Its compact and innovative features make it a popular choice among fitness enthusiasts seeking a convenient way to stay active within the confines of their homes.


Users particularly praise the X21’s double-folding mechanism, which sets it apart from traditional treadmills. This unique technology allows the deck to fold in half and then again at the top, reducing its length significantly from a standard treadmill’s size. As a result, the X21 can be effortlessly stored in a closet or pushed against a wall when not in use, making it an ideal space-saving solution.

Apart from its compact design, the X21 is highly regarded for its performance during walking and light jogging sessions. The 1.0 HP brushless motor ensures quiet operation while delivering a smooth and consistent workout experience. Users can adjust the speed from a gentle 1 mph up to a brisk 7.5 mph, catering to various fitness levels.

However, some users have noted that the folded area of the deck can be felt underfoot while using the treadmill. Although it might take some time to get accustomed to, most reviewers mentioned that this minor inconvenience doesn’t hinder their overall workout experience.

Another aspect that users appreciate is the integrated console, which is built into the handle. This console displays essential metrics like time, distance, and speed, providing users with real-time feedback during their workouts. The treadmill’s intuitive center adjustment dial makes it simple to modify settings, ensuring a seamless user experience.

Additionally, the X21 WalkingPad offers the convenience of tracking workouts and adjusting the treadmill using a smartphone. By downloading the free KS Fit App, users can easily monitor their progress, set fitness goals, and enjoy the flexibility of controlling the treadmill through their mobile devices.

Overall, the KingSmith X21 WalkingPad has received positive feedback from users who emphasize its space-saving design, quiet operation, and user-friendly features. If you’re searching for a small, efficient treadmill that can be neatly stored out of sight, the X21 is undoubtedly worth considering.
