The small size BMX bikes have several benefits that we’ll review in the future. This article will discuss the reasons BMX bikes are small and provide you with the sizing guidelines to follow when purchasing that new BMX bike.
As a bonus, I will also address some questions regarding the topic.
Let’s get started!
Five reasons why BMX Bikes are so small
Below are five reasons BMX bikes aren’t big enough:
They have small Wheels
BBM bikes do have smaller wheels. They can behave and have wheels as small as 16 inches. But, the most popular BMX bike is available with 20-inch wheels. This is the standard and primary reason BMX bikes are small.
Although they might look strange even if you’re a tall adult, The smaller size of their wheels has the following advantages:
- Speed and acceleration are enhanced due to weight reduction
- Easier to maneuver
- More portable
They have small sprockets
BMX bikes are equipped with small, compact sprockets that offer several advantages. They are:
- The chain isn’t likely to break easily.
- The bike is stronger and is less bendable
This means you’re within the realm of performance. Smaller sprockets carry less weight, so you’ll have a lighter bike. This is a benefit in performing techniques.
They have small cranks.
Typically, BMX bikes come with a shorter length of cranks, approximately 145mm to around 190mm. But most freestyle riders would prefer a crank that is 165mm or less.
The more compact your crank is, the higher the clearance to ground, which can come in handy when doing tricks. In addition, the shorter cranks can also result in an easier bike and ensure that the pedals will be more close to the center of the bike, and you’ll be able to spot the pedals easily while thumping.
Short cranks are great for riding on flat land and are typical for racing BMX. They allow you to race BMX more quickly.
They have low seats.
As you are aware, BMX bikes come with low seats, which makes them smaller. However, the seat’s low position allows for better clearance and agility when performing tricks and stunts.
The lower seats make standing while pedaling much more accessible and let you quickly reach and grab the chair using your legs while performing the trick.
Was it First Designed to be used by children?
At first, BMX bikes were meant for children in the 6-17 age group. But they gradually became popular, and growing interest from adults. Their bikes, however, haven’t evolved significantly, so the bikes are small. This is the primary reason why BMX bikes are small.
Another thing to note is that BMX bikes have smaller components than other bikes. This makes them more suitable for children as they are easy to move and manage.
The positive side is that the maker has begun to produce a variety of frames and wheels that can meet the needs of adults.
They also give the flexibility to customize the product to suit your specific needs, particularly when you’re tall.
Benefits of BMX Bikes Being small
Here are some benefits of the smaller BMX size:
They are Lightweight
You’ll often see BMX bikes weighing 10 and 28 pounds, which is why they are light. Their light weight is because they do not have many moving parts, unlike other types of bikes.
The lower weight of the bike can help you navigate and control the bicycle. They are usually light and well-built, allowing you to do tricks and stunts easily.
They typically have Chromoly steel or aluminum frames. The aluminum frames are lighter, whereas the steel options weigh a little more.
Performs Well in High-Risk Tricks and Stunts
You can ask Pro BMX riders, and they’ll inform you that the less your bike is, the greater it will fly into the air when performing risky stunts.
In that mind, BMX bicycles excel at jumping higher than other bicycle models, which is why BMX is an Olympic sport.

The 20-inch freestyle BMX comes with a hi-ten steel frame, which makes it sturdy enough for high-risk moves and stunts. It’s an excellent choice for beginners as well as advanced cyclists.

Traveling with a smaller bike is more convenient than a big one. Right? The BMX bikes permit you to transport them wherever you want since they’re more mobile because of their lightweight.
Due to their compact dimensions, they are less difficult to maneuver and endure the most severe road crashes.
A more agile BMX can provide more ease of movement while making aerial and flatland tricks seamless. It also allows you to turn quickly, particularly on wet ground.
Small Bikes are Speedy
Since BMX bicycles are compact and light, they have smaller wheels and spokes.
This reduces friction more than larger wheels. This is why many Olympic BMX riders use alternatives with smaller wheels.
Also, you’ll require a BMX motorcycle with small wheels for riding in a crowded area. You might need to make quick stops due to its rapid acceleration and power.

The most important thing to consider when buying any bike is its size. The BMX makers are aware of this, which is why they offer eight sizes of bikes available.
