Why the A1 Pro went out of stock — and why it is not coming back
The KingSmith WalkingPad A1 Pro was the market consensus pick from roughly 2023 through 2025. It combined a 47-inch belt, a proven brushless motor, and a $349–$499 price point that made it the default recommendation in almost every major buying guide, including ours.
In early 2026, global stock dried up. KingSmith.com lists it as sold out, Amazon shows no available units, and there is no public restock timeline. The likely explanation: KingSmith has transitioned its product lineup to the R-series and X21 as its flagship models. The A1 Pro served its purpose as the brand-builder; the R-series is the product KingSmith actually wants to sell at premium pricing. The R2 that headlined that lineup has since been discontinued too — KingSmith replaced it with the newer WalkingPad R3 Hybrid+, which is the premium pad we now recommend.
For buyers, this is mostly good news. The A1 Pro's successors are better machines. The P1 preserves the A1 Pro's core specs at a lower price. The R3 Hybrid+ surpasses it on every hardware dimension. And non-KingSmith options like the Z1 have closed the quality gap that once made the A1 Pro the obvious default.

WalkingPad R2 — the premium upgrade (now the R3 Hybrid+, $799)
Best for: A1 Pro owners who want the natural upgrade, not just a replacement.
Heads up: the WalkingPad R2 has been discontinued — KingSmith replaced it with the newer WalkingPad R3 Hybrid+ 2-in-1 Treadmill, which is the model we now recommend. It is the live, in-stock successor and carries forward everything that made the R2 the natural step up from the A1 Pro.
The R3 Hybrid+ is the walking pad the A1 Pro pointed toward. It comes from the same manufacturer, carries the same WalkingPad branding, and is built to a meaningfully higher standard — a newer listing backed by KingSmith's established R-series track record.
Where the A1 Pro had a 16.5-inch-wide belt, the R3 uses the same proven 17-inch-wide by 47-inch-long belt footprint as the R2 — the extra half-inch over the A1 Pro is noticeable for taller walkers or anyone with a wider natural stride, and the 47-inch length is identical to the A1 Pro's. The speed range is 0.5 to 7.5 mph: roughly 4 mph in under-desk mode with the height-adjustable handrail lowered, climbing to 7.5 mph with it raised to run — turning the R3 into a genuine 2-in-1 machine the walk-only A1 Pro cannot match. The frame is one-piece aluminum alloy — no plastic joining points that flex or crack under sustained use — and dual side handrails add stability when you pick up the pace. It carries a 265 lb weight capacity, pairs with the KS Fit app plus an LED display for steps, speed, time, and distance, ships fully assembled, and uses a double-fold design that stores upright.
At $799, the R3 costs about $300 more than the A1 Pro's last list price. That premium is real, but it buys a machine that will last longer, perform better, and serve users who have grown beyond walking pace. If your budget stretches to $799, this is the correct answer to "what should I get instead of the A1 Pro."
R3 Hybrid+ vs A1 Pro in brief: wider belt, same length, running capability, one-piece aluminum frame, dual side handrails, 265 lb capacity, KS Fit app, about $300 more.
KingSmith WalkingPad P1 — the like-for-like match ($349)
Best for: Buyers who want the closest possible A1 Pro experience at the lowest price.
The KingSmith P1 is the most direct A1 Pro replacement. Same brand, same brushless motor quality, same 47-inch belt length. Belt width is 15.75 inches — slightly narrower than the A1 Pro's 16.5 inches, which is the only real concession. At $349, it costs $150 less than the A1 Pro's last list price.
For most users, the 0.75-inch width difference is not meaningful. If you are under 5'10" or wear a shoe size below 12, the P1's belt is more than adequate. If you are tall or broad-framed and the A1 Pro's belt was already feeling slightly narrow, consider the Z1 or R3 Hybrid+ instead.
The P1 runs at up to 3.8 mph and operates in the same 42–48 dB range as the A1 Pro — quietly enough for video calls, comfortably below apartment noise thresholds. Like the A1 Pro, it folds flat for under-desk storage and slides under most beds when not in use.
P1 vs A1 Pro in brief: same brand and motor quality, same belt length, slightly narrower belt, $150 less, currently in stock.
WALKINGPAD Z1 — the quiet value pick ($299)
Best for: Buyers who want a belt wider than the A1 Pro's and do not need running capability.
The WALKINGPAD Z1 is a non-KingSmith alternative that actually beats the A1 Pro on its most important spec: belt size. The Z1's belt measures 17.3 inches wide and 47.2 inches long — wider than the A1 Pro's 16.5 inches and virtually the same length. It is rated below 40 dB at walking speeds, making it one of the quietest walking pads in our comparison at any price.
At $299, the Z1 is $200 less than the A1 Pro's last list price. That gap makes it hard to argue against for buyers who are primarily walking at desk pace and want the largest belt available under $400. The trade-off is brand recognition — WALKINGPAD is not the KingSmith/WalkingPad family, though it occupies the same quality tier in practical use.
For apartment dwellers who need quiet above all else, or for taller walkers who need every inch of belt width they can get, the Z1 is worth serious consideration. See our belt size guide to match your height to the right belt dimensions.
Z1 vs A1 Pro in brief: wider belt, same length, quieter (sub-40 dB), $200 less, not a KingSmith product.
DeerRun 4-in-1 — the capacity pick ($239)
Best for: Heavier users (up to 300 lbs) and buyers who want incline capability.
The DeerRun 4-in-1 serves a different use case than the A1 Pro, but it fills an important gap in the lineup. Its 300-pound weight capacity is the highest of any compact walking pad in our catalog — the A1 Pro's 220-pound limit left a large group of potential buyers underserved.
At $239, the DeerRun includes variable incline (controlled via app), a 16.53-inch-wide belt, and running capability up to 7.5 mph. It is not as polished as the KingSmith products, and the 4-in-1 label overpromises slightly — but the core machine is solid, the motor is reliable, and the weight rating is genuine.
If you were looking at the A1 Pro because it was the default recommendation but your body weight is over 200 pounds, the DeerRun is a better fit than any of the KingSmith alternatives. Read our complete guide for heavier walkers for a full breakdown by weight range.
DeerRun vs A1 Pro in brief: 300 lb capacity vs 220 lb, includes incline and running, belt slightly narrower (16.53"), $260 less.
GoPlus 2-in-1 — the budget option ($199)
Best for: First-time buyers and anyone who needs running capability under $200.
The GoPlus 2-in-1 is the simplest recommendation at the lowest price point. At $199, it delivers 7.5 mph running with its handrail raised, 4 mph walking without, a 16-inch belt, and a motor that has proven reliable across thousands of verified Amazon reviews. It is not as quiet or as premium-feeling as the KingSmith products, but it performs its core function well.
For buyers who were considering the A1 Pro primarily because it appeared in every buying guide — rather than because they specifically needed a KingSmith pad — the GoPlus often does the job at $300 less. If you walk at desk speed for 30–90 minutes per day and do not need a premium brand, the GoPlus is the honest budget answer.
The GoPlus is also the strongest entry in our best walking pads under $300 guide and our 2-in-1 walking pad roundup.
GoPlus vs A1 Pro in brief: $300 less, adds running to 7.5 mph, slightly narrower belt (16"), louder at walking speeds (~50 dB).

How to Compare Current Prices
An A1 Pro replacement is only a good buy if it preserves the features you cared about. The P1 and Z1 focus on desk walking and long belts; the R3 Hybrid+ adds running capability at a much higher price.

What made the A1 Pro popular — and what to look for instead
Understanding why the A1 Pro dominated buying guides for two years helps you evaluate its replacements honestly.
Belt size. The A1 Pro's 47-inch belt was long enough for most adult walkers to stride naturally. Many competing pads in its price range used 40–43-inch belts, which feel cramped above 3 mph. Any pad on this list that matches or exceeds 47 inches on length is keeping pace with the A1 Pro on that dimension. See our belt size guide for a full breakdown by height.
Quiet operation. The A1 Pro was quiet enough for video calls — roughly 45–50 dB at walking pace. The Z1 beats it (sub-40 dB). The P1 matches it, and the R3 Hybrid+ uses a quiet brushless motor in the same tier. The GoPlus and DeerRun run slightly louder at 48–55 dB.
Under-desk compatibility. The A1 Pro had no fixed handrail, so it slid under a standing desk without adjustment. The P1 and Z1 share this form factor, and the R3 Hybrid+ lowers its height-adjustable handrail to walk under a desk, then raises it to run. The GoPlus and DeerRun include handlebars that fold flat for storage but add height when deployed for running.
Brand trust. KingSmith's reputation is the main reason the A1 Pro commanded a premium. The P1 and the R3 Hybrid+ carry the same brand assurance — the R3 is a newer listing, but it is backed by KingSmith's established R-series track record. The Z1 and GoPlus have strong Amazon review records — 4.2 stars on 2,000+ reviews for the Z1 — but lack the brand recognition.
Our verdict
The WalkingPad A1 Pro built its reputation fairly. But it is gone, and the five pads above are the honest alternatives for every buyer type it served.
If you want to stay in the KingSmith family: the P1 replaces it on price and the R3 Hybrid+ upgrades it on specs (it is the in-stock successor to the discontinued R2). If you want the widest belt at the best value: the Z1 wins. If weight capacity is your constraint: the DeerRun is the only option that genuinely covers heavier users. If you just need a working pad at the lowest price: the GoPlus delivers.
All five are in stock. The A1 Pro is not.
