The Definitive KingSmith WalkingPad X21 Double-Fold Treadmill for Elite Home Cardio
Our KingSmith WalkingPad X21 Double-Fold Treadmill is the definitive solution for those looking to accelerate their fitness goals while preserving their home’s aesthetic. Whether you are a busy professional walking during meetings or a runner performing a high-intensity 12km/h session, this machine adapts to your lifestyle. In addition to its sleek industrial design, the X21 features an all-aluminium alloy frame; as a result, it provides the stability and durability of a gym-grade machine in a lightweight, portable package.
Moreover, the user experience is enhanced by a concealed LED digital display. Specifically, the screen remains invisible while the treadmill is at rest but provides high-contrast feedback on Time, Speed, Distance, and Calories once powered up. Notably, the treadmill includes a four-layer professional running belt; thereby simulating a natural “road feel” while providing superior shock absorption to protect your joints.
The portable machine utilizes an innovative folding technique, allowing for a double fold.
The X21 foldable treadmill now achieves both 90° and 180° folding, further highlighting its sleek design and unique technological advancements.

One Handrail To Control Your Treadmill
The X21 introduces an operation panel on the armrest, offering enhanced control. Moreover, it provides a speed range of 0.5 to 12 km/h, allowing real-time adjustments to match your running pace.

Industrial Aesthetic Design With A Hidden LED Digital Display
The X21 features an integrated panel display. As a result, while at rest, its sleek surface stands out, but once powered up, the LED digital display showcases various data.

Superior Looks, Exceptional Intellect
The X21 boasts an all-aluminum alloy frame and a sleek black coated body, presenting a beautiful and robust appearance. Furthermore, its stability and durability are achieved through a harmonious blend of design aesthetics and power.

NFC Connection Provides An Excellent Experience
NFC-enabled smart sensors simplify network distribution, offering direct interface access. Additionally, real-time data updates and display on both your mobile phone and the WalkingPad are effortlessly achieved.
