Are BMX Bikes Good for Adults? (Bike Sizes Explained!)

BMX bikes are one of the most popular bikes for children. They are lightweight and designed for a good time. But are you too old to ride BMX bikes?

Are BMX bikes good for adults?

Yes. There are various sizes of BMX bikes that can be bought according to the height of the adult. They are not limited to kid sizes. If it fits you and your riding style, then it is suitable for you. Top tubes equal to or larger than 20 inches are recommended for the adults to ride.

Riding bikes is open for everyone. BMX bikes have been categorized for young people and even adults over 60.  The oldest BMX racer in the United States is a woman who was 69 years old!

Whether BMX bikes are good for you or not depends on the sizing, your experience, tolerance, physical health, and balance. 

You might think that they are only for kids because of their small size. But they are built in small sizes to perform stunts. The smaller the size, the bigger the jumps. This does not mean they are limited to children. 


Without the correct bike size, riding a BMX bike will not be comfortable for you. So it’s best to figure out the proper size for you in a bike shop.

Your experience

If you don’t have experience riding a bike, it’s better not to start with a BMX one. This is because BMX bikes are a bit compared to standard bikes. Try out the standard ones and after a few months, you’re ready for a BMX bike!

Your tolerance

Your patience level definitely plays a role. You can’t be a pro right away. It can take some time to completely get used to riding BMX bikes. A proper month is required at the very least. 


Balance is required for any sort of bike riding whether it’s a BMX bike or a standard bike. You have to learn to perfectly balance a bike to properly ride it. Achieving perfect balance is required even more when it comes to BMX bikes.  

Physical Health

Your physical health is also a factor. If you run out of stamina fast or have previous health conditions which may affect your bike riding, then it’s not recommended. 

Just a reminder, you’re never too old to ride a BMX bike. Proper practice can help you achieve the level you want to for your BMX bike. You can do it to perform stunts or just as a recreational activity.

What size BMX bikes do adults ride? 

Adults usually ride BMX bikes that have a frame size of larger than 20 inches. But the top tubes can be 20.5 to 21.5 inches.

There are larger sizes such as 22, 24, and 26. If you’re less than 5 feet in height then it’s better to go for sizes lower than 20 inches such as the Junior. Standard BMX wheel sizes are typically 20 inches. 

A cruiser wheel size (24 inches) is suited for taller and older people. 

The correct size will depend on your age, height, and your comfort.

How do I choose the right size BMX bike? 


Anyone less than the age of 6 should not be riding a BMX bike. Generally, kid-size bike frames are 15 to 18 inches. They are categorized as Micro Mini, Mini, and Junior. 

Height & Weight:

The height is mainly what decides which size is correct for you. If you have a height lower than 163 cm then you should go for a bike frame that is lower than 20 inches and a wheel size of 20 inches.

If your weight is over 100 pounds then a top tube length of over 20 inches is suggested.


Where you will be riding should be considered too. If you’re purchasing a BMX bike for riding in the park, shorter top tubes will be enough.

If you’re a trail or dirt rider, longer top tubes will be needed around 20 inches. The ones for street riders are more in the middle of the scale and mostly depend on your preference. 


The experience is divided into four categories. They are Beginner, Expert, Master, and Pro. If you’re a beginner when it comes to BMX bike riding, frame sizes less than 18 inches are usually fit for beginners.

This is if your body height is between 12 to 18 inches. BMX expert is for intermediate riders who are around 130 pounds and 140cm in height. Frame size from 20 to 20.4 top tube inches is for this category.

BMX Master is for advanced riders with a frame size between 20.5 to 21. BMX pro is for professional riding and applicable for riders who weigh more than 165 pounds. The frame size for this category is over 20.5.
