Can Adults Ride Bmx Bikes

Updated on July 5, 2022

Adults can ride 20-inch BMX bikes as long as they wear the appropriate safety gear. Adults must have higher balance and coordination in order to successfully ride this type of bike, making it more difficult than other bikes.

What size BMX bikes do adults ride? 

BMX bikes with frames larger than 20 inches are quite prevalent among adults. It is possible that the diameter of the upper tubes can range from 20.5 to 21.5 inches.

In terms of sizes, there are 22-24 and 26-inch options. Shorter people should go with a Junior or a lower size. The diameter of BMX wheels is typically 20 inches.

Taller and older riders will benefit most from the 24-inch cruiser wheels.

Your height, weight, and age all play a role in determining the best shoe size for you.

How do I choose the right size BMX bike? 


Anyone under the age of six is prohibited from riding a BMX bike. The majority of children’s bikes have 15 to 18-inch frames. This group includes Micro Mini, Mini, and Junior.

Height & Weight:

Your height is the most critical consideration when deciding your shoe size. To be able to ride a bicycle, you need to be no taller than 163 cm and have wheels no larger than 20 inches in diameter.

If you weigh more than 100 pounds, a top tube length of at least 20 inches is recommended.


Think about where you’ll be riding as well. If you’re looking to buy a BMX bike to ride at the park, you can get away with shorter top tubes.

The length of a trail or dirt rider’s top tube must be at least 20 inches. When it comes to street-riding bikes, it’s all about personal preference.


The experience is divided into four parts. There are four levels: Beginning, Intermediate, and Advanced. For beginners, the smaller the BMX bike frame, the more accessible it is.

This is your best bet if your height ranges from 12 to 18 inches. BMX experts who weigh more than 130 pounds and are taller than 140 centimetres should select this level of skill. A twenty-to-twenty-frame size Four inches is the height of the top tube in this category.

BMX Master can only be used by riders with a frame diameter of 20.5 to 21 inches. Only professional BMX riders that weigh more than 165 pounds are eligible for the BMX pro classification, which is reserved for individuals who compete on a regular basis. Over 20.5-inch frames are included in this group.

Do they make BMX bikes for adults?

BMX bikes are available for all ages, from toddlers to grandparents. It is common for BMX bikes to have 20-inch-diameter wheels and a 21-inch-wide frame. It’s important to examine the frame size and the wheel size while deciding on a BMX bike. It all boils down to how tall and heavy you are and what you want to accomplish in the end. The majority of cyclists can ride on wheels 20 inches in diameter. Larger frames and wheels, on the other hand, are available.

The Size Of The BMX Frame

BMX frames are available in a wide range of shapes, widths, and weights due to the wide variety of materials that go into their construction. Some forms are better suited to a particular discipline than others. This guide is written with the assumption that you are purchasing your first BMX bike and have no prior riding experience.

The frame size is the most important decision you’ll make when purchasing a bicycle. It’s not always a good idea to buy the first bike you fall in love with. Don’t panic, though; the work at hand is straightforward. Using your height, we’ll be able to determine the optimum frame size for you. We’ll be able to calculate the best top tube length for you as a result of this. For any case, chromoly is the best material. A little extra money may be required to get this, but it is more durable than normal hi-ten steel.

What are some safety precautions when riding a 20-inch BMX bike

  • You cannot ride a 20-inch BMX bike without safety gear like gloves, a helmet and knee and elbow pads. These items are all required by law.
  • In order to avoid becoming entangled in the handlebars or the frame of the BMX bike, riders must wear clothing that will not catch on them.
  • In addition to preventing cuts and scratches from tree branches, gravel on the ground, and contact with surfaces while executing tricks in midair, wearing long pants and sleeves can also aid.
  • Make sure your brakes are in functioning shape before you leave.

The Size Of The BMX Wheels

Once you’ve figured out the measurements of your bike frame, it’s time to talk about tyres.

Wheels are an important part of your vehicle’s overall performance. Wheels can be customised in terms of size, width, material, tyre size, rim size, and spoke count. All of these components have an impact on the quality, weight, and performance of your bike depending on what you intend to accomplish with it. Avoiding the more technical aspects for the purpose of brevity, we will keep it as simple as possible.

A 20-inch BMX wheel is considered the usual. Compared to a mountain bike or a road cycle, it has a much smaller wheel size. Wheels with a diameter of 24 inches are referred to as “cruisers.” They’re in their own division in the competition. Wheels with bigger diameters are most commonly used for dirt jumps and trials.

The 20-inch tyres should be used on the track, park, and street. 24-inch wheels improve stability and comfort when travelling long distances. Even if your primary goal is to use your bike for commuting to and from work, you may find them useful if you want better stability in the park and don’t intend to perform any unsafe manoeuvres. A bike with a 22-inch top tube and 24-inch wheels is a good option if you’re a big guy.

You can therefore choose between wide and narrow tyres, depending on your riding style. Because wide tyres are easier to land on and absorb all kinds of impacts, many freestyle riders choose them. This means you’ll probably have to slow down a bit when using these tyres.

Measuring the circumference of a racing wheel often involves using millimetres. Due to the need to move as quickly as possible, the wheels and tyres of racing bikes are thinner than in freestyle riding.


Please accept my warmest greetings whether you are just getting started or re-starting. Make a quick fix to your old bike at your local BMX shop, then get on the road. Having a concept of what you want to accomplish before acquiring a new bike is an excellent idea. The park is officially open for business. As the temperature rises, your skin will become red and your heart will race.

Take time to relax and have fun! That’s what BMX racing is all about.
