Product information

The King Smith WalkingPad X21 Under Desk Treadmill is a revolutionary advancement towards a smarter and healthier lifestyle.

With the X21 Under Desk Treadmill, each step brings closer to a healthy lifestyle.


  • Space-saving design: The X21's double-fold design occupies less than 0.16m2 of space, making it ideal for compact living spaces. Its innovative folding technique allows for easy storage in just two simple steps, achieving both 90° and 180° folding.
  • NFC connectivity: Enjoy seamless connectivity with NFC-enabled smart sensors, providing real-time data updates and direct access to the interface via your mobile phone and WalkingPad.
  • Integrated LED digital display: The X21 features an industrial aesthetic design with a hidden LED digital display, offering a sleek surface at rest and vital workout data when in use.
  • KS Fit App compatibility: Track and manage your fitness statistics effortlessly with the exclusive KS Fit App, which also controls various functions of the X21 such as modes, start, stop, acceleration, and deceleration.
  • Durable construction: The X21 boasts an all-aluminum alloy frame and black coated body, combining aesthetics with durability for long-lasting performance. It supports up to 110kg loading capacity while weighing just 38kg.
  • Professional running track: Experience comfort and safety with the X21's four-layer professional track, simulating real running conditions and providing a generous running surface of 46 x121 cm.
  • Quiet operation: Equipped with an efficient brushless motor, the X21 maintains a constant power output while generating minimal noise (75dB) even at maximum speed under no-load conditions. For comparison, 60 dB is equivalent to "conversation in restaurant, office, background music or air conditioning unit at 100 feet".
  • Ready-to-use design: With no installation required, the X21 can be used immediately upon unpacking. Its all-in-one design simplifies the setup process, allowing you to kickstart your running routine without delay.
  • Additional features: High-strength wear-resistant rollers, detachable phone holder for added convenience, and one-key switch operation with a bold red design for a modern aesthetic.
