I am absolutely thrilled with the WalkingPad X21! As someone who highly values a clean, uncluttered living space and straightforward maintenance, this machine hits the absolute jackpot. My favorite feature by far is the innovative double-fold design. Unlike standard, bulky treadmills that become permanent dust-magnets on your floor, the X21 folds completely flat and stands upright securely. This makes it incredibly easy to roll out of the way so I can deeply sweep, vacuum, and clean my floors without wrestling with a heavy piece of machinery. Another massive win is the app integration. Through the app settings, you can completely turn off the operating chime so the machine is totally silent. This is perfect for my schedule because it means I can hop on for a walk anytime—day or night—without a loud beep waking anyone else up in the house. The build quality is rock-solid, the display controls are sleek and minimalist, and it operates beautifully. If you want a high-performance walking pad that respects your home's footprint and makes keeping your space pristine effortless, this is the one to get. Highly recommended!

Excellent treadmill! Solid construction and is exactly as advertised. The folding mechanism is excellent, the set-up is WalkingPad X214 and highly recommend it to anyone looking for a quality, space-saving treadmill.

A huge upgrade from the P1 I had before, this is fast and compact, with plenty of room for jogging on.

Great quality; I’m using it almost daily. Love it! Fan of the handle bars especially when walking very fast.

Treadmill can run up to 8 or 8.5mph can be checked-in oversize baggage if needed for travel. Has tiny wheels to pull around short distance, no incline options, has 2 handle bars that can be tucked while using if not needed. It works on/off, pause and clear to zero with bluetooth installed can sync for history of usage. Great for recovery to grow with patient. Under 100 lbs and size once folded of extra large suitcase or extra large duffle bag. Has quick stop. Shipping Box was 10lbs. Once unboxed was able to use wheels, nothing to put together just clean space and unfold twice, plug in and turn on. Convenient and functional worth the money for ease and travel once folded. I did not find any other treadmill that run this and foldable. December 2025 review paid $1000 for treadmill and it is worth that money to have ease of transport in car, is high priority for rehabilitation. It can grow with person as strength builds in legs for running. Long belt and average width stance it is not compact it is 2 folds, the belt folds unfolded normal belt length. Second fold is under control panel measured 18 inch belt, 9 inch wide thick once folded, height is 41 inches tall to include knob manual speed control, to fit in suitcase width is 18 belt side railing total is 30 inch width. X large suitcase for ease of pulling around for transport.

This is our second folding treadmill from this company. The first had an error code right out of the box and we had to pack it up and return after spending lots of time with unhelpful customer service. Assuming that one was just a lemon, we tried this model. It worked great for two workouts but is now giving a FOLD error. This one will also be making its way back to Sam's for a return. Unbelievably frustrating.
