WalkingPad
WalkingPad X21 Double-Fold Folding Treadmill
Quick verdict
Best for: Joggers and runners who want a folding machine that stores upright in a slim footprint and need a fast walking-to-running range, and who do not need under-desk use.
- Buy if a double-fold machine that stores upright, runs to 7.5 mph, and supports a 240-pound user fits your room and you do not need under-desk walking.
- Skip if you need a remote, an adjustable handrail, an under-desk mode, an incline, a published warranty, or a lighter machine to move.

Editorial assessment
Who this product is for
The WalkingPad X21 is an 81-pound double-fold treadmill that runs to 7.5 mph and stores vertically in a published 39.6-by-27.9-by-8.8-inch envelope. It documents no under-desk mode, no incline, and no warranty.
By HomeGymPicker Editorial Team
Main advantages
WalkingPad documents a 1-7.5 mph range, a 47.6-by-18.1-inch running area, a 240-pound capacity, a 3.75 HP brushless motor, an 81-pound net weight, a 39.6-by-27.9-by-8.8-inch folded size, and a 55.8-by-27.9-by-41.4-inch unfolded body. The signature vertical fold stores the unit standing against a wall, connectivity lists the KS Fit app, Bluetooth, NFC, and Apple Watch, and a SpeedDial dial display replaces a conventional console.
Main limitations
The unit has no remote, the handrail is not adjustable, and the manufacturer documents walking, jogging, and running over the 1-7.5 mph range but no under-desk mode, so under-desk use is not recorded. With incline and warranty both unpublished, neither can be recorded. At 81 pounds the deck is heavy to reposition, and the folded height of 8.8 inches needs clearance in the standing stance.
Space, fit, and setup
Fold-away and upright storage are both recorded against the published 39.6-by-27.9-by-8.8-inch folded size, which stores standing against a wall or in a corner. Measure the standing height and the wall clearance, and keep a full running lane in front of the deck.
Fit, setup, and ownership cautions
Confirm the warranty directly, since none is published. Because there is no remote or adjustable handrail, plan every control action around the SpeedDial and app, and read the 3.75 HP figure as a claim rather than a continuous rating.
Research basis
Built from the exact WalkingPad X21 manufacturer page, recording the walk/jog/run modes and the vertical-fold geometry, and holding incline and warranty unknown. The profile is specification-based; no unit was assembled, folded, or run.
