Are BMX bikes good for adults?

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. 

Sizing

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

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.
