Introduction
If you’re looking to walk or run but don’t have enough space for a large running track, then this Walking Pad X21 has your back. It’s a compact and discrete design, which means it won’t take up much space.
In this review of walking treadmill reviews, we’ll discuss all aspects of the WalkingPad X21.
This X21 Walking Pad can be placed into a closet or behind the couch. Its minimalist design is attractive enough to fit into the modern interior of a home. In this X21 WalkingPad test, we’ll look at an in-depth review of its unique folding design as well as its performance.
The WalkingPad X21 Treadmill, however, is ideal for those who are confined in space or those who live in an upstairs apartment. If this is the case for you, read this review of the Walking Pad X21 to find out more about this compact treadmill that folds into a double.

Walking Pad X21 Review: Bottom Line
WalkingPad treadmills are the trend. For instance, the Walking Pad X21 is a WalkingPad you can actually run on, but more of a slow run. This small treadmill can be tucked away in almost any space it goes, and once you’re finished, you can fold it in two and then roll it into the closet, totally hidden from view.
The X21 Walking Pad can reach speeds of 7.5 meters per minute, which means that if you’re like me (I’m just 5’1″) and have a shorter stride (hi, I’m back!) and you’re short in your stride, you’ll be able to accelerate to a decent speed.
This isn’t a treadmill that will power you through marathon training or running for recovery. However, if you’re trying to get more active and reach the 10k step goal, the Walking Pad X21 can be a good treadmill that can help you get there.
WalkingPad is a brand with an effort to make fitness accessible. And I must say that they’ve done it by introducing the WalkingPad X21 double fold treadmill.

Dimensions/Storability/Walking Pad X21
The Walking Pad X21 is impressively small. The dimensions of the treadmill include 39.6″ L x 27.99″ W and 55.9″ in height. It can be used on floors with higher levels and in small, shared spaces. It’s only weighing around 82.5 pounds, which means that it’s among the lightest treadmills that we’ve tested, which you can still run on.
The double folding feature is useful. The deck folds in half and is then folded against the front of the deck. It is roughly the dimensions of a briefcase.
If the WalkingPad X21 is folded completely, it is possible to move it around using wheels for transportation. Two wheels are extremely small, but. We discovered that they’re too small for treadmills to spin.
Console/Walking Pad X21
The console is housed in the handle, which is connected to the uprights. When the treadmill is folded, the console and uprights remain in their place and won’t change or fold flat. The storage feature of the X21 differs from that of the Echelon Stride-6, which folds flat.
The console of the Walking Pad X21 is an LED screen that is housed in the handle’s horizontal position. The LED display allows you to view your workout performance metrics such as time and distance, speed, and calories. There’s a central dial to adjust the treadmill.
It can be pulled down and rotated clockwise or counterclockwise to alter the speed of the belt. While I’d like more adjustment buttons, the dial is easy to operate. The dial is where you will find all the treadmill’s functions.
Given the WalkingPad X21 Treadmill being as tiny as it is, I’d rather just place it right near my TV for use by me personally. It’s good to have alternatives, however.
KS Fit App
Another method to modify and monitor your performance is to install your KS Fit application. The treadmill’s manual contains a QR code for it, which you will need to scan and download. The X21 Walking Pad can be connected to the app via Bluetooth, which means you can begin/stop the treadmill and adjust it using your smartphone.
It also shows your current speed, average speed, and the KS Fit app also shows your steps, average speed, and the current pace. You can alter the speed of maximum and minimum.
Frame/Walking Pad X21
The Walking Pad X21 has an all-aluminum frame made of alloy. It’s powder-coated black to shield the treadmill from scratches and bumps and also enhances its appearance. The X21 comes with multiple stabilizing feet to prevent the treadmill from tilting or shifting during use.
The footrails are small, but I like them better than the footrails on the Walking Pad R2. People with a larger size shoe should be wary of walking on the footrails because there isn’t much room for error.
The treadmill is quite close to the ground, which means you shouldn’t be concerned excessively. If you do fall off your balance, don’t be putting my trust in the handrail. It’s not strong enough to withstand a person’s entire weight.
I love the fact that WalkingPad includes a handrail, but it’s more of a console and also an indicator of your position rather than a security feature.
Motor/Walking Pad X21
The Walking Pad X21 isn’t just a small treadmill. It is also a quiet treadmill. The quietness can be attributed in part to the motor that is brushless. It’s not the strongest motor, but it does make sense given the kind of treadmill that the X21 WalkingPad is.
Deck
This 18″ x 48″ belt is a little smaller than what you would normally see on a treadmill that runs. It is feasible for you to use the WalkingPad X21. It’s not as tense as you’d think; however, I would recommend running at a higher rate (more minutes of walking) to make your stride shorter. If you’re a long-legged runner, the X21 may not be a good fit for you, particularly near its 7.45 speed limit of 7.45 mph.
There isn’t much cushioning on the Walking Pad X21. This deck sits on the more firm side of the treadmill’s running spectrum. The width of the treadmill does not allow for many shocks. I was impressed by the underfoot sensation. If there’s one thing I’d alter, it would be the way in which it folds. Based on how cushioned your shoes are, you might see this more.
Features & Accessories/Walking Pad X21 Review
It’s no surprise that this tiny treadmill has very few features. This WalkingPad Treadmill is a compact console with only a tiny amount of space aside from the essentials. For the X21 Walkingpad Treadmill, this is a benefit, as it makes the treadmill as compact and compact as it can be.
I never felt as if I was missing anything with the X21, as it’s easily transportable where you’re required, but it’s not intended for prolonged, running exercises that require lots of hydration and nutrition.

Performance
The Walking Pad X21 is winning me over. I was skeptical that such a large treadmill could be suitable for running. However, WalkingPad has proven me to be wrong. Again. As with its predecessor, the WalkingPad R2, the WalkingPad X21 is able to function as an exercise treadmill.
Its sleek and compact design will not hinder you from running miles after miles. Of course, it’s not a treadmill for training for marathons. However, it’s great for runners who are new or who need an indoor option. When I’m not testing treadmills, I exercise outdoors whenever I can.
However, there are a variety of situations that make running outdoors difficult or unsuitable. There are environmental and weather issues. I’ve also had the desire to run in the evening, when it could not be safe because of crime or coming across wild animals. This Walking Pad X21 is a great option for a seasoned athlete like me or for a novice to the sport.
It is important to talk about the limitations. If the X21 was the ideal running treadmill, nobody could see a reason to purchase a bigger space-hogging machine. However, the X21 isn’t able to incline or decrease. It’s not cushioned as most runners would prefer.
It’s a speed limit of 7.45 miles per hour, and could not be enough for everyone, even on easy days. It’s certainly not fast enough or large enough to allow you to stretch your stride and do certain speed intervals.
Should You Buy The Walking Pad X21
If you’re like me, you’re not able to find enough space for a treadmill within your home. Maybe you’re just like me and reside on the upper floors. This WalkingPad X21 Treadmill is the perfect treadmill for us.
It’s very compact and can fold up to only 8.9 inches wide. After you’ve finished walking on the deck, it is possible to fold it in two and place it against a wall or in the closet.
Other attractive features include the small size and quiet motor. Although this isn’t one that you can use for long distances, for a few steps, it will do well. The hinge folds down on the deck may require some time to adjust to, but it’s not a huge cost to pay for the treadmill that occupies just a tiny space, as it does with the Walking Pad X21 does.

0.5 to 12 km/h
A few people are able to use this WalkingPad X21. Because it's a smaller 47.6" lengthy deck, those with longer stride lengths aren't in a position to run completely on it. Its 60" lengthy decks will be the best for all strides. If you're running with a shorter stride, you'll be able to jog the X21. It can only go up to 7.5 speed, which is a jogging pace for some, but an incline for other people.
The WalkingPad treadmills don't come with incline features. Because of their small size and low-profile design, these treadmills aren't designed for walking at an incline.
Natural Running Feel - Running belts of WalkingPad X21 are 121 cm long and 46cm wide, which makes it spacious and comfortable for running and walking. We employ durable PET and a shock-absorbing EVA for the running board to guard joints. It has a maximum load capacity of 110kg.
