Walking Pad A1: Foldable Under Desk Treadmill Essentials

The walking pad a1 is a compact folding treadmill designed for indoor walking, particularly in homes where a conventional treadmill takes up too much space. Its main attractions are a 47-inch walking surface, a maximum speed of approximately 3.75 mph, automatic speed adjustment through foot-position sensors, and a folding frame that makes storage easier.

However, the original A1 should not be confused with the newer A1 Pro. It uses a brushed motor, has different control capabilities, and was originally marketed with a lower weight capacity. The model is also no longer listed on the manufacturer’s U.S. store, which makes warranty coverage, replacement parts, and the condition of secondhand units important purchasing considerations.

This review focuses on the original A1 as a walking treadmill, not a running machine. It uses manufacturer specifications, available documentation, and a published owner review. No new detailed research was performed.

Walking pad A1: Quick verdict

The original WalkingPad A1 is a practical design for people who want a walking treadmill that can be folded and stored beneath suitable furniture.

Its biggest advantage is space efficiency. The machine measures approximately 56.5 inches long when unfolded and folds to roughly 32.5 inches long. Its 47-inch walking surface is considerably more useful for ordinary walking than a very short compact treadmill deck.

The pressure-sensing speed-control system is another distinctive feature. Instead of relying entirely on buttons, the machine can adjust its speed according to where the user stands on the belt.

However, this system requires some familiarity. Users need to understand the front, middle, and rear walking zones before relying on automatic speed adjustment.

The original A1 also has meaningful limitations:

• Maximum speed is approximately 3.75 mph.

• There is no fixed handrail.

• The original model uses a brushed motor.

• The manufacturer no longer lists it as a current U.S. product.

• Published weight-capacity and app-compatibility information is inconsistent.

Buy it if you find a properly functioning original A1 at a reasonable secondhand price, need a compact walking treadmill, and can verify its specifications and condition.

Skip it if you need a currently supported product, a higher weight capacity, dependable app connectivity, a handrail, or a treadmill for running.

Product overview and exact variant

The original WalkingPad A1 belongs to KingSmith’s early generation of foldable walking treadmills.

Its design differs from conventional treadmills because the deck folds horizontally across the center. This reduces the length required for storage without requiring the user to remove a running platform or disassemble the machine.

The original A1 was marketed in a silver or gray finish, with a display integrated into the front housing.

The manufacturer distinguishes the A1 from the A1 Pro in several important ways:

The original A1 and A1 Pro look similar, but their motors, controls, and original capacity ratings are not interchangeable. The manufacturer currently identifies the A1 Pro as the available successor.

For buyers searching for the original A1, checking the actual model name is especially important when browsing used listings. Some sellers use A1, A1 Pro, and WalkingPad generically even when describing different machines.

Walking pad A1: Verified specifications

The manufacturer’s U.S. comparison article and the available model-specific documentation provide the following specifications.

There are two important discrepancies to understand.

Weight capacity: The manufacturer’s current U.S. comparison article identifies 198 pounds as the original A1’s listed capacity. However, the available manual and WalkingPad Canada’s FAQ identify 220 pounds. Buyers should follow the lower limit unless the rating plate and documentation for their specific machine confirm otherwise.

Net weight: The manufacturer’s comparison gives approximately 59.5 pounds, while the available model-specific manual record reports 61.7 pounds. This is a small but relevant difference when planning storage and transportation.

The 746 W figure should also be treated as a listed rated-power specification, not proof of continuous running performance under a particular user load.

Design and folding construction

The original A1’s central advantage is its folding design.

Traditional treadmills usually require a relatively large permanent footprint. The A1 addresses that problem by allowing the deck to fold in half, making the machine easier to store when it is not being used.

Its approximate dimensions are:

The folded dimensions make it suitable for some under-bed and furniture-storage arrangements, provided the available clearance is sufficient.

However, the folded length is not the same as the machine’s total operating footprint. Buyers must check the furniture opening, nearby trim, and access needed to unfold the treadmill.

Build and portability

The WalkingPad A1 has a low-profile construction designed around its folding deck rather than a conventional upright treadmill frame.

Its approximately 60-pound weight is manageable for some users, but it is not particularly light.

A published review by Make Tech Easier describes the treadmill as awkward to reposition because the user must lift one end before rolling it on its transport wheels. The reviewer eventually became comfortable with this process but noted that the machine was too heavy to lift easily.

This is an important distinction for people with limited storage space.

A treadmill that folds flat is convenient to store, but it still needs to be moved into position before use. The A1 is better suited to homes where it has a relatively permanent storage location than to users who want to carry their treadmill between floors.

Features and practical use

Walking pad A1 controls: Foot-pressure sensing and speed adjustment

The original A1 uses pressure sensors to adjust walking speed according to the user’s position on the belt.

The automatic mode is based on three general zones:

• Front zone: Moving toward the front increases the speed.

• Middle zone: Remaining near the center maintains a relatively consistent speed.

• Rear zone: Moving toward the back reduces speed and can bring the belt to a stop.

This differs from the conventional manual controls found on many walking pads.

The idea is to let the user control the pace through natural changes in walking position instead of repeatedly pressing buttons.

However, automatic control is not necessarily suitable for everyone.

New users need to understand how quickly the treadmill responds to changes in position. Moving too far forward or backward may produce a speed change that feels unexpected.

The available manual also describes a manual operating mode with remote control, although the exact control package should be confirmed for the regional version being purchased.

LED display and workout information

The A1 has a display integrated into the front housing.

Available workout information includes:

• Time.

• Speed.

• Distance.

• Calories.

• Steps.

This provides basic feedback without requiring a large treadmill console.

However, the original A1’s display should not be confused with the newer A1 Pro’s control panel or the display-equipped remote found on other WalkingPad models.

The exact information available through a connected application is less certain. The manufacturer’s current U.S. comparison says the original A1 does not have app support, while its Canadian FAQ and an older owner review describe app functionality.

This conflict means app connectivity should not be treated as a guaranteed feature of every original A1. Check the exact unit and its supplied documentation before relying on smartphone tracking.

Manual and automatic workout modes

The A1’s two main modes provide different ways to manage walking speed.

In manual mode, the selected speed remains relatively constant until the user changes it.

In automatic mode, the machine responds to foot position.

The automatic mode is potentially convenient for users who prefer a more responsive walking experience. It may also reduce the need to handle a remote during a session.

However, there is a learning curve.

A published owner review found that the automatic mode required concentration, particularly when the user was distracted by television or another activity. The reviewer also noted that there was no pause function, so stopping and restarting interrupted the current workout statistics.

For beginners, manual mode at a comfortable speed may be the easier starting point. Automatic mode should be explored gradually, following the original unit’s instructions.

Motor performance and walking experience

The original WalkingPad A1 uses a brushed motor with a manufacturer-listed output of 1 HP.

This is a different motor configuration from the A1 Pro’s brushless system.

A brushed motor is a simpler traditional electric motor design, but it has components that experience mechanical wear over time. This does not automatically mean the A1 will fail prematurely; it means motor construction and maintenance history are worth checking when purchasing an older unit.

The maximum speed of approximately 3.75 mph establishes the product’s intended purpose.

That range can accommodate slow walking and brisker indoor walking, but it does not make the A1 suitable for regular running.

The machine also has no adjustable incline, so users cannot increase the belt’s gradient to create hill-walking workouts.

What independent use reports indicate

Make Tech Easier published an owner review of the original KingSmith WalkingPad A1 in November 2019, updated in January 2024.

The reviewer reported several practical observations:

• The treadmill was convenient to store beneath suitable furniture.

• The transport wheels made repositioning possible, although lifting one end was awkward.

• The manual mode maintained a selected speed.

• The automatic mode responded to the user’s position on the belt.

• The user considered the novice safety guide important.

• Stopping the treadmill reset the current session’s displayed statistics.

The reviewer also emphasized that users need to remain attentive when operating a walking pad without a fixed handrail.

These observations are useful because they address practical ownership rather than relying exclusively on specifications.

However, they represent an individual experience with an older unit. They do not establish the mechanical condition or performance of every A1 still available on the secondhand market.

Noise and cushioning

The manufacturer describes the A1 as a compact home-walking treadmill, but no sufficiently documented independent noise measurement was established for the exact original model.

It would therefore be misleading to assign it a precise decibel rating or claim that it is silent.

The same caution applies to cushioning. A multi-layer walking surface and shock-absorption materials are design characteristics, not proof of a particular reduction in joint impact.

Floor construction, belt condition, footwear, speed, and user weight can all affect the perceived walking experience.

Compatibility, sizing, and safety

The A1’s 47.2 x 16.3-inch walking surface is relatively compact compared with a full-size treadmill.

For ordinary indoor walking, that can be sufficient for some users. However, the available width is an important consideration for people with wider walking patterns or a tendency to drift sideways.

Taller users should also consider their natural stride length.

A walking surface can be advertised as suitable for home walking without necessarily accommodating every user’s preferred pace comfortably.

Weight capacity

The original A1’s weight-capacity discrepancy requires particular attention.

The current manufacturer comparison identifies 198 pounds, while the Canadian FAQ and available manual identify 220 pounds.

For a used machine, buyers should inspect:

1. The model identification label.

2. The maximum user-weight rating printed on the unit.

3. The original manual, if available.

4. Any seller documentation identifying the exact regional version.

Until the discrepancy is resolved for a particular unit, do not use 220 pounds as an assumed universal capacity.

Safety without a handrail

The original A1 does not include a fixed handrail or a safety key according to the manufacturer’s regional model comparison.

This is important because users have no conventional upright handhold when walking.

People who need additional physical support, have balance difficulties, or want to perform faster workouts should consider a model with a suitable handrail instead.

The manual also describes a child-lock function, which helps prevent unintended operation. A child lock is not equivalent to an emergency safety key.

Keep children and pets away from the running belt while the machine is operating. Start slowly, use stable footwear, and understand the selected operating mode before increasing speed.

Strengths and limitations

The original WalkingPad A1 is an interesting design, but its suitability depends heavily on the buyer’s expectations.

Pros

• Folding deck reduces storage length.

• Approximately 47-inch-long walking surface.

• Maximum speed around 3.75 mph.

• Pressure-sensing automatic speed control.

• Integrated LED display.

• Low-profile construction suitable for some home-office arrangements.

• Transport wheels assist with repositioning.

• No complicated assembly procedure is described in the model documentation.

Cons

• Original model is no longer listed in the U.S. manufacturer’s store.

• Brushed motor rather than the newer A1 Pro’s brushless motor.

• Maximum speed is limited to walking.

• No adjustable incline.

• No fixed handrail or safety key.

• The published weight-capacity figures conflict.

• App compatibility is inconsistent across regional sources.

• Approximately 60 pounds makes frequent lifting inconvenient.

• Used units may have limited warranty and replacement-part support.

The biggest strength is the folding design. The biggest weakness is that the original A1 is now an older product with less certain support and specifications than its successor.

Maintenance and ownership costs

The A1 requires basic maintenance to keep the running belt operating properly.

The available manual describes three main maintenance tasks:

Cleaning: Unplug the machine before cleaning. Wipe the walking surface and remove dust and debris from the motor-cover area.

Lubrication: The walking belt needs periodic lubrication to reduce friction. The manual recommends following the lubrication-kit instructions and adjusting maintenance frequency according to usage.

Belt alignment: A belt that moves away from the center or becomes loose may require adjustment using the supplied hex wrench.

These procedures are relatively straightforward, but maintenance history matters when buying a secondhand A1. A machine that has not been lubricated or whose belt has been poorly adjusted may require attention before normal use.

Warranty and returns

The original A1’s current U.S. warranty availability is not established.

WalkingPad’s current U.S. website advertises a one-year limited warranty for eligible direct purchases, but the original A1 is no longer listed as a current U.S. product. Buyers should not assume that the current policy covers an older machine purchased secondhand.

The official return policy applies to purchases made directly through WalkingPad.com. Purchases from other retailers or marketplaces are subject to the original seller’s terms.

The manufacturer’s current return policy also identifies return shipping charges for certain walking-pad models, but those rates should not be applied to the original A1 without confirmation.

For a used purchase, ask the seller about the original receipt, warranty status, remote control, power cord, operating history, and whether the machine has any belt or motor issues.

WalkingPad A1 vs A1 Pro: Which should you choose?

The A1 Pro is the most direct alternative because it was developed as an improved version of the original A1.

The two share a similar folded footprint and maximum walking speed, but the A1 Pro changes several important ownership characteristics.

The A1 Pro is the more logical choice for someone buying new because it has current manufacturer support, a brushless motor, and additional control options.

However, buyers must still check the capacity of the particular A1 Pro variant rather than assuming every version carries the same rating.

The original A1 may still make sense as a used purchase when its price, condition, and verified weight rating are appropriate. Its folding design and maximum speed remain useful for ordinary indoor walking.

Buy if / Skip if

Buy the original A1 if:

• You find a well-maintained used unit.

• Your primary activity is indoor walking.

• You have limited space and need a folding deck.

• The walking surface fits your stride.

• The unit’s actual weight capacity is sufficient.

• The remote, power cord, and folding mechanism are included and functional.

• You can confirm access to compatible maintenance parts.

Skip the original A1 if:

• You need a currently supported treadmill.

• You require more than its documented 3.75 mph maximum speed.

• You need a handrail or emergency safety key.

• Your weight is close to or above the confirmed capacity.

• You need reliable app-based workout tracking.

• You expect to move the machine frequently.

• The seller cannot demonstrate that the belt, motor, and controls work correctly.

For most new U.S. buyers, the A1 Pro is a more sensible starting point than searching for an older original A1.

FAQ
