About KingSmith 

KingSmith Fitness Technology Co.,Ltd is the company that introduced the world to intelligent, durable, and foldable treadmills, now known as walking pads.

The purpose of KingSmith’s innovative pads is to make it possible to walk and run in our homes or offices without the limitations of space, time, and weather.

Since the company’s birth in 2015, its popularity has spread like wildfire. Bringing more advanced, luxurious walking and running models to the fitness market, their US sales reached over $10 million in 2021. 

KingsSmith WalkingPads are available in 70+ countries and on retailer’s sites like Amazon, Walmart and Walkingpad.com, so they’re also very accessible to consumers.

The walking pads have won several design awards (Red Dot, IF, GOOD). In fact, WalkingPad X21, the model we’re discussing today, was named one of the top inventions of 2022 by TIME Magazine.

The brand is continuously improving their products through customer’s feedback, aiming for excellence at all times.

What is WalkingPad X21?

WalkingPad X21 is a type of home treadmill KingSmith released in 2022.  It has the same foldable and lightweight characteristics as the previous models. 

However, there are some appealing features. The treadmill has a modern look with an integrated luxury frame, plus a touch screen and hidden LED display. The powerful but brushless motor is a good fit in any house, without ruining your aesthetic.

Who is WalkingPad X21 for?

A member of the KingSmith founding team was advised by his doctor to exercise more. But he struggled to find time for his health, even though he knew he must give up his sedentary lifestyle. 

So, he developed a WalkingPad that can be done standing while working, absolutely any time, without restrictions. 

Today, walking pads are for a wide range of people, such as: 

People of all ages looking for a safe workout

This foldable magic can be used by people aged 14 to 60 (even beyond if you feel strong and agile).

Thanks to its user-friendly handrail control and installation-free setup, almost anyone can easily operate it without any technical background. 

Safety is also a top priority of WalkingPad, offering features like hand operation controls, beginners speed (0.3 mph start), a safety clip, and an auto-stop function. These features can ensure the well-being of recovering or senior users. 

The anti-slip surface and four-layer running belt add further security,  providing joint-friendly, stress-free running.

Home workout lovers

 X21 is a perfect choice for those who prefer to train in the comfort of their home. Whether you don’t have access to a gym or find the weather isn’t suited to your daily walk, this anytime fitness option is simply amazing.

Time-poor professionals, busy parents, night owls

Individuals with children or those with busy home-office schedules may find it challenging to leave the house to train. Childcare can also be demanding, but WalkingPad X21 has got you covered. 

It can be used in front of the TV, even while the kids are toddling around (built-in child lock). Use it with WalkingPad’s adjustable height standing desk (or your own), stay fit while working, and maintain good posture.

Can’t sleep? Its low noise operation lets you move and burn calories without waking everyone else up.

People with limited space  

If you have limited space for traditional, gym-built equipment, this foldable treadmill could be your ideal choice – even if your house is tiny.

The WalkingPad’s X21 double-fold design takes up less than 0.16m² of space and can be stored in a small, fixed upright position.

Those prefer an up-to-date equipment in a modern house

The aluminium alloy frame, black-coated body, and hidden LED display give its appearance a luxurious look, even while folded.

If you need a treadmill that fits a modern or minimalist aesthetic, X21 is a good pick.

Users who want to track their workout for motivation

Easily connect your smartphone with X21 to track and save your steps, calories, time, and distance. You can also control your speed through the app. 

The bluetooth, NFC and WiFi integration allows for easy connection!

People wanting to lose weight and burn fat

WalkingPad X21 users can enjoy walking, jogging, and running anywhere, anytime.

This will increase the heart rate and energy expenditure, resulting in energy balance, faster metabolism, and weight loss. Especially when combined with a healthy diet!

Aerobic exercise may also improve blood circulation, which can lower blood pressure and improve heart health.

Things to consider before buying WalkingPad X21 

To save you time and money, here are a few things to consider before buying the X21 WalkingPad.

Weight Capacity

You want to ensure that X21 can comfortably support your weight. Some higher-end models, like X21, support up to 240 lbs (110 kg). 

Check if this fits for you before ordering. 

Motor Power 

The performance of the WalkingPad is directly influenced by the power of its 1.25-horsepower motor.

While X21 does not suit high-intensity workouts, it has a robust motor that suits most weight loss and fat-burning purposes. 

Speed

Depending on your fitness level and workout preferences, speed might come to be important! 

Those looking for a low-impact option because of knee pain, who want to walk while working, improve posture, and support overall health will benefit from using WalkingPad X21. This model has a walking and jogging speed of 0.3-4.2 mph (0.5-8 km/h) .

Those who need higher speed to improve fitness and lose fat can go up to 7.5 mph (12 km/h). This can even be a good supplement for marathon training. 

Either way, X21’s speed is perfect for a wide range of people at different fitness levels. 

Dimensions and Portability

You want to make sure that it fits well in your house and have enough space to store it.

If you are looking for features like transport wheels, a folding design, and lightweight construction for portability and space-friendliness, X21 is perfect. This foldable model can be conveniently stored under a bed or sofa.

Control and Display

A model with an armrest control system and clear, real-life data sharing speed, calories, time, and steps can keep you motivated. It also allows you to adjust the speed and other settings effortlessly while running.  

The X21 was also designed with these details in mind, plus additional aesthetics consideration with a modern hidden LED display. 

Shock Absorption and Protection

A walking pad that offers shock absorption to protect your joints from impact can be really key. Additionally, it should operate quietly so that your exercise doesn’t disturb others who may be nearby or asleep.

Warranty

When purchasing any product, it’s always wise to check if it comes with a warranty covering the frame, motor, and parts for a specified period of time.

Most WalkingPad products, including X21, come with one-year warranty and a 30-day return window.

This will provide you with peace of mind in case there are any manufacturing defects or performance issues.

Budget 

Lastly, take into account your budget. Opting for high-end models may come at a price whereas basic ones tend to be more affordable, but with fewer features you want.

It’s important to strike a balance between your budget and KingSmith’s range of models to ensure you get the best value.

I’ll be sharing info about some alternatives later on, so if X21 isn’t your pick, stay tuned.

Here’s what real WalkingPad X21 customers say:

“Fits perfectly in our small ish apartment! Really quiet. I run/walk on it at night and my husband says he can never hear it!”

• B. N.

“Absolutely AMAZING!!!!!! I moved into a smaller house and had to get rid of my old treadmill. I can’t believe I’ve now got one that is just as good and folds away and just slips into a small space. I love everything about it. The design is sleek and ergonomic. The display is great and it’s quiet. Massive fan!”

• J.N

“Great quality, sturdy and well constructed! Seamless transaction from the order to the easy setup!”

• P.L

“Incredibly worth the money. We live in AZ and it’s too hot to walk outside for a good portion of the year. I got this for my son so he could use it for online school, sensory (walking barefoot safely) and exercise. 

The item is perfect, easy to put together and reliable. My only constructive feedback is that the app could use some work and the item is a bit hard to move around on carpet. All things I’ve learned to work around. I love that it doesn’t take up space in the house when it’s not in use.”

• Jessica

“I had a large treadmill several years ago And I couldn’t justify getting another because of the amount of space it took up… until I came across this foldable treadmill!!! It is super nice and this King version I bought allows me to run or walk, I couldn’t be happier. 

I use it and then place it out of the way in my office / workout room. The app tracks your time and effort and connects to my health app. It’s very cool and my friends were surprised how nice it was for the price, considering big treadmills that are nice are expensive. Thank you!!! Great product!!”
