KingSmith WalkingPad X21 foldable treadmill
Luxury design and smart functionality
The X21 goes from 0.5 to 12 km/h and is suitable for both slow walking and vigorous jogging. This WalkingPad combines a modern design with advanced technology for a stylish and efficient workout from home or the office. This premium WalkingPad is designed for people who want to stay active without compromising on living space or interior design. With its ultra-thin design, high-quality finish, and innovative double-fold technique, the X21 is one of the most stylish and practical WalkingPads on the market.
Innovative double-fold system
The X21 distinguishes itself with its smart double-fold mechanism. This allows you to fold the treadmill into a compact size that can be easily stored upright against a wall or in a cupboard.
Ideal for apartments, modern homes, offices, and other spaces where efficient use of space is important. After your workout, you can easily move the treadmill thanks to the integrated transport wheels.
4-layer cushioning: comfortable walking and running
The X21 offers a comfortable and stable training experience. Thanks to the spacious running surface and high-quality construction, you can train safely and smoothly from home. The advanced 4-layer cushioning helps absorb impact and reduces stress on knees, ankles, and joints. This makes every step feel more comfortable than walking on hard outdoor surfaces.
Whisper-quiet performance
With the X21's quiet motor, you can train almost silently. This makes the treadmill perfect for use in offices, apartments, or homes where you do not want to disturb others. Walk or run at any time of the day, even when others are sleeping or working.
Simple control with Speed Dial
The operation of the X21 has been kept deliberately simple for maximum user-friendliness. You can effortlessly adjust the speed while walking or running via the smart Speed Dial knob.
- Press to start
- Turn right to increase speed
- Turn left to decrease speed
- Press lightly to stop gradually
This means you don't have to fiddle around looking for buttons while training.
Premium finish and modern appearance
The X21 features a strong aluminum construction with a stylish black finish. The minimalist design fits perfectly with modern interiors and makes the treadmill an elegant addition to your home or office space.
This combination of design and quality earned the X21 several international design awards.
Smartly connected via the KS Fit App
You can easily track all your training data with the KS Fit App. View statistics, set goals, and monitor your progress directly via your smartphone.
In addition, the X21 supports NFC pairing for a quick connection with compatible Android devices.

What makes WalkingPad unique?
WalkingPad has made a name for itself worldwide with an innovative approach to compact treadmills. Unlike traditional models, which are often large and heavy, WalkingPad focuses entirely on smart, space-saving solutions for everyday use.
The brand is known for its minimalist designs, quiet motors, and practical folding systems. This makes WalkingPad treadmills not only functional but also perfectly suited for use in apartments, home offices, and smaller spaces.

Frequently asked questions
How does the delivery of my treadmill work?
At LoopbandSpecialist, we ensure your new treadmill is delivered safely and carefully.
Standard delivery (free):
Your treadmill will be delivered on a pallet, as close as possible to your front door (or the first accessible location for apartments or flats). The planning department or the drivers of the transport company will contact you by phone in advance, using the number you provided during your order, to schedule the delivery with you.
Delivery with installation (additional cost):
For many models, you can directly choose delivery with installation on the product page. In that case, our technicians will fully assemble the treadmill and deliver it ready for use at your desired location.
If this option is not listed with the product, please feel free to contact us. We are happy to discuss the best solution for your situation. We will then create a customized delivery plan.
Does my treadmill arrive pre-assembled?
The treadmill is delivered partially pre-assembled. This means that most of the treadmill is already assembled, and you only need to secure a few parts - usually the uprights, the console, and some screws. Thanks to the clear manual, you can do this yourself within 30 to 60 minutes, depending on the model, without needing much technical knowledge.
Would you prefer us to take care of everything for you?
Then you can opt for our full assembly service. One of our technicians will deliver the treadmill to your home, fully assemble it, test it, and set it up for use. This way, you don't have to worry about anything and can start training immediately. View more information about our installation service here.
What about the warranty?
At LoopbandSpecialist.nl you always buy with full warranty and security, because we go further than other fitness stores.
All treadmills come with a standard minimum 2-year warranty on parts - regardless of the brand. For some brands, we even offer extended warranty periods, for example a longer warranty on the motor or the frame. The exact warranty conditions may vary per brand or model.
Tip: Always check the product page of your treadmill for specific warranty information.
Do you have a problem or malfunction outside the warranty period?
Even then you can still contact us. Our own service department can quickly help you with repair, maintenance or replacement parts, so your treadmill runs like new again.
Should I maintain my treadmill myself?
Yes, regular maintenance keeps your treadmill in top condition. This includes cleaning the running deck, lubricating the treadmill, and checking the tension. You'll find a simple maintenance schedule in your treadmill's manual, or you can opt for our maintenance service package.
Can I move or store my treadmill?
Most treadmills for home use are equipped with transport wheels and can be folded. This makes them easy to move and saves space when you are not training.
What makes our service better than the rest?
At LoopbandSpecialist.nl, we know how frustrating it is to be without your fitness equipment. That is why we handle warranty claims quickly and efficiently, something many other fitness stores simply do not do. Where others sometimes get stuck or are even unable to resolve all issues, we ensure that you are always helped.
What truly sets us apart:
-
In-house stock of spare parts - We keep commonly used parts in stock as a standard, so that in the event of a defect, we can take action immediately without being dependent on external suppliers or long delivery times.
-
In-house technical expertise - All our repairs and inspections are carried out by our own experienced technicians. This allows us not only to resolve problems faster, but also to repair them professionally and sustainably.
- Direct communication - You always have direct contact with our team. No intermediaries, no unnecessary waiting - just clear and personal service.
Thanks to this approach, we can handle warranty and service cases much better (and faster) than our competition, which is the deciding factor for many customers to choose LoopbandSpecialist.nl.
Moreover, we remain available to our customers even after the manufacturer's warranty period has expired, so you can always count on support whenever it is needed.
We guarantee quality, reliability, and direct support, so that you can continue to enjoy your product.
