Walking Pad Z1: Best Compact Under Desk Treadmill Review

The walking pad z1 from KingSmith is a compact, fold-in-half treadmill designed for home offices, apartments, and people who want to walk indoors without keeping a full-size treadmill on the floor. Its 47.6-inch walking surface, remote and app controls, and slim folding design make it attractive for everyday movement. However, its 242-pound weight capacity, 51-pound machine weight, and lack of a handrail mean it is better suited to controlled walking than running or workouts requiring additional stability.

Quick verdict: Is the Walking Pad Z1 worth buying?

The WalkingPad Z1 is a strong option for people who prioritize compact storage, comfortable everyday walking, and simple under-desk exercise.

Its most distinctive advantage is the folding mechanism. Unlike a conventional flat walking pad that retains its full length during storage, the Z1 folds at the center, reducing its footprint considerably.

The manufacturer lists a 47.6 × 15.7-inch walking surface and a maximum speed of 6 km/h, approximately 3.7 mph. That combination is well suited to walking while working, listening to podcasts, or watching television.

Independent testing by Tom’s Guide supports its suitability for home-office walking. The reviewer reported responsive controls, useful app features, and comfortable walking, while identifying a short power cord, limited remote adjustments, noticeable operating noise, and the inconvenience of moving a 51-pound machine.

The Z1 is less compelling for anyone who needs a higher weight capacity, conventional running speeds, incline training, or a treadmill with stable handrails.

Overall, it offers a sensible balance of walking space and compact storage, provided its weight capacity and walking-only design meet your needs.

Walking Pad Z1 overview and exact model

The WalkingPad Z1 is a foldable walking treadmill produced by KingSmith under the WalkingPad brand.

It belongs to a product family focused on reducing the space required for indoor exercise equipment. The Z1’s central folding mechanism distinguishes it from many inexpensive walking pads that remain rigid when stored.

This review specifically evaluates the WalkingPad Z1 Foldable Walking Treadmill identified on the US WalkingPad and KingSmith websites. It does not automatically apply to the WalkingPad Z3, A1 Pro, C2, or R-series treadmills.

Which Walking Pad Z1 version does this review cover?

The primary reference is the standard Z1 configuration with a 47.6-inch walking surface, a 242-pound manufacturer-listed weight capacity, remote control, and KS Fit app support.

WalkingPad also markets a Z1 White version with closely matching published specifications. A buyer should still verify the exact product identifier and package contents rather than assuming color is the only difference between every listing.

Manufacturer documents contain a discrepancy concerning motor horsepower. WalkingPad’s US website lists a 2.25 HP brushless motor, while KingSmith’s separate product page lists 0.75 HP.

Because these figures have not been reconciled through a model-specific engineering document or independent measurement, neither should be used to claim superior motor performance.

The manufacturer also describes the Z1 as a walking treadmill with a top speed of 6 km/h. Its US listing rounds that figure to 4 mph, although the more precise conversion is 3.73 mph.

For purchasing purposes, 6 km/h should be treated as the documented maximum unless the specific unit’s manual establishes otherwise.

Verified specifications and technical details

The following specifications are published by WalkingPad and are corroborated in important areas by KingSmith and independent coverage.

The listed dimensions are particularly useful because they show the difference between the treadmill’s operating footprint and its stored footprint.

At 56.1 inches long when unfolded, the Z1 still needs adequate space for walking. Folding reduces its length to 31.8 inches, making it easier to place beneath furniture or store in a suitable area.

Its 51-pound weight is also important. Although the Z1 folds into a smaller shape, it is not especially light.

These figures establish the machine’s physical characteristics, but they do not independently verify long-term reliability, sustained motor output, or fitness-tracking accuracy.

Design, construction, and portability

Fold-in-half design saves meaningful floor space

The Z1’s central folding mechanism is its strongest practical feature.

Many basic walking pads use a rigid frame that must be stored at nearly their full operating length. The Z1 instead folds into a shorter package, giving owners more flexibility when the treadmill is not in use.

The folded length of 31.8 inches is particularly useful for small apartments and home offices where exercise equipment must share space with furniture.

A person working in a bedroom, for example, may be able to unfold the treadmill during the day and store it beneath a suitable bed afterward.

However, folded dimensions do not guarantee storage compatibility.

The available space must accommodate the machine’s 22-inch width and 5.4-inch folded height, plus enough clearance to slide or retrieve it without damaging furniture.

Buyers should also confirm the permitted storage orientation in the supplied manual.

The folding mechanism does not eliminate the need for a safe walking area when the treadmill is open. Its full 56.1-inch length must fit comfortably within the intended workout space.

Walking surface and stride accommodation

The Z1 has a listed walking surface measuring 47.6 inches long and 15.7 inches wide.

That is a useful design choice for a compact treadmill because the relatively long belt gives walkers more room for forward movement than the smallest walking pads.

A longer walking surface can be particularly helpful when increasing speed or when a user naturally takes longer steps.

The narrower width remains a limitation. At 15.7 inches, the belt provides less lateral space than a conventional treadmill deck.

That matters when walking while typing, reaching for a mouse, or looking away from the machine.

Even a small change in body position can affect where the feet land, so users should remain aware of the walking surface rather than treating the treadmill like an unrestricted floor.

For everyday walking, the dimensions offer a reasonable compromise between compactness and stride room.

For sustained running or highly dynamic workouts, a wider and longer conventional treadmill is preferable.

Storage wheels and handling a 51-pound treadmill

The Z1 includes transport wheels intended to make moving the folded treadmill more manageable.

Tom’s Guide found the wheels useful when repositioning the machine, but the reviewer also noted that its weight made lifting and carrying inconvenient.

This distinction is important.

A foldable treadmill may occupy less storage space without being easy to lift. Moving it across a level hardwood floor is different from carrying it upstairs or over a high doorway threshold.

Users who expect to move the treadmill frequently should assess the route between the exercise area and storage location.

Carpet, furniture, stairs, and tight spaces may make everyday movement more difficult than the product’s compact appearance suggests.

The Z1 is best suited to a setup where it can be unfolded, used, and rolled into nearby storage without excessive lifting.

Build materials and walking comfort

WalkingPad lists EVA and PET materials as part of the Z1’s shock-absorption construction.

These materials are intended to influence how the walking surface responds to footfalls, although the published information does not quantify the reduction in impact forces.

In independent testing, Tom’s Guide described the treadmill as comfortable during walking and reported a favorable experience over a five-kilometer session.

That is useful firsthand evidence of perceived comfort, but it is not a controlled biomechanical measurement.

Comfort varies with footwear, walking technique, body weight, pace, and individual preference.

A cushioned walking surface should not be interpreted as proof that the treadmill prevents injuries or treats joint problems.

For most buyers, the practical question is whether the walking deck provides a sufficiently stable and comfortable surface for the amount of time they intend to spend using it.

Walking performance and everyday features

Speed range for desk walking and light exercise

The Z1 has a manufacturer-listed speed range of 1–6 km/h, equivalent to approximately 0.6–3.7 mph.

This range covers slow movement during focused desk work, comfortable walking while watching television, and brisk walking when the user is not concentrating on another task.

A relatively low minimum speed is useful because typing and walking simultaneously require coordination. Many people will find it easier to begin at a gentle pace before increasing speed once their walking rhythm becomes comfortable.

The maximum speed may allow limited light jogging for some users, but the Z1 is not designed as a conventional running treadmill. Its narrow walking surface and lack of a supportive handrail make faster activity less appealing than walking at a controlled pace.

The absence of an incline also limits workout variety. Users cannot increase the slope to introduce additional resistance without changing the machine’s configuration, and the Z1 does not provide a manufacturer-documented incline adjustment.

For someone whose main objective is to add walking to a sedentary day, that simplicity is reasonable. For someone building a more demanding fitness program, it may become a limitation.

Remote control versus KS Fit app

The Z1 supports two primary methods of speed adjustment: the supplied remote control and the KS Fit mobile application.

The remote provides a convenient way to operate the machine without bending down. This is particularly useful when walking at a standing desk because stopping to reach the treadmill housing would interrupt the workflow.

However, independent testing found a meaningful difference between remote and app control.

Tom’s Guide reported that the remote changed speed in 0.5 km/h increments, while the app allowed finer 0.1 km/h adjustments. The reviewer preferred an intermediate walking speed that was easier to select through the application.

That distinction matters more than it might initially appear. A walking speed that feels comfortable during casual exercise may become distracting when typing, reading, or using precise computer controls.

Small speed adjustments can make the difference between a walking pace that complements desk work and one that interferes with it.

The remote is suitable for basic operation, while the app provides greater flexibility for users who want to fine-tune their walking pace.

Workout tracking and app functionality

The KS Fit application adds workout information beyond the basic display.

In Tom’s Guide testing, the app provided metrics including speed, elapsed time, distance, estimated calories, step count, pace, and cadence-related information.

These features can help users monitor consistency and adjust their routines according to their goals.

For example, someone working from home might use elapsed time to keep track of walking sessions throughout the day, while distance and estimated steps provide additional context about accumulated movement.

However, treadmill-generated activity metrics should not automatically be treated as laboratory-accurate measurements.

Calorie expenditure is an estimate, and step-count accuracy can depend on how the machine and application calculate movement.

WalkingPad also advertises Apple Watch connectivity through KS Fit. That feature may be useful for people already using Apple’s fitness ecosystem, but buyers should confirm current application compatibility and supported synchronization functions.

The Z1’s basic walking function does not require a sophisticated tracking routine. Users who prefer simplicity can focus on walking time and speed without depending on detailed workout analytics.

Display visibility and controls

The Z1 features an integrated display that presents basic walking information.

Independent testing described the display as readable and useful for monitoring speed, time, distance, and estimated calories while exercising.

The absence of a large upright console contributes to the treadmill’s compact profile and makes it easier to position beneath a desk.

However, the low display position also means users may need to look down to read certain information.

That is not always ideal while walking. Looking downward repeatedly can interfere with posture and awareness of the moving belt.

For desk use, the mobile application may provide a more convenient viewing arrangement if the phone can be placed securely at eye level.

Users should avoid trying to operate their phones or make complex adjustments while moving at a speed that compromises balance.

Operating noise and vibration

Noise is one of the more important considerations for anyone planning to use a walking pad during work calls or in a shared apartment.

WalkingPad markets the Z1’s brushless motor as quiet, but independent testing provides a more cautious perspective.

Tom’s Guide reported an average reading of approximately 57.3 dB using a smartphone sound-measurement application during its testing. The reviewer also noted that the treadmill sounded louder in practice than the manufacturer’s low-noise marketing suggested.

This is a useful real-world observation, although a smartphone application is not equivalent to a calibrated acoustic testing system.

The result also depends on measurement distance, walking speed, room acoustics, background noise, and flooring.

It would therefore be misleading to present 57.3 dB as the universal operating noise of every Z1 unit.

For apartment users, the more important concern may be vibration transmitted through the floor. Footsteps and belt movement can create structural noise even when the motor itself is not especially loud.

A suitable treadmill mat may help protect the flooring and reduce certain vibrations, but it cannot guarantee that neighbors will not hear the machine.

If quiet operation during meetings is essential, the Z1 should be evaluated with realistic expectations rather than purchased on the assumption that it operates silently.

Real-world performance evidence

What independent detailed research found

The Z1 has an advantage over many poorly documented walking pads: independent reviewers have published actual usage experiences.

In June 2025, Tom’s Guide evaluated the treadmill for home-office walking.

The reviewer found it comfortable, responsive to remote and app commands, and useful for accumulating steps during desk-based work.

The article also identified practical limitations. The power cord was relatively short, the remote offered limited adjustment precision, and the machine’s weight made moving it less convenient than its folding design might suggest.

These findings provide a more balanced picture than a specifications table alone.

The Z1’s value comes from making walking accessible within an ordinary home-office routine, not from offering advanced athletic performance.

The independent review supports its suitability for walking but does not establish that every user will experience identical comfort or performance.

Longer-term evidence after nine months

A follow-up article published by Tom’s Guide in March 2026 reported continued use of the same Z1 after approximately nine months.

The reviewer described incorporating the treadmill into regular work-from-home sessions, often walking for at least an hour when using it.

That longer observation period is useful because it provides more evidence than a brief unboxing or single-session evaluation.

It suggests the tested unit remained practical for repeated use over several months.

However, one reviewer’s nine-month experience does not establish a typical product lifespan, a statistically representative failure rate, or reliability across every unit sold.

The result is encouraging but should not be interpreted as proof that the Z1 will remain trouble-free for years.

For buyers intending to use the treadmill extensively, maintenance instructions and warranty support remain important considerations.

What independent testing does not establish

The available hands-on coverage is useful for evaluating convenience, perceived comfort, and ordinary operation.

It does not provide a controlled long-term motor endurance test, a precise measurement of continuous motor output, or statistically representative durability results.

The published noise observation also does not establish performance across different floors, walking speeds, and user weights.

Similarly, positive comments about cushioning do not prove that the treadmill reduces injury risk or provides a measurable medical benefit.

These limitations do not make the Z1 a poor product. They simply define which claims can be supported by available evidence.

The strongest case for the treadmill is its documented folding design, straightforward controls, practical walking dimensions, and favorable independent experiences.

Desk compatibility, sizing, and safety

Will the Walking Pad Z1 fit under a standing desk?

The Z1 is intended for use with adjustable standing desks, but compatibility depends on several measurements.

The unfolded treadmill occupies approximately 56.1 inches in length and 22 inches in width. Buyers must ensure that the machine fits between the desk legs without contacting the frame.

The desk also needs sufficient height adjustment.

Standing on the walking belt raises the user’s position above the floor. If a desk is already near its maximum height during ordinary standing use, adding the treadmill may force the wrists, elbows, or shoulders into an uncomfortable position.

A suitable setup should allow the keyboard and display to remain positioned appropriately while walking.

The desk’s front crossbar, cable tray, and other accessories should not interfere with the treadmill.

The reviewer at Tom’s Guide also reported that the supplied cord was around 2 meters long, which may restrict placement relative to a suitable electrical outlet.

Before buying, measure the available desk space, required desk height, and intended cord route rather than relying only on the treadmill’s folded dimensions.

Is the 242-pound weight limit sufficient?

The Z1 has a manufacturer-listed maximum user weight of 110 kg, approximately 242.5 pounds.

This is a meaningful limitation compared with treadmills designed for heavier users.

The limit should not be exceeded, and buyers should not assume that operating close to the maximum capacity delivers the same experience as operating under a lighter load.

Body weight affects the forces placed on the belt, frame, and motor during walking.

For someone near the stated maximum, it is especially important to follow the manufacturer’s instructions and consider how the machine will be used.

Buyers requiring a higher capacity should select a treadmill with a documented rating that accommodates them rather than relying on a general claim of strong construction.

Is the Z1 safe for beginners?

The Z1’s low starting speed and remote control can make it approachable for beginners, but its lack of an upright handrail deserves attention.

A walking pad requires the user to maintain balance independently.

For someone unfamiliar with moving treadmill belts, changes in speed and the transition between stationary and moving surfaces may take practice.

Beginners should become comfortable using the machine before adding distracting activities such as typing or looking at another screen.

The treadmill should be placed on a stable surface with adequate surrounding clearance. Children, pets, loose clothing, and unsecured cables should be kept away from the moving belt.

People who require regular hand support for balance should consider a treadmill with a suitable handrail rather than assuming a compact walking pad offers equivalent stability.

Strengths and limitations of the Walking Pad Z1

The Z1’s strengths are most meaningful to shoppers who need to store their equipment regularly.

Its fold-in-half design gives it a clear practical distinction from rigid walking pads.

At the same time, the treadmill is not unusually light, and its compact design introduces limitations in width, stability support, and workout intensity.

Those trade-offs are reasonable for controlled walking but less attractive for users with broader training goals.

Alternatives to the Walking Pad Z1

WalkingPad A1 Pro for a different premium configuration

The WalkingPad A1 Pro is another folding under-desk treadmill from the same product family.

It is worth considering for shoppers who want to compare WalkingPad’s different control systems, capacity variants, and construction options.

The A1 Pro has historically been positioned above entry-level models within the lineup, but a higher position in a product range does not automatically establish better comfort or durability.

A buyer should compare the actual version’s walking surface, weight capacity, folding dimensions, and controls before deciding whether the additional expenditure is justified.

The Z1 remains a sensible option when basic walking and compact storage are sufficient.

WalkingPad C2 for another compact folding design

The WalkingPad C2 is relevant to shoppers who want the same general concept of a foldable walking treadmill with a different design.

The main purchasing question is not simply whether the C2 is newer or more visually appealing.

Its usable belt dimensions, weight rating, control functions, and folded size should be compared directly with the Z1.

Someone who prioritizes the longest practical walking surface within a small storage footprint should pay particular attention to those measurements.

The Z1’s documented 47.6-inch walking surface gives buyers a clear reference point for that comparison.

A full-size treadmill with a handrail

A traditional treadmill is the more appropriate alternative when walking is only one part of the intended workout.

An upright treadmill with a handrail may offer greater stability, a wider deck, and a larger range of training speeds.

Some conventional models also provide incline adjustment and more detailed console controls.

The downside is greater space consumption and, often, more demanding storage requirements.

For people with dedicated exercise rooms or those who intend to run regularly, those disadvantages may be acceptable.

A compact walking pad should not be chosen solely because it requires less space if it cannot safely support the intended activity.

Who should buy or skip the Walking Pad Z1?

Buy if you need compact storage and everyday walking

The Z1 is especially relevant to remote workers who want to walk during less demanding computer tasks.

Its fold-in-half design can also appeal to apartment residents who need to reclaim floor space after exercising.

It is suitable for shoppers who prefer simple walking routines, appreciate app-based controls, and have enough room to use the treadmill safely.

The independent testing evidence is another advantage. Buyers can evaluate practical observations about comfort, controls, movement, and operating noise rather than relying exclusively on promotional descriptions.

The strongest fit is someone who wants a walking-only machine, falls within the stated weight capacity, and expects to use it on a stable floor near an appropriate outlet.

Skip if you need running, incline, or added stability

The Z1 is not an appropriate substitute for a running treadmill.

Its maximum documented speed of 6 km/h limits its usefulness for faster exercise, and its narrow belt does not provide the same movement space as a conventional running deck.

Users seeking incline walking should choose equipment that explicitly supports incline adjustment.

The Z1 is also a poor choice for anyone who requires handrail support or exceeds the manufacturer’s maximum user-weight rating.

Finally, buyers who must lift their treadmill frequently should consider its 51-pound weight carefully. Folding improves storage convenience, but it does not remove the physical effort required to carry the machine.

Maintenance, warranty, and ownership costs

Belt maintenance and alignment

Like other motorized treadmills, the Z1 requires attention to belt condition, cleanliness, and correct operation.

WalkingPad includes a wrench and user manual with the machine, according to its published package information. Owners should follow the instructions for their exact unit when checking belt alignment or performing maintenance.

Incorrect belt tension can contribute to slipping, unwanted friction, and uneven tracking.

Lubrication requirements must also follow the manufacturer documentation. Not every treadmill uses the same lubricant or maintenance interval.

If the walking belt begins moving unpredictably, produces unusual sounds, or rubs against the housing, stop using the machine and consult the supplied troubleshooting procedure.

The central folding mechanism should also be kept free from objects that could interfere with opening or closing the treadmill.

Warranty and return policy

WalkingPad advertises a one-year limited warranty for products purchased directly from its US website.

Its published return policy generally allows eligible direct purchases to be returned within 30 days of delivery, subject to the stated conditions.

However, the policy requires return authorization, and shipping responsibilities can depend on the reason for the return.

These distinctions matter because a heavy treadmill can be inconvenient or expensive to send back.

The manufacturer’s direct-purchase policy does not automatically apply to products bought through Amazon, Walmart, or independent retailers. Buyers using another marketplace should review that seller’s return terms.

Before purchasing, confirm the applicable warranty, availability of replacement parts, and procedure for obtaining support.

Storage, flooring, and power requirements

The US-market Z1 specifications list a 110V configuration.

Buyers should confirm that the product offered by their retailer is intended for the US market, particularly when considering an imported unit.

The treadmill should be operated on a stable surface with sufficient clearance and ventilation.

Tom’s Guide noted that the Z1’s low-profile construction deserves consideration when used on carpet, especially thicker carpeting.

The appropriate floor arrangement should follow the manufacturer’s installation instructions.

A compatible treadmill mat may help protect the floor, although it should not obstruct ventilation or interfere with the belt.

When storing the machine, keep the power cable protected and avoid placing heavy objects on the folded treadmill.

Frequently asked questions

Is the Walking Pad Z1 good for beginners?

The Z1 can be suitable for beginners who want controlled indoor walking without a large treadmill. Its adjustable low-speed operation and remote control make basic workouts relatively straightforward.

However, users must maintain their balance without a conventional handrail, so it may not suit people who need additional walking support.

Can you run on the WalkingPad Z1?

The manufacturer lists a maximum speed of 6 km/h, approximately 3.7 mph. This makes the Z1 primarily a walking treadmill.

Although some users may be able to jog lightly at that pace, it is not designed to replace a conventional running treadmill.

Does the WalkingPad Z1 have an incline?

No incline capability is documented for the reviewed Z1 configuration. Buyers who want uphill walking workouts should choose a treadmill with a manufacturer-supported incline feature.

How much space does the WalkingPad Z1 need?

The treadmill measures approximately 56.1 × 22 inches when unfolded, with an overall listed height of 4.1 inches.

When folded, its dimensions are approximately 31.8 × 22 × 5.4 inches.

Additional surrounding clearance is necessary for safe operation and access.

Does the WalkingPad Z1 work without the app?

Yes. The Z1 supports basic operation through its supplied remote control, so users do not need the KS Fit app for ordinary speed adjustments.

The application adds finer speed control and workout information.

Is the WalkingPad Z1 quiet enough for an apartment?

The Z1 is designed for indoor walking, but it is not silent.

Independent testing reported noticeable operating sound and an approximate 57.3 dB average smartphone-app measurement under the reviewer’s conditions.

Actual noise and floor vibration will vary with the environment, so buyers should not assume that the machine will be inaudible to nearby residents.

Conclusion

The Walking Pad Z1 is a worthwhile choice for home-office users and apartment residents who want a compact treadmill for everyday walking. Its 47.6-inch walking surface, fold-in-half design, remote and KS Fit controls, and favorable independent usage reports make it appealing for simple indoor exercise. However, its 242-pound capacity, 51-pound machine weight, restricted walking width, and lack of incline or handrail support limit its versatility. Choose the Z1 if convenient storage and controlled walking are your priorities. For running, higher weight capacity, or greater stability, a different treadmill is the better investment.
