Sure, it’s just a treadmill, but wait until you see its secret trick. Dubbed the world’s first treadmill with Double-fold technology, the King-Smith WalkingPad X21 is a full-sized treadmill that can fold away in an upright position. Collapsing into half the size, renters and small apartment owners will love the space-saving functionality of the WalkingPad X21, and that’s before we jump into its other incredible features. There’s a hidden LED digital display screen with an industrial aesthetic design and a one-touch operation panel on the handrail for seamless operation and control mid-stride. Android lovers will also love the X21 thanks to the NFC pairing for direct access to this high-tech treadmill. As for everyone else, the KS Fit app displays your time, speed, steps, and calories burned, allowing you to keep track of your workout history. Complimented by a detachable phone holder and an integrated luxury frame with a black spray paint finish, it’s no wonder it won the German Red Dot Award and the IF Design Award!
