Instead of wasting valuable time browsing through several online bike stores or visiting bike shops in your neighborhood, you can shop from the comfort of your own home. You may read through our instructions, make a choice, and then go out to make your purchase right away.

Here are the bells and whistles to finish it off.

What is BMX Bike?

Bicycle Moto Cross (BMX) is an acronym for this sport (X). The history of BMX racing may be traced back to the late 1970s in California. In the 1980s, the practice of riding BMX bikes became popular, and it is considered to be the forerunner of mountain biking.

Riding BMX bikes is more of a way of life and a way of life than it is a competitive activity. The sport is officially recognized as a component of the Olympic Games’ competitive games competitions.

A BMX bike is an off-road sports bicycle that is smaller in geometry and look than a regular bicycle. It is mostly used for racing and doing tricks and stunts. These bikes are a lot of fun to ride, they’re durable, and they’re practically unbreakable.

There are two types of BMX bikes:

  • Production BMX bikes
  • Custom BMX Bikes

Production vs. Custom BMX Bikes

Due to the fact that children are most likely BMX novices, it is anticipated that you would buy a BMX cycle as a secondary purchase. However, as they progress in their careers, they are likely to choose a model that has been customized for them.

BMX bikes for sale in the production market are offered as a complete package that includes the following components: chainset, wheels, saddle, seat post, handlebars, grips, chains, frame, and wheels. According to the manufacturing firm, the BMX bike is delivered in its whole.

Because they are purchased and used without intervention, the factory BMX bikes represent excellent value for money. You may, however, adjust the seat position as well as the length of the stem and cranks to suit your preferences.

Custom-built BMX bikes provide a great deal of versatility. It would be necessary to acquire separate components from either a single manufacturer or a number of different manufacturers in order to construct a bespoke BMX. You may customize your child’s bike by selecting a chainset, handlebar, and brakes that fit his or her tastes.

The prices of framesets vary based on the material used – steel frames are lightweight and thus more expensive than other materials. When purchasing a BMX frameset, you will also need to factor in the cost of a fork, since BMX framesets do not come with forks included.

As a result, if you want to create the ideal customized BMX bike for your child, you’ll need a substantial investment.

Why Size Matters

The better the fit, the greater the performance, and there is no such thing as a one-size-fits-all solution when it comes to BMX bikes.

Finding the appropriate bike size for your 7-year-old kid will not only assist him in easing into the sport, but he will also get more bang for his buck as he shreds away on the appropriate-sized bike.

It is common to feel cramped and jolted while riding a bike that is too small for the rider’s height and body type. Anyone above the age of six who has ever ridden a tricycle will understand what I’m talking about. Take note of how your elbows are stuck in the air, nearly parallel to your body’s surface.

Not only does this make it difficult to maintain control, but it is also very unpleasant. Maintain simple control of the bicycle for your 7-year-old kid.

When a bicycle is excessively large, it is common for people to remark that the bicycle is too “heavy.” The fact that a heavier bike model was used for the task of a lightweight BMX, of course, is a possibility, and we shall discuss this in more detail later.

A bike that is too large for your 7-year-old will have the same appearance as when your kid is wearing an excessively large coat.. His arms will be unable to reach and he will seem to be drowning.

BMX bikes are designed to be ridden while standing up on one’s feet. The seat is only used very seldom, and only while traveling at a very modest speed. If your kid is unable to manage the bike while standing or if, when sitting down, the bike seems to be the same size as a normal mountain bike, the BMX is too large and you should consider reducing the bike to a smaller size.

Here is a sizing chart that may be useful.

Rider Height4 ft (below)4 ft 2 in4 ft 5 in (above)
Rider Weight55-60 lbs60-80 lbs80-110 lbs
Wheel Size16x 1 in18 x 1 in20 x 1-3/8 in


On the bike, your kid should be able to stand up with relative ease. He will have a little stoop in his shoulders. Arms are relaxed, and elbows are bent at a modest angle to the body.

When it comes to your child’s BMX bike, size matters a great deal. Make sure to test ride any bike before purchasing it, and don’t be hesitant to seek an expert’s advice if you aren’t confident in your ability to determine whether or not your kid is riding the proper size..

What to Consider Before Buying

Top Tube Length

The top tube should be shorter the smaller the kid is in order to ensure that they are comfortably fitted. Additionally, the closer your kid is to the upper end of the 16′′ age range, the longer the top tube will need to be. When searching for 16 inch BMX bikes, bear in mind that there is a lot of variety in the geometry and frame size of the various models.


Additionally, your child’s weight may make a significant impact in how much fun he or she has riding a bike. A lighter bike is still essential in helping your kid succeed, even though the weight of the bike is much less important than the weight of a racing BMX bike or the weight of a pedal cycle for longer distance riding. For young children, learning to leap and do feats on a large bike may be difficult (and sometimes dangerous) due to the weight of the bike.

Frame Material

Steel is used to construct the majority of BMX bike frames. Particularly important is the use of Chromoly steel in the construction of the bicycle frame (or CroMo for short). This is a high-quality steel that will last for a very long time with little maintenance. Hi-tensile steel is still a little heavier and less durable than regular steel, and it is often seen on lower-priced bikes from large box shops.

If your kid intends to use the bike for racing as well, you should search for a BMX bike with an aluminum frame, which is more durable. Aluminum frames are much lighter than steel frames.


BMX bikes are available with one, two, or three-piece cranks. Avoid buying bicycles with one-piece cranks since they are less expensive but less durable. Cranks with two pieces are preferable, while three-piece cranks are the finest. Strength and durability are improved, as is their ability to differentiate more expensive bicycles from less durable alternatives.


The width and tread of the tires of your kid’s bike should be appropriate for the kind of riding that your child will be performing on the bike. However, you may easily change out the tires later if need be. Look for a wide tire with a slick tread while riding in the skate park or on the street. A tire with greater tread, comparable to that of a mountain bike tire, will be required for dirt jumps or the pump track.

It has already been stated that you should change out the standard tires on your kid’s bike with narrower tires that will roll quicker on the BMX track if your child plans to participate in some BMX racing as well.


U-brakes and V-brakes are two different kinds of brakes that may be found on the motorcycles on this list, as you will see.

Bike models designed specifically for freestyle riding often have U-brakes fitted. Their location within the rear triangle ensures that the rider will not be inconvenienced by their presence. V-brakes are more often seen on BMX bikes that are designed for racing rather than riding.

Top 5 BMX Bikes For 7-years old

As parents, we want our children to be safe when riding their bicycles, which includes choosing the appropriate size for them. While seated in the seat, your child should be able to reach the ground with their hands. It’s also important not to have their knees come up too high because the seat is too low or the wheels are too tiny, since this may result in injury.

So, what are the finest bikes for children aged 6 to 8 years old? When it comes to bikes for this age group, you’re normally looking at 18- to 20-inch frames, which often include big-kid components like kickstands and gears. When it comes to purchasing a new bike for a growing child, where do you even begin? When your kid grows into these sizes, durability and excellent brakes are two of the most important characteristics to look for.

We’ll help you through the process of choosing a safe and popular decision.

While the price range of under $300 may not seem to be very high, there are many BMX bikes in this price range that are more than capable of competing with competition-level models.


The Mongoose L80 is a mid-range freestyle BMX bike that “always delivers” great performance, and it is considered to be one of the finest BMX bikes of all time by many experts and riders. This bike can surpass even the most costly versions on the market thanks to its better components and outstanding workmanship.

Whether you’re riding in a skatepark, the urban jungle, or even on dirt tracks, the Mongoose L80 is up to the task, providing a comfortable ride without compromising speed or performance.

It utilizes the Mongoose 4130 BMX frame, which is constructed of Chromoly, a durable steel alloy composed of chromium and molybdenum, to provide a stable ride. This material is very durable while being exceptionally lightweight, allowing you to gain more air on jumps and control the bike with more ease.

The frame is designed with a built-in headset for a more rider-friendly shape. Its length is 20.75 inches, which makes it the perfect size for the overwhelming majority of individuals.

For example, unlike other inferior freestyle bikes, the L80 is equipped with large volume 2.4” tires, which provide lots of traction and make it simpler to perform complex feats. While you have thinner tires, you have less touch with the ground, which may make it more difficult to maintain control and comfort when falling.

The Mongoose L80 is a freestyle bike in the top mid-range, as shown by its 25x9T gearing with cassette driver and robust 2-piece 175mm cranks, which are both standard on this model. Pedaling on less expensive bikes may be a chore, but with the L80 it’s like pushing butter through butter.

This improved gearing and drive system enables you to build up speed more quickly and with less effort, allowing you to accelerate into ramps and tricks with more ease. This amount of gearing is essential for riders who want to take advantage of skateparks.

Freestyle bikes must be durable in order to withstand the stress of falling on them so often, which is why the L80 is equipped with an alloy 4-bolt treadless stem and a 2-piece bar. This configuration is much stronger and more lasting than the alternatives, which are often seen on lower-quality devices.

In the opinion of one reviewer who rode the bike at a local skate park, the bike was great and equivalent to a bike for which he would have spent 5 times as much a decade earlier.

The L80 represents excellent value for money since you are receiving high-quality components that are constructed from lightweight materials at a reasonable price. When it comes to quality, cheaper bikes can’t compete; conversely, more costly bikes do just slightly better.


  • To begin with, the bike is very light.

Additional Equipment Needed to BMX

Because BMX is a bike sport, after you have purchased a bike, you are ready to start racing! However, there are certain additional precautions you should take to ensure the safety of your kid.

The use of a helmet is essential in ensuring the safety of the little man. For some reason, helmets are associated with a negative connotation among 7-year-olds, who believe they are unnecessary or even silly.

Believe me when I say that the stigma fades among the better and more experienced motorcyclists. At the skater park, the only people who would make fun of you for wearing your helmet will be those who don’t even know how to skate themselves.

Elbow and knee pads are also a good idea while playing sports. Even though no one has ever died as a result of a scratched elbow, it still hurts like the dickens, and believe me when I say that your kid will be in tears. A great deal.

However, apart from that there isn’t much more to consider while riding a motorcycle. Find a skate park, construct a ramp, or enter some races to get your adrenaline pumping. Sporting BMX is a fun activity that your 7-year-old is sure to like!

Frequently Asked Questions

How do you pick a bike size?

There is a bike height chart that recommends the appropriate bike size based on the user’s height and weight. You may use it as a point of reference.

Take off your shoes and stand with your legs spread (at a distance of 6-8 inches), then measure the distance between your crotch and the ground. After that, use the following formula:

City bike: Leg inseam (cm) x 0,685 = Your frame size

Mountain bike: Leg inseam (cm) x 0,66 = Your frame size

Road bike: Leg inseam (cm) x 0,70 = Your frame size

What age is a 20 inch BMX bike for?

BMX bikes with 20-inch wheel size are for children from 7 years and above. However, some adults still ride BMX bikes with this size.

Why are BMX bike seats so low?

The low seat provides adequate room for the rider’s legs to be able to move freely while riding, reducing the impact on the ground. As a result, individuals may prevent damage to the genitals or the perineum by doing so. As you are probably aware, one of the most important requirements for BMX bikes is protection.

Are BMX bikes suitable for long-distance?

BMX bikes are intended for use on short tracks or in competition.

It is not recommended for long distance riding unless you are prepared to experience discomfort as a result of the single gear and the usual frame shape.

It is possible to explain that the tiny size is intended for larger leaps. The BMX bikes are often equipped with 20-inch rim rims, durable frames, and just one gear to assist the riders in jumping.

It will take time for the procedure to take effect, but once it does, they will be doing feats that even you will enjoy! The optimum age range for 16-inch BMX bikes is between 5-8 years. 20-inch BMX bikes are suitable for youngsters aged seven and above, but keep in mind that there are additional considerations. While age is a consideration, the height of the kid and the length of the top tube are also important.

Why are BMX bikes smaller?

BMX bikes are equipped with conventional 20-inch wheels, durable frames, and a non-geared crank to provide additional assistance to riders when doing acrobatics or tricks. It is intended that the design, form, and material will offer structural resistance as well as agility and the required speed.

Can kids ride BMX bikes for long distances?

According to what we said before, BMX bikes are designed especially for short-course racing or track performance. Even though they have seats, road bikes, cruiser bikes, pedal bikes, and hybrid bikes are never as comfortable for extended rides as other types of bicycles. Long-distance riding is not possible with this frame shape, unless you want to torment your child with it. BMX bikes, on the other hand, can be ridden on streets that have obstacles.

When is it not good to buy a BMX bike for my Child?

The versatility of BMX bikes allows riders to do acrobatics and tricks, have fun in skate parks and on city streets, or just cruise about the neighborhood. When planning lengthy family excursions, such as bike camping or bike touring, it is not recommended that you purchase a BMX bike for your kid to use only for this reason. Choose another pedal cycle with gears instead, and only use the BMX bike for short-distance riding when absolutely necessary.
