WalkingPad Z1 Review: How Does It Compare With the C2 & A1 Pro?

Among these WalkingPad models with confirmed current machine weights, the Z1 is the lightest. It's 4 lb lighter than the C2, 12 lb lighter than the A1 Pro and 30 lb lighter than the X21.

That doesn't mean everyone will find it easy to carry — 51 lb is still heavy. WalkingPad's Z1 page says it has transport wheels for rolling it across the floor.

Unfolded: 56.1 × 22 × 4.1 in. Folded: 31.8 × 22 × 5.4 in.

Folding cuts the storage length from 56.1 in to 31.8 in, while the width stays at 22 in.

The Z1 is slightly shorter when folded, the C2 is narrower, and the A1 Pro is slightly thinner. These are small differences.

WalkingPad suggests sliding the folded Z1 under a bed or sofa, but that depends on your actual clearance, so measure first — we can't guarantee a fit. We don't recommend standing it upright unless WalkingPad's current manual explicitly allows it for the Z1.

These features are relevant to under-desk use:

• No permanent upright treadmill console
• 4.1-inch unfolded height
• 1–4 mph speed range
• Remote control
• KS Fit compatibility
• Folding format

Whether it works with your desk depends on the desk's height adjustment, your height, your footwear, the treadmill's height and your floor space. See our best under-desk walking pads for alternatives.

Minimum 1 mph, maximum 4 mph. The Z1 is intended mainly for walking.

If you want faster workouts, the WalkingPad X21 serves a different use case. See walking pad vs treadmill.

The Z1 has the longest published walking area of these three, by a small amount. The A1 Pro has the widest. Differences of fractions of an inch won't decide stride comfort on their own, and we can't say any of these suits every height.

WalkingPad currently lists 242 lb.

That's 22 lb more published capacity than the C2, but well below the current U.S. A1 Pro configuration. WalkingPad's A1 Pro page also lists a 230-lb option, so the A1 Pro review explains which version carries 300 lb.

WalkingPad currently lists a 2.25 HP brushless motor.

Horsepower alone doesn't tell you whether a machine is quieter, smoother, safer or more durable, so we don't draw those conclusions. The Z1's published top speed stays at 4 mph either way.

WalkingPad lists two speed-adjustment methods for the Z1: the handheld remote and the KS Fit app.

The Z1 page also notes Apple Watch pairing through the KS Fit app on an iPhone. Beyond that, app features can depend on the model and app version, so check the current app listing for anything specific you need.

What sets the Z1 apart from a basic flat walking pad:

• Folding deck with published folded dimensions
• KS Fit compatibility
• Handheld remote
• 51-lb published machine weight
• The WalkingPad/KingSmith ecosystem

If you have permanent floor space and only need basic walking, you may not need a folding deck or a connected app.

Technically, yes — it's a compact walking treadmill. But its design and 4-mph maximum set it apart from conventional upright running treadmills.

Not every treadmill has all of those features. See walking pad vs treadmill.

Walking Counts reviewed current manufacturer-published information: speed, walking-area dimensions, machine dimensions, folded dimensions, user capacity, machine weight, motor, control methods, app support, folding design and intended use.

This is a research-based review. Walking Counts has not claimed hands-on testing of the WalkingPad Z1.
