the more practical features of the X25.

Instead of relying exclusively on buttons, the machine uses a central rotary control to adjust speed.

Turning the dial slowly changes speed in approximately 0.1 mph increments. Faster rotation can jump between larger preset speeds.

The dial is convenient when making adjustments during a workout because users do not need to navigate a series of small buttons.

However, the independent reviewer reported occasional delayed responses when pressing the dial to start or stop the treadmill. Most presses worked normally, but a few required a second attempt.

The review also found that control inputs produce audible beeps and that the sounds could not be disabled.

These details are worth considering if the treadmill will be used in a quiet apartment or shared living space.

KS Fit app and Bluetooth connectivity

The X25 supports the KS Fit application through Bluetooth.

The app provides a way to monitor workout information and adjust treadmill settings from a phone.

The independent review describes several functions:

• Workout tracking.

• Pace and speed information.

• Distance and step information.

• Stride-rate tracking.

• Workout goals.

• Preset interval programs.

• Custom workout creation.

• Maximum-speed restrictions.

• Startup-speed settings.

• Child-lock functionality.

The app also supports a no-load stop function, which stops the belt when the machine detects that nobody is using it for a period of time.

This gives the X25 more functionality than a basic manually controlled walking pad.

However, app-dependent operation creates another ownership consideration. Buyers should make sure they can connect their smartphone and understand how the speed-control and safety settings work before exercising.

The physical SpeedDial and safety key remain important even when using the app.

OLED display and device holder

The X25 includes an OLED screen integrated into its front console.

The independent review describes the display as showing time, speed, distance, and calories.

A separate device holder accommodates a phone or tablet, making it easier to follow a workout, watch content, or use the KS Fit application.

The display is relatively straightforward rather than a large entertainment console.

This suits people who want basic exercise feedback without paying for a large touchscreen system.

Calorie readings should still be treated as estimates, not exact measurements of energy expenditure.

Safety key

The X25 includes a removable safety key.

According to the independent review, the key needs to be connected for the treadmill to operate. The clip can be attached to clothing, allowing the belt to stop if the key is pulled out.

This is an important feature, particularly because the standard X25 lacks side handrails.

The presence of a safety key does not eliminate the need to maintain a stable walking or running position. Users should understand the controls and stopping procedure before increasing speed.

Performance evidence: What independent testing found

TreadmillReviewGuru published a hands-on X25 review on October 1, 2024. The publication states that WalkingPad supplied the treadmill for testing and that its review also uses affiliate links.

The test findings provide useful context beyond manufacturer marketing claims.

Running performance

The reviewer found that the X25 could accommodate walking, jogging, and lighter running.

The treadmill was not recommended for long-distance race preparation or heavy daily training. Its compact deck and motor output place practical limits on the type of running workouts it can support.

This is a reasonable distinction.

A treadmill reaching 10 mph does not automatically make it equivalent to a full-size running machine. Maximum speed is only one part of performance.

Motor responsiveness

The reviewer described the 1.5 HP brushless motor as relatively quiet and responsive.

However, they also noted that its speed adjustments were not as quick as those of higher-powered treadmills.

For casual running sessions, that limitation may not be a major problem. For workouts requiring rapid speed transitions, it becomes more relevant.

Deck cushioning

One of the more important negative findings was the firm running surface.

The reviewer described the deck cushioning as minimal, with less give than larger treadmills that have elevated decks.

The folding hinge was less noticeable than on some other WalkingPad models, which is a positive finding for foot placement.

Nevertheless, people who prefer a softer treadmill feel may find the X25 relatively firm.

Stability and portability

The reviewers found that the treadmill rolled well across hard floors and workout mats.

Its smaller transport wheels were less convenient on thick carpets.

The eight adjustable leveling feet helped improve stability on their testing-room floor.

The biggest portability limitation remains its 104 lb net weight. Although the folding design makes repositioning easier, the treadmill is not especially convenient to carry frequently.

Overall performance assessment

The independent review rated the X25 at 74/100.

Its strongest category was dimensions and storability, while workout experience, specification features, onboard training, and build quality received lower individual assessments.

This is consistent with the product’s intended purpose: A compact treadmill that can support genuine running, rather than a machine designed to compete with larger commercial-style models.

Compatibility, sizing and setup considerations

The X25 requires more planning than its folded dimensions might suggest.

Floor space during use

At 60.8 inches long and 30.4 inches wide, the treadmill requires a reasonably clear operating area.

The folded footprint is much smaller, but users still need sufficient room to unfold the deck and exercise safely.

Do not measure only the storage location. Measure the operating area as well.

User height and stride length

The 51.9-inch belt is relatively generous for a foldable treadmill, but it is not a full-length running deck.

Shorter-stride runners may find it suitable for faster workouts. People with longer strides should be more cautious.

The independent review’s testing observations reinforce the importance of considering actual stride length rather than relying on height alone.

Weight capacity

The published maximum user capacity is 300 lb.

This is a manufacturer specification, not a guarantee that every user at or below this weight will experience identical performance.

Users should follow the product’s maximum limit and avoid exceeding it.

Flooring and leveling

The adjustable leveling feet should be checked during initial setup.

A treadmill placed on an uneven surface may rock or produce additional noise, even when the frame itself is properly constructed.

The manufacturer also recommends appropriate clearance and a suitable installation surface.

Because the X25 weighs 104 lb, choosing its permanent exercise location before unfolding it is practical.

Electrical requirements

The US manufacturer’s product specification lists 110V operation.

Use the power supply and electrical setup specified for the US variant. Do not assume that international WalkingPad versions have identical voltage configurations.

The treadmill should be connected to an appropriate outlet, with the power cord kept clear of moving components and walking paths.

Strengths and limitations

Pros

• 10 mph maximum speed.

• 300 lb advertised user capacity.

• 51.9 × 19.6-inch running surface.

• Double-fold vertical storage design.

• Fully assembled according to the manufacturer.

• SpeedDial provides convenient speed adjustment.

• KS Fit app offers workout tracking and controls.

• Removable safety key.

• Adjustable leveling feet.

• More capable for running than basic walking pads.

Cons

• No side handrails on the standard X25.

• 104 lb machine weight still makes frequent carrying inconvenient.

• Firm deck cushioning.

• Small transport wheels are less convenient on thick carpet.

• Dial controls occasionally required a second press in independent testing.

• Audible control beeps cannot be disabled according to the review.

• No adjustable incline.

• Conflicting motor horsepower specifications.

• One-year limited warranty is shorter than some buyers may expect for this price category.

• Not intended for high-mileage running or marathon training.

The main trade-off is between storage convenience and full-size treadmill performance.

The X25 provides more running capability than most walking pads, but its compact dimensions and relatively firm deck remain noticeable limitations.

Alternatives: X25+ and other treadmill configurations

The most direct alternative is the X25+.

It retains the same advertised 10 mph top speed, 300 lb capacity, and 51.9 × 19.6-inch running area.

Its main difference is the addition of foldable side handrails.

The X25+ weighs 119 lb, which is 15 lb more than the standard X25.

For people who want extra physical support during faster workouts, the X25+ may be the more appropriate choice.

However, the standard X25 remains preferable for buyers who want a lighter machine and do not need side handrails.

People who regularly train for longer running distances should consider a conventional treadmill with a 60-inch or longer deck, a more substantial frame, and a clearer continuous-duty motor specification.
