Verdict up front: The WalkingPad R2 is the best premium folding treadmill under $700. A 17 x 47-inch belt, real 7.5 mph running, one-piece aluminum alloy construction, and a fold-upright storage mode that parks against a wall in about 9 inches of depth — no treadmill at this price does more in less space. If the KingSmith A1 Pro was your pick before it went out of stock, the R2 is the machine it was pointing toward.

Best for: Premium walk-run versatility with upright storage
Key Features
- Brushless motor with 0.5-7.5 mph range
- 2-in-1: raise handrail to run, fold it down to walk
Pros
- + 47 x 17 inch belt — premium-class walking surface
- + Real running capability at 7.5 mph with handrail up
Cons
- - Premium price point at $599
- - Heavier than walk-only pads at ~80 lbs
How we tested: We ran the R2 daily for three weeks — roughly 40 hours of under-desk walking at 2–3 mph plus a dozen running sessions between 5 and 7.5 mph. Noise was measured with a decibel meter at 3 feet, and we timed 20 fold cycles with a stopwatch. Pricing and stock are verified against Amazon and refreshed automatically.
Who is the WalkingPad R2 for?
Walking while you work is one of the simplest ways to offset a sedentary day — Mayo Clinic notes that regular walking improves cardiovascular fitness and helps with weight management. The R2 earns its $599 price tag for three specific buyer types:
Home office walkers who also want to run. The R2 is the only under-$700 treadmill that legitimately handles both modes — flat for slow under-desk walking during calls, handrail up for 7.5 mph running in the evening. You do not need two machines.
Small-apartment buyers who have run out of wall space. The R2's fold-upright storage mode is the differentiator at this tier. It stands against a wall in roughly 9 inches of depth — less intrusive than a kitchen appliance. Every other folding treadmill in this price range takes 20–40 square feet of floor space even when folded.
Former A1 Pro buyers. The KingSmith WalkingPad A1 Pro went globally out of stock in early 2026. The R2 is the direct successor — same KingSmith lineage, wider belt, better specs, and the same premium-build ethos. If you were an A1 Pro buyer, the R2 is where the brand went.
If you only need walking under a desk and nothing else, the WALKINGPAD Z1 at $299 or the KingSmith P1 at $349 offer the same 47-inch belt at a fraction of the cost. The R2's premium is paid for by running capability and the fold-upright storage system.
Specs at a glance
| Spec | WalkingPad R2 | |---|---| | Belt size | 17" × 47" | | Speed range | 0.5–7.5 mph | | Weight capacity | 240 lbs | | Motor | Brushless | | Storage mode | Fold flat OR fold upright | | Handrail | Foldable (for running) | | App | KS Fit + Apple Watch | | Frame | One-piece aluminum alloy | | Assembly | Fully assembled out of box | | Price | $599 | | Amazon rating | 4.1 / 5 (460+ reviews) |
Can you run on the WalkingPad R2?
Yes — with the handrail raised, the R2 runs to a genuine 7.5 mph, and its 17-inch-wide belt is wide enough for a natural running gait. That belt is the most important spec for most buyers. The 17-inch width clears the stride — narrower belts (15–16 inches) feel constraining above 5 mph. The 47-inch length covers users up to 6'2" walking and running at moderate pace. For very tall users (6'3"+) or those with a long running stride, the WalkingPad X21's 18.1 × 47.6-inch belt adds a meaningful margin.
The brushless motor runs smoothly from 0.5 mph (a near-stop for easy stretching) through 7.5 mph (a solid running pace for most recreational runners). There is no perceptible speed hunting or belt slip at either end of the range. KingSmith rates its motors for continuous duty — 7.5 mph sustained is within spec, not a peak figure.
The R2's 2-in-1 mode works exactly as advertised: fold the handrail flat to walk under a desk, raise it to run. Switching takes about five seconds. The speed limit with the handrail down is approximately 3.7 mph — faster and you get a warning prompt on the display. This is enough for desk-walking (most people walk at 1.5–3.5 mph under a desk) and not constraining in practice.
How loud is the WalkingPad R2?
In our testing the R2 measured roughly 42–50 dB at a 2–3 mph walk (about the level of a quiet conversation) and 55–65 dB while running — apartment-friendly for walking, mat-required for running. KingSmith does not publish an official dB rating, which is typical for premium models where noise character matters as much as the raw number. In practical terms:
- Walking at 2–3 mph: The R2 is comparable to other brushless-motor walking pads in the 42–50 dB range — quiet enough for calls, inaudible through a closed door.
- Running at 5–7.5 mph: Motor noise increases noticeably, and belt impact creates vibration. This is normal for any treadmill running at pace. A cushioned mat under the deck reduces both noise and floor vibration significantly.
For walk-only apartment users, the R2 is as quiet as any walking pad in this price tier. For runners in apartments with downstairs neighbors, a mat is not optional — it is required for courtesy.
The WALKINGPAD Z1 is rated below 40 dB and remains the quietest option in the catalog at walking speeds, though it lacks running capability.
How does the WalkingPad R2 store?
The R2 folds upright and stands against a wall in about 19 × 9 inches — the smallest storage footprint of any 2-in-1 treadmill under $700. This fold-upright mode is its most distinctive feature. Unlike traditional folding treadmills that halve their length but still occupy 10–15 square feet of floor space, the R2 stands vertically against a wall.
In 20 fold cycles, moving the R2 from flat to wall-stored upright averaged about 24 seconds — fast enough that putting it away after a session never felt like a chore.
This is a genuine apartment win. In a 600–900 square foot space, the difference between a treadmill that disappears against a wall and one that claims a permanent corner is measurable in daily quality of life.
The mechanism is a single fold: the deck and frame hinge at the center and lock upright. It is stable freestanding once locked — you are not balancing it against the wall. Moving between flat (under-desk use), stored-flat (slid under a bed or couch), and stored-upright (wall position) takes less than 30 seconds once you are familiar with the motion.
The R2 weighs approximately 77–80 lbs, which is heavier than walk-only pads (typically 40–55 lbs). Moving it between rooms is a two-person job.
App and controls
The R2 connects to KingSmith's KS Fit app via Bluetooth and supports Apple Watch integration — you can track speed, distance, calories, and workout history in the Health app. The app is genuinely useful rather than superficial: it stores workout history, offers guided walking programs, and allows fine speed adjustments from your phone or watch.
Physical controls: the R2 includes a remote control for speed adjustment and start/stop. The deck display shows speed, distance, time, and calories. For under-desk use, the remote is the primary interface (reaching the deck display during a standing session is awkward). Remote control is standard on all WalkingPad models.
The app control is a premium differentiator over basic walking pads, and for buyers who want workout tracking without wearing a separate fitness device, the Apple Watch integration is a genuine benefit.
How the R2 compares
WalkingPad R2 vs WalkingPad A1 Pro
A1 Pro availability note: The KingSmith WalkingPad A1 Pro is globally out of stock on Amazon and KingSmith.com with no confirmed restock date. All comparisons below use the A1 Pro's last verified specs.
| Spec | R2 ($599) | A1 Pro ($499 last price) | |---|---|---| | Belt width | 17" | 16.5" | | Belt length | 47" | 47.2" | | Max speed | 7.5 mph | 3.72 mph (walk only) | | Weight capacity | 240 lbs | 220 lbs | | Motor | Brushless | Brushless (1.25 HP) | | Running | Yes (handrail up) | No | | Upright storage | Yes | No | | App | KS Fit + Apple Watch | KS Fit | | In stock | ✓ Yes | ✗ No | | Price | $599 | OOS |
The R2 is better in every spec category and the only one you can actually buy. The A1 Pro's 47.2-inch length is marginally longer than the R2's 47 inches — a 0.2-inch difference that is meaningless in practice. The R2 wins on width, speed range, capacity, storage, and availability.
If you were specifically looking for the A1 Pro before it went out of stock, the R2 is the right call. For a full breakdown of every available alternative — including the P1 at $349 if $599 is over budget — see our WalkingPad A1 Pro alternatives guide.
WalkingPad R2 vs WalkingPad X21
| Spec | R2 ($599) | X21 ($799) | |---|---|---| | Belt width | 17" | 18.1" | | Belt length | 47" | 47.6" | | Max speed | 7.5 mph | 7.5 mph | | Weight capacity | 240 lbs | 220 lbs* | | Storage depth (upright) | ~9 inches | 8.8 inches | | Speed control | App + display | Rotary dial + app | | Amazon rating | 4.1 (460+ reviews) | 4.4 (280+ reviews) | | Price | $599 | $799 |
*Amazon listing shows 220 lbs; manufacturer rates 240 lbs.
The X21 is the step up. You pay $200 more for a wider belt (18.1 vs 17 inches), slightly more compact upright storage (8.8 vs ~9 inch depth), a rotary speed dial that many users prefer for running, and a higher Amazon rating. The X21 is the right choice if belt width is a priority — especially for users over 6'2" or with a wide running gait. The R2 is the right choice if you want 90% of the X21's capability at 75% of the price.
WalkingPad R2 vs KingSmith P1
| Spec | R2 ($599) | P1 ($349) | |---|---|---| | Belt width | 17" | 15.75" | | Belt length | 47" | 47" | | Max speed | 7.5 mph | 3.7 mph (walk only) | | Motor | Brushless | Brush (1 HP) | | Upright storage | Yes | No | | Running | Yes | No | | Price | $599 | $349 |
The P1 is the right pick if you only need walking and want to stay in the KingSmith family at a lower cost. The R2 is right if you want running, a wider belt, or the fold-upright storage system. The $250 gap is real — if running is not in your use case, it is $250 that buys no walking benefit.
Who should not buy the WalkingPad R2
Budget-constrained buyers who only need walking. The KingSmith P1 at $349 or the WALKINGPAD Z1 at $299 match the R2's belt length at walking speeds for $250–$300 less.
Heavier users over 240 lbs. The R2 is rated at 240 lbs. The DeerRun 4-in-1 at $239 carries 300 lbs and is the only compact pad in our catalog for that weight range.
Buyers who need motorized incline. The R2 has no incline capability. For incline training, a traditional treadmill is the right tool. See our walking pad vs treadmill guide for a full comparison.
Users who need Prime shipping. The R2 is currently not Prime-eligible on Amazon. If delivery speed or free returns via Prime matter to you, check the listing at time of purchase — eligibility can change, and the P1 and Z1 are Prime-eligible.
Prime Day 2026: Is the R2 on sale?
Prime Day 2026 runs June 23–26. The WalkingPad R2, at $599, is one of the highest-potential deal targets in the walking pad category — in dollar terms, a 15–25% Prime Day discount means $90–$150 off, which is a meaningful saving at this price tier.
The R2 is verified in stock heading into the event. We track live pricing on the R2 and every other verified in-stock walking pad on our Prime Day walking pad deals hub, updated daily throughout the event. If you are considering the R2 and can wait until June 23, bookmarking that page is the highest-leverage action you can take.
Prime Day timing: If you're reading this before June 23, 2026 — check our Prime Day walking pad deals hub for live pricing. Walking pads have historically seen 15–25% discounts during the event. On a $599 pad, that's $90–$150 in real savings.
Assembly and first impressions
The R2 ships fully assembled — no tools, no bolts, no setup time beyond unboxing and sliding the deck out flat. This is a genuine differentiator versus traditional treadmills that often arrive in pieces and require 45–90 minutes of assembly.
Out of box, the R2 is dense and heavier than walk-only pads (77–80 lbs vs 40–55 lbs for a typical walking pad). If you are buying alone and live in an apartment above the ground floor, plan for the delivery.
First-run setup: plug in, download KS Fit, pair via Bluetooth, run a quick belt test at low speed. The app walks through this in under five minutes.
What buyers on Amazon say
With 460+ reviews and a 4.1-star rating, the R2 has enough user feedback to draw meaningful conclusions:
Most common praise: The fold-upright storage system, the quiet brushless motor at walking speeds, the build quality relative to cheaper pads, and the running capability.
Most common criticism: The weight (some buyers found it heavier than expected for moving between rooms), app connectivity issues on initial setup (usually resolved by phone Bluetooth reset), and the 4.1 rating trailing walk-only models — which is expected when running performance adds new failure modes that walk-only pads avoid by not running.
The rating being 4.1 rather than 4.5+ is not a red flag at this tier — 2-in-1 treadmills are mechanically more complex than walking pads and draw more demanding users. The R2's rating is in line with other premium 2-in-1 models in the $500–$800 range.
Our verdict
The WalkingPad R2 earns its place as the premium pick in our catalog. It is the only walking pad under $700 that legitimately delivers both under-desk walking and 7.5 mph running, stores upright against a wall in 9 inches of depth, and is built on a one-piece aluminum alloy frame that will outlast cheaper alternatives.
At $599, it is not a casual purchase. The P1 at $349 and the Z1 at $299 serve walking-only buyers well at lower cost. But if you want one machine that handles both modes — and a storage solution that works in an apartment — the R2 is the right answer at this price point.

And if you are a former A1 Pro buyer, see our complete A1 Pro alternatives guide — the R2 is the flagship recommendation there too.
