Recommended Height:
We recommend that the total height of the scooter (from the ground to the top of the handlebar) be between the
user's hip and the bottom of their chest.
Please see our illustration for a visual example:
Adjustable Scooters:
Most commuter scooters and kids' scooters have adjustable handlebar height.
Under the specifications of each product, you can see both the minimum and maximum height settings, allowing you to
easily determine whether the scooter fits your child - or multiple users in the family.
This allows the scooter to grow with the rider and ensures optimal use over time.
Especially for Younger Children (2 - 6 years):
Younger children often prefer lighter scooters - e.g., made from aluminum or plastic.
This information is also available under the product's specifications.
“Broomstick Method” - Find the Right Height:
A simple and effective method to find the perfect height is the “broomstick method”:
Hold a broomstick horizontally in the air in front of you.
Place it at the height where you'd like the handlebar (typically around hip height - but it depends on personal
preference).
Measure the distance from the broomstick to the floor.
Add approx. 5 cm - as you are raised off the ground when standing on the scooter itself.
Example:
If you measure 70 cm from the broomstick to the floor, add 5 cm - 75 cm is the optimal total height
of the scooter.
Important to Know:
Commuter and kids' scooters are designed with adjustable height because they are not subjected to the
same stress as stunt scooters.
Stunt scooters, on the other hand, must be 100% fixed and therefore cannot be adjusted in height.
Street riding with a pro scooter is all about creativity and technical skill in raw, unpredictable city environments. It mainly takes place on streets, stairs, rails, curbs, and urban skateparks—basically, anything public space has to offer.
This style demands a lot from both the rider and the scooter. Street scooters are usually built with stronger, more durable construction, often featuring wider decks and solid components that can handle repeated hard impacts and wear from concrete and metal. That durability gives you the confidence and freedom to push yourself—whether you're just starting out or you're a seasoned street rider.
Street riding isn’t just about tricks—it’s a lifestyle and a way to express yourself. You pick your lines and obstacles, and your imagination is the only limit when it comes to what you can do in the urban landscape.
Park Machine
Park riding with a pro scooter usually takes place in skateparks full of ramps, boxes, rails, and bowls. These environments are controlled and versatile—perfect for learning new tricks, building confidence, and refining your technical skills.
At the skatepark, it's all about smooth lines, big airs, and precise landings. Park scooters are typically lighter and more agile, helping you pull off spins, flips, and aerial combos more easily. The ramps let you progress faster and keep pushing your limits as your skills improve.
Don’t have a skatepark nearby? Bring your training home! With an NKD ramp, you can practice indoors or outdoors—whether you’re just starting out or already building a solid trick repertoire. There’s a wide range of ramp models available, so you can train wherever you are, with focus and fun.
Park riding is fun, athletic, and creative—and there’s always a new trick waiting to be landed.
Level
Pick the Right Scooter for Your Level
When choosing a pro scooter, it’s important to match it with your skill level. To make things easy, we’ve divided our scooters into three categories:
Beginner to Pro
Perfect if you're starting from scratch but aiming high. These scooters are built for progression, durability, and top-level performance, so they grow with you as you level up.
Beginner to Intermediate
Great for beginners who want to learn fast and keep moving forward. These scooters are easy to handle, stable, and designed to help you develop your skills safely—from your first jumps to more advanced moves.
Beginner to Advanced
A solid choice whether you're brand new or already have some experience. These scooters can handle tougher tricks, bigger jumps, and more intense use—without sacrificing quality.
Whatever your level, you can be sure your scooter has been handpicked to give you the best start—and support your progression every step of the way.
Strength
The Strength of a Pro Scooter
The strength of a pro scooter tells you how much wear and stress it can take—helping you figure out which scooter fits your riding style and skill level. We rate all our scooters on a scale from 0 to 5 stars:
★ 0–1 stars: Light use / Beginner
Great for kids and beginners who mostly cruise or try out simple tricks. These scooters are lightweight and easy to control but aren’t built for hard landings or heavy riding.
★★★ 2–3 stars: Good strength / Intermediate riders
These scooters come with reinforced parts and added durability. They’re perfect for more advanced tricks, daily skatepark sessions, and riders looking to step up their game.
★★★★★ 4–5 stars: Maximum strength / Intense street riding
Our toughest scooters—made for serious riders. Built to handle big drops, intense trick training, and heavy use. Every component is designed with strength and performance in mind, so you can rely on your setup fully.
The higher the star rating, the more rugged and capable the scooter—so you can pick the one that best fits your style and skill level.
Lightweight
Our Take on Lightweight
Lightweight isn’t just about how much a scooter weighs—it’s about how light it is for its category. A solid street scooter can still be considered lightweight if it's built with high-quality materials, smart design, and strong but light welds.
That’s why we rate all our scooters on a scale from 0 to 5 stars:
★ 0–1 stars: Heavier build in its category
Focused on max durability and strength—so it’s heavier than others in its class. Best for intense use where strength matters most.
★★★ 2–3 stars: Medium weight
Balanced strength and weight. Built with standard materials and solid construction—typical weight for its level and style.
★★★★★ 4–5 stars: Ultra-lightweight for its class
Built with high-strength aluminum, heat-treated alloys, and design optimized for minimal weight. Feels significantly lighter than other scooters in the same category—without losing durability.
A higher lightweight rating means better control and responsiveness—especially useful for technical tricks and fast moves.
Grinds / Slides – Rated from 0 to 5 Stars
A scooter’s grind/slide performance depends on factors like deck width and shape, grind rails, surface smoothness, and material durability. Our 0 to 5-star rating helps you easily find scooters built for this kind of riding.
★ 0–1 stars: Not built for grinds
These scooters have narrow decks and lack grind-friendly features. Not recommended for ledges, rails, or curb tricks.
★★★ 2–3 stars: Light grind use possible
You can try some grinds, but these scooters aren’t optimized for it. Great for beginners experimenting with basic slides.
★★★★★ 4–5 stars: Built for grinds and slides
Designed with flat-bottom decks, box ends, and reinforced wear zones. Made from low-friction, durable materials—ideal for street riders and technical tricks on rails and edges.
Higher grind ratings mean the scooter is built to handle repeated slides—helping you grow your skills with confidence and control.
Handling / Responsiveness – Rated from 0 to 5 Stars
Handling and responsiveness show how precisely your scooter reacts to your movements—especially during tricks like spins, manuals, and jumps. High responsiveness gives you tight control and a strong connection between the deck and the handlebars, which is key for technical tricks and clean landings.
★ 0–1 stars: Loose and imprecise
There may be some play in the bar or compression system, leading to a loose and unstable feel—not recommended for advanced riding.
★★★ 2–3 stars: Standard handling
Decent control for everyday use and basic tricks. Good for beginners, but with limited precision during fast or technical riding.
★★★★★ 4–5 stars: Direct and accurate response
High build quality, tight compression, and strong bar-to-deck connection. Reacts instantly to your input. Soft wheels and solid construction give smooth, controlled landings—great for combos, spins, and serious park sessions.
The better the responsiveness rating, the more dialed your ride feels—helping you level up with confidence.
Bouncy Foam Deck – Rated from 0 to 5 Stars
The Bouncy Foam Deck rating shows how soft, cushioned, and trampoline-friendly the deck is. This foam padding is a key feature for trampoline scooters—protecting your feet during repeated tricks and making your sessions longer and safer.
★ 0–1 stars: Minimal padding
Feels more like a hard, traditional deck. Less shock absorption and not ideal for frequent trampoline training.
★★★ 2–3 stars: Moderate padding
Some foam for added comfort. Good for occasional trampoline use and beginner riders looking for a safer ride.
★★★★★ 4–5 stars: Maximum bounce and comfort
Thick, soft foam for excellent impact protection and grip—great for intense training and reducing foot fatigue during long sessions.
A higher rating means a softer, safer deck—so you can focus on landing new tricks with less strain on your feet.
Street
Street is the term for street riding with your scooter. Street is a concept of street driving with your scooter. It means cruising in the street or in the skatepark, performing stunts of all kinds - only your imagination stops you here. Street is the most used form of driving within stunt scooters and often places great demands on the design and quality of the scooter. A robust construction allows you to withstand any challenge the street may throw at you, as well as feeling more confident about yourself when you are on an adventure, whether it's the first time you're out or you've done it 100 times before.
Ramps
Ramps = riding on ramps. You often ride ramps to learn how to perform new tricks with your stunt scooter. This gives you faster self-confidence on the scooter and in general! You often find ramps on skater rinks. However, should you not be so lucky to have such nearby, we recommend that you acquire one of our NKD ramps, which allows you to practice anywhere inside and outside. There are endless models within ramps that you can ride your stunt scooter on and it's a great way to unfold and become really talented.
Slide
Slide, also known as Grind is the term for tricks that are performed by sliding on something. For example, it could be a tube, a handrail, a staircase, yes, basically anything you can think of. With the right scooter everyone can learn how to slide. It just requires you to be aware that the deck of your stunt scooter has a grind base ie. cuts that allow you to slide on things. This driving form is very popular and you can do it with your friends anywhere.
Transport
Transport refers to the scooter's ability as a means of transport. How well did it get you from A to B and how easy is it to bring along with you? Transportation via scooters has become popular in many European cities in recent years, whether it's for school or work. It is also super smart on holidays where the bicycle is too big and inconvenient, as good transport scooters often can be folded and carried over the shoulder.
Quality
Quality. This is an expression of our professional assessment of the scooter as a whole. This is based on the materials, construction, performance and estimated life of the scooter. With a high rating here, you have acquired a super good scooter that is worth showing off.

This ID number can be used by you as a consumer to legitimize the certification and find further information about what the product you are buying is approved for.
Total height:
The total height of the entire scooter. There is no right or wrong in relation to height of a scooter. Generally one can say that low scooters are oriented to technical tricks, whereas high scooters are for transport and comfort. Some scooters can be adjusted to suit you and your needs.
Weight:
The total weight of the scooter when it is complete. Heavier scooters are often made of a material, such as steel, which increases the durability and longevity. Where scooters made of lighter materials, such as aluminum, is lighter as well as easier to transport along with you. Whether you should choose one or the other depends on how much you are willing to spend and what you will be using the scooter for. A scooter does for example need to be able to stand through most and it would therefor be clever to buy it in a durable material.
Max Load:
Max load is the manufacturer's recommended load of weight on product. This set out for their knowledge and assessment of the product so that the service life is not reduced.
Deck design:
There are three types of deck design: one-piece, two-piece and foldable. One-piece decks are very durable since they are made of welded parts, whereas two-piece decks are put together with bolts. The advantage of two-piece decks is that they are often able to fold, and some models have headtubes which gives the possibility for different angles. A foldable design makes it possible to fold the scooter together so that it can be quickly taken under the arm or on the shoulder.
There are many different functions and systems for foldable scooters. If you need your scooter for commuting between the bus, train, car or just for getting around, a fast and easily foldable system is an advantage. You will quickly experience that this feature makes a difference whether you use your scooter to take with you on the trains, buses, etc.
Deck material:
The deck of the scooter is usually made of aluminum, as it is a very lightweight and durable material. The aluminum is relatively soft, therefore, it will be mixed with other metals. Aluminum is divided into alloys in which the value is determined by the mixture of metal. Higher alloy provides more durable product material.
Material strength grade:
The strength of aluminum is measured in tons, how many tons the aluminum is pressed under. A scooter deck of T4 aluminum is produced under 4 tons of pressure, where T6 means that it has been pressed under 6 tons. The more tons the metal has been pressed under, the stronger the scooter.
Deck length:
The total length of the deck's surface. The length of the deck decides how much space you have for your feet on the scooter. The longer a deck, the more space you have to stand on, where the shorter a deck, the less space you got to stand on.
Deck width:
The total width of the deck's surface. The width decides like the length of the scooter's deck, how much space you have to stand on for your feet. An example of width would be if you could have both feet next to each other on the scooter's deck surface or not. Besides that you need to have enough space to accelerate without losing your balance.
Concave:
Concave is the inward curvature of deck's surface. It helps to lock your feet firmly to the deck and thus providing a better grip, so you avoid losing balance and falling off as easy. The concave curvature is measured on the scooters deck and is measured in degrees.
Suspension:
A scooter suspension works in the same way as with cars. Movement between the scooter and its wheels is allowed. This contributes to a much higher quality scooter than one without any suspension, and gives you a significantly better riding experience on all your trips. For scooters suspension can be built by the front wheel and the rear wheel. Most often, the most expensive quality scooters have suspension on the front wheel, while the even more expensive ones have on both wheels.
Compression:
The compression system is the system that keeps your fork tightly to the headtube of the deck and reduces the slack that all scooters will suffer from the time they are being used. Thus is it with scooters and thus is it with everything actively used outside.
Fork:
Forks can be divided into two main groups: one-piece of two pieces. One-piece forks is molded or cut from one piece of metal, it gives the fork fewer weak points compared to two-pieces forks which is composed of several parts. Furthermore, the forks can be divided into forks with or without thread. Threadless forks requires a compression kit.
Headset type:
The headtube of the deck determines which headset-type the scooter is using. An integrated headset is more protected and durable than a non-integrated headset. A non integrated headset sits inside the headtube, therefore it is more fragile than the integrated headset.
Bar material:
Steel is a very strong and a durable material. Bars made of steel is very strong, but also much heavier than bars of aluminum. Steel bars caters more for scooters driven hard. Such scooters would be stunt scooters, which have to take a lot of hard impact when performing tricks. It is therefor a clear advantage if you buy your stunt scooter in a durable material.
Bar height:
The total height from the bottomof the bar to the middle of the handlebar. it is recommended that the height of the bar fits the rider. Some scooters can be adjusted by you to fit your height, while other scooters comes in fixed heights, where you then will have to pick the one most suitable for your height. The reason for this is that a stunt scooter needs to be able to take punches during tricks, so if the bar is adjustable on your tricks scooter, it will become weaker and possibly give you trouble, when performing tricks.
Bar width:
Different widths of bars suits different riding styles. With air tricks you have far more control of the trick with a wide bar, a narrow bar is better suited for technical tricks. Thus, the bar's width have to suit your skills, and it may therefore be worth considering what the scooter primarily will be used for.
Clamp size:
The clamp size of the clamp depends on the number of bolts the clamp is tightened with. Therefore what goes is that the more bolts the larger the size of the clamp, and so too it goes that the fewer bolts used on the scooter, the smaller the size of the clamp.
Outer diameter:
The bar's outer diameter is what determines the type of clamp which will fit. Thus it is recommended that the bar's outer diameter fits the clamps inner diameter. Note however that some clamps can be used in both standard bars and over sized bars.
Inner diameter:
The bars inner diameter determines the fork that fits. Whether it is a one-piece fork or a two-piece fork depends on what you imagine yourself using the scooter to. The smart thing about a two-piece fork is that it often can be folded together, which can be practical for carrying with you on the bus or the train, where with a one-piece fork the great thing is the durability, which makes it perfect for stunt scooters.
Wheeldiameter:
The size of the wheels should depend on your riding style. If you have a lot of focus on the driving experience with good flow and speed, go for bigger wheels, whereas choosing smaller wheels if you go for quick response and better control. However, it is important that the diameter of the wheel fits with both the front fork, deck and brakes.
Wheel Hub width:
The most common wheel hub width for pro scooters is 24 mm. The hub width of the scooter determines what size wheels can be mounted on the scooter.
Wheel hardness:
The hardness of a wheel is measured on the durometer scale that goes from 0 to 100 A, where 0 is the softest and 100A is the hardest. Harder wheels last longer and run faster, but are less comfortable on uneven grounds than soft wheels. Softer wheels do however wear away faster, but have a good grip and are perfect for parks and indoor use.
Core material:
Aluminum and nylon wheels each have their qualities. Aluminum wheels are the strongest but nylon wheels are the lightest. Whether it should be the one or the other depends mostly on your choice for what you will use the scooter for. It is smart to have stronger wheels for outdoors tranportation and if you want to do tricks.
Wheel design:
There are different core designs: solid and spoked. Solid core wheel is relatively heavy wheels for scooters, but their weight also provides a lot more durability and strengthens the wheels. Spoked wheels are lighter wheels for scooters, which therefore leads to a less durable and strong wheel.
Wheel profile:
What a flat profile does is it provide the absolute best and highest possible grip for scooters to achieve, where as what the narrower profile does is that it allows a lot more speed. The fork shape must match properly with the scooter wheel's profile.
Bearings:
Bearings are divided into ABEC. High ABEC values mean that the bearing is made with more precision and therefore better quality. It is recommended that your ABEC-value is high for higher speeds and lower if your wheel have to take a lot of impact, like the impact you would expect if you decide to use it for tricks.
Brake type:
There are different brake types – bolt, spring, flex fender, and brakeless fender. Bolt and spring brakes make more noise, so if you want more silent brakes you should go for a flex fender brake, however this will cause the wheels to have a slightly and overall lessened longevity. Brakeless fender doesn’t function as a brake but simply covers the wheel, typically found on Pro Scooters for serious tricks, so if you land partly on the wheel it doesn’t stop your ride.
Material strength grade:
The strength of aluminum is measured in tons, how many tons the aluminum is pressed under. A scooter deck of T4 aluminum is produced under 4 tons of pressure, where T6 means that it has been pressed under 6 tons. The more tons the metal has been pressed under, the stronger the scooter.
Axle length - Front:
The length of your scooter wheel shaft is good to have if you need to order pegs or spare parts. The front wheel axle is typically slightly shorter than the back.
Axle length - Back
The length of your scooter wheel shaft is good to have if you need to order pegs or spare parts. The back wheel axle is typically slightly longer than the front.
Core Design:
There are different core designs. The two main groups are called solid and spoked. Solid core wheels are relatively heavy wheels for a Pro Scooter but offer improved durability. Spoked wheels are lighter Pro Scooter wheels but have reduced durability.
Wheel Profile:
A flat profile provides the best and maximum grip possible for a Pro Scooter, while a narrower profile gives more speed to the wheels. The shape of the Pro Scooter’s fork should match the wheel profile.
Features:
Features are some special or additional features and elements a product may contain. This may, for example, be that a scooter is equipped with several systems for braking, an adjustable bar, side stands and a carrying strap to make it easier to carry your scooter. In addition, features can also be smart design choices that your scooter got - for example, whether it is CNC-cut or whether it might be electrically driven.
Assembly:
Almost ready to run or ready to run. Always check the scooter before use, and be aware that it is different, how you receive your scooter. if your scooter is coming complete, it is completely ready for use, whereas if it is only partially complete, then there will be few parts that need to be tightened and assembled, which must be done with standard tools.
