The WalkingPad X21 Double Folding Treadmill is a premium home treadmill designed for space-saving fitness. With its patented double folding system, quiet brushless motor, spacious running belt, and app connectivity, it delivers a gym-quality workout in a compact design. Perfect for small flats, home offices, or modern living spaces, the X21 offers walking, jogging, and running with effortless setup and storage.
Double Folding System – Save Space Instantly
Unlike traditional treadmills, the X21 folds in two steps to just 0.16㎡ upright space with a compact 100cm height. A lift-lock mechanism prevents the deck from falling over, ensuring safe storage. This makes it ideal for city flats or homes where space is limited.
Spacious, Low-Profile Running Deck
The 121 x 46cm running area provides enough room for both walking and running. With a low 9.6cm deck height, it’s safer to step on and reduces the risk of tripping. Built with hard-wearing PET and EVA shock-absorbing materials, the running board protects knees and joints.
Rotational Speed Control & Speed Range
The treadmill offers a 1–12 km/h speed range, adjustable in 0.1 km/h intervals for precise training. The rotary knob on the handlebar makes speed adjustment quick and intuitive. A 918W / 1HP brushless motor ensures durability and quiet performance, even during late-night workouts.
HD LED Display with Integrated Handlebar
The integrated LED display in the handlebar shows speed, time, distance, and calories in real time. It also includes a phone/tablet holder, so you can stream shows, follow workouts, or join virtual runs while exercising.
Smart App Connectivity
Connect the X21 to the KS Fit app (iOS/Google Play) to:
Record workouts and progress
Set start speed and preferences
Activate a child lock for safety
Review performance data over time
The treadmill also includes an emergency stop cable for added security.
