Changing weather and busy schedules can make indoor walking and running a practical part of a consistent fitness routine. Yet many home treadmills require a permanent footprint that can be difficult to accommodate in apartments and other compact living spaces.
The KingSmith WalkingPad X25 Series addresses this challenge with two models—the X25 Double-Fold Running Treadmill and the X25+ Folding Treadmill—both featuring running decks that fold in half for compact upright storage. Both combine speeds of up to 10 mph (16 km/h), a spacious running area and a modern design suited to home fitness. This article explores what the X25 and X25+ have in common, how the two models differ, and which home workout needs each one is best suited to.

What Do the X25 and X25+ Have in Common?
Although the X25+ includes several additional training and convenience features, both models share the same folding design, running capacity and core performance. Here is what both models have in common.
Foldable Running Deck with Vertical Storage
The X25 and X25+ use a running deck that folds in half, significantly reducing the amount of floor space required when the treadmill is not in use. Once folded, either model can be stored upright instead of remaining fully extended across the room. Integrated transport wheels also make it easier to move the treadmill between the workout and storage areas. Their streamlined appearance also allows them to fit naturally into apartments and other modern living spaces.
Walk, Jog or Run at Up to 10 MPH (16 KM/H)
Both the X25 and X25+ reach speeds of up to 10 mph (16 km/h), giving you the flexibility to move from everyday walking to jogging and faster-paced running on the same machine. A 4.5 HP brushless motor powers both models, delivering smooth and consistent performance across different workout speeds while remaining suitable for a home exercise environment.
A Spacious Running Area for a Natural Stride
Both the X25 and X25+ provide a 51.9″ × 19.6″ (1320 × 500 mm) running area, giving you enough room to maintain a natural stride while walking, jogging or running. The 19.6-inch width provides more lateral space as your pace increases, while the reinforced frame supports a maximum user weight of 300 lb (136 kg).
SoftStep™ Cushioning for a More Comfortable Feel
Both models feature the SoftStep™ cushioning system, with EVA and PET materials used to absorb impact beneath the running surface. The cushioning creates a softer feel underfoot while maintaining the support needed for a steady stride across different workout speeds.
Ready to Use Right Out of the Box
Both the X25 and X25+ arrive fully assembled, so you do not need to attach the frame or complete a complicated installation process. Simply unfold the treadmill, connect it to power, attach the safety key and begin your workout. This straightforward setup makes it easier to start using either model soon after delivery.
Other Features Shared by Both Models
- SpeedDial™ control: Adjust the speed directly from the control knob without using a separate remote.
- Device holder: Holds a phone or tablet for entertainment or app-based workouts.
- KS Fit and Bluetooth connectivity: Connect your phone or tablet to access workouts, record exercise data and monitor your progress.
- Apple Watch compatibility: Connect KS Fit with an Apple Watch to view heart-rate data during your workout.
- Safety Key: Stops the treadmill if the key becomes disconnected during exercise.
Which Model Fits Your Home Workout Routine?
Your choice mainly depends on whether you prefer a lighter, more streamlined treadmill or additional support and built-in training features.
Choose the X25 if you:
- Want the same core running performance in a lighter 104 lb (47 kg) machine
• Prefer a simpler control setup centred on SpeedDial™ and the KS Fit app
• Do not need foldable side handrails
• Want to walk, jog and run without additional built-in programs or display features
Choose the X25+ if you:

Conclusion
The KingSmith WalkingPad X25 Series brings running capability to a space-saving format that fits more easily into modern homes. The X25 is the more streamlined choice if you want a lighter machine with the essential features for walking, jogging and running. The X25+ is better suited to you if foldable side handrails, speed shortcuts, built-in workout programs and enhanced connectivity are priorities. Whichever model you choose, the foldable running deck, upright storage and ready-to-use setup make it easier to maintain a home workout routine without permanently giving up floor space.
