WalkingPad Z1 Review: Folding Under-Desk Treadmill Specs

Verdict in brief

The WalkingPad Z1 is KingSmith's most affordable pad with a deck that folds in half. Walkingpad.com lists a brushless motor, a speed range of 1 to 4 mph, a 242 lb weight limit and a 47.6 by 15.7-inch belt. It weighs 51 lb, stands 4.1 inches tall when open and folds to 31.8 by 22 by 5.4 inches. It sits in the mid-range price tier, below the C2 and well below the A1 Pro.

On paper, it matches or beats the better-known WalkingPad C2 on belt length, weight limit, top speed and machine weight. What you give up is the C2's FootSense automatic speed mode, which KingSmith's US pages do not list for the Z1, and some certainty about the motor, because KingSmith's two sites quote very different horsepower figures. For a desk walker under 242 lb who wants a pad that folds away every evening, it is the easiest KingSmith to recommend on value. If you want a handle, read the Z1R section below before you order.

Key specs

Figures are from walkingpad.com unless noted. KingSmith runs two storefronts, walkingpad.com and kingsmith.com, and they do not agree on every number for the Z1.

Note: the motor figure is the biggest disagreement. A 2.25 HP rating and a 0.75 HP rating cannot both describe the same motor in the same way; one may be a peak figure and the other a continuous one, but neither site says which. We therefore do not rank the Z1 on motor power. A UK review site, hometreadmill.co.uk (May 2026), describes a Z1 with FootSense, a 1.25 HP motor, a 3.7 mph top speed and a narrower 41.5 cm belt. Those figures do not match the US pages, which suggests the UK and US versions differ. Go by the listing you are buying from.

Who it suits

• Small homes that need the pad gone every evening. Open, the Z1 covers about 56.1 by 22 inches, roughly 8.6 square feet. Folded, it covers about 31.8 by 22 inches, roughly 4.9 square feet, with a 5.4-inch height. That fits many closets and some under-bed gaps.
• Desks that do not rise very high. At 4.1 inches tall when open, the Z1 adds little height under a standing desk. If your desk is already near its top setting when you stand, every inch counts.
• Buyers who want the longest belt for the money. A 47.6-inch belt is one of the longest in KingSmith's walking range and longer than most budget flat pads. See our walking pads for tall people if stride length is a concern.
• Walkers up to about 220 lb who want margin. The rating is 242 lb. We suggest staying comfortably under a pad's limit; our weight limit guide explains why.

What stands out

Fold-in-half at a lower price tier

The Z1 uses the same idea as the C2: a hinge across the middle so the deck halves in length. It is one reason the Z1 appears in our best foldable walking pads and best compact walking pads guides. At 51 lb it is also 4 lb lighter than the C2, which helps if you fold and roll it away daily. It has transport wheels.

A slim open profile

KingSmith lists the open height as 4.1 inches, and kingsmith.com adds a 2.64-inch deck height, which likely describes the walking surface rather than the tallest point of the frame. Either way, it is low for a pad with a hinge in the middle.

A little faster than the C2

The top speed is 4 mph against the C2's 3.7 mph. That is still walking pace, but it gives a brisk walker a small extra margin. At 4 mph, 30 minutes covers 2 miles.

App, Apple Watch and Kinomap

The Z1 pairs with KingSmith's KS Fit app, works with an Apple Watch through the app, and walkingpad.com says it connects over Bluetooth to Kinomap for virtual walks. A remote is included.

Drawbacks

• Motor figures conflict. 0.75 HP, 1.25 HP and 2.25 HP all appear in sources. For walking speeds under 4 mph this matters less than it would on a running treadmill, but it makes the Z1 hard to compare on power.
• No FootSense on the US pages. You control speed with the remote or app. Some buyers will prefer that; others choose KingSmith for the automatic mode.
• No handle and no incline. It is a flat walking pad. For a rail, see the Z1R below or our walking pads with a handle.
• Belt width of 15.7 inches. That is fine for walking in a straight line, but narrower than the 16.5-inch belts on the P1 and A1 Pro.
• Stock varies by storefront. kingsmith.com lists the Z1 as sold out, while walkingpad.com and Amazon carry it. Buy from a seller that shows it in stock.

The WalkingPad Z1R: the same pad with a handrail

The Z1R shares the Z1's 47.6 by 15.7-inch belt and 242 lb limit, and adds a removable handrail. Walkingpad.com lists a 2.25 HP brushless motor, a higher 1 to 5 mph speed range, EVA and PET cushioning, the KS Fit app, a remote, Kinomap support and the same 1-year warranty with an optional extension. It weighs 57.7 lb.

The key difference is storage. With the rail up, the Z1R measures 55.9 by 23.2 by 37.9 inches. With the rail folded down, it is 49.2 by 23.2 by 5.5 inches. That 49.2-inch folded length shows the deck itself does not fold in half; only the handrail folds flat. So the Z1R needs a flat space about 17 inches longer than the folded Z1. It slides under a bed or sofa more easily than it fits in a closet.

Choose the Z1R if balance or confidence matters more than a small folded size, for example for older walkers or anyone new to walking pads. Choose the Z1 if closet storage is the priority. Our best walking pad with handle guide compares the Z1R with other railed pads.

Who should skip it

Skip the Z1 if you weigh more than 242 lb, if you want to jog or use incline, or if you specifically want KingSmith's FootSense automatic mode on a US model. Also skip it if you want to compare motors on paper before you buy, since the published figures do not agree. Heavier walkers who still want a fold-in-half pad should look at the 300 lb version of the WalkingPad A1 Pro.

How it compares

The closest rivals are KingSmith's own WalkingPad C2, which folds the same way, and the WalkingPad P1, an older KingSmith pad that also folds in half and has a wider belt. The Z1R is included for reference.

Z1 vs WalkingPad C2. The two fold to almost the same size. The Z1 wins on belt length (47.6 vs 47.2 inches), weight limit (242 vs 220 lb), top speed (4 vs 3.7 mph) and machine weight (51 vs 55 lb), and it sits in a lower price band. The C2 adds FootSense, a published 1 HP motor figure and a 0.5 mph minimum speed. See our WalkingPad C2 review.

Z1 vs WalkingPad P1. The P1 also folds in half, to 32.5 by 21.5 by 5 in, and KingSmith lists a wider 47.24 by 16.5 in belt, 0.3 to 3.75 mph, FootSense automatic speed control and app support. It is heavier at 62 lb, uses an older brushed motor and is rated for 220 lb, against 242 lb for the Z1. Choose the P1 for belt width and the Z1 for the lighter frame and higher rating. The P1 was in stock on Amazon when we checked on October 30, 2026. We compared the Z1 with the FlexiSpot Fold X here before, but its Amazon listing returned a 404 that day; our FlexiSpot walking pad review covers FlexiSpot's other pads.

Setup, maintenance and warranty

Setup. The Z1 arrives fully assembled. Unfold it on a hard, level floor, make sure the hinge sits flat and locked, and pair the remote and app. On carpet, read our walking pad on carpet guide.

Maintenance. Lubricate the belt on the schedule in the Z1 manual with the lubricant KingSmith specifies, and check belt tracking now and then. Our guides to lubricating a walking pad and fixing a belt that is off center cover the basics. Always stop the belt and unplug the pad before folding it.

Warranty and returns. Walkingpad.com lists a 1-year warranty with an optional extension and 30-day returns on the Z1 and Z1R. WalkingPad's FAQ says the one-year limited warranty covers products bought directly from walkingpad.com. On Amazon, check the seller's warranty terms. We found no CPSC recall for WalkingPad or KingSmith products when we checked in September 2026.

How we researched this review

We compared the Z1 and Z1R pages on walkingpad.com, the Z1 page on kingsmith.com, WalkingPad's FAQ, the Amazon listing and the hometreadmill.co.uk review, and we checked the CPSC recall database. We did not test the Z1 or Z1R in person. Where sources disagree, we show both figures and name the source. More on our method is on the how we research page, and the full brand line-up is in our KingSmith WalkingPad round-up.
