BMX bikes come in several shapes and sizes made according to the rider’s height, age, and weight. Most BMX bike sizes are accustomed to kid sizes which might lead you to assume that they can’t hold too much weight. Let’s find out how much weight a BMX bike can really take. 

How much weight can a BMX bike hold?

There is no standard weight that a BMX bike can hold. BMX bikes have no weight limit. But there are estimations of the rider’s weight for every BMX bike size. They are built to withstand high amount of pressure for performing stunts and tricks. Generally, most bikes cannot hold more than 300 pounds. 

Do BMX bikes have a weight limit? 

There is no weight limit for a BMX bike. It is built for heavy pressure so it doesn’t matter how much you weigh. However, there is a suggested weight limit for smaller BMX bike sizes.

There is a height concern as well. Obviously, a 6-foot professional rider won’t be able to ride a BMX bike built for a 5-year-old kid. The design, frame and wheel sizes are different. They are built differently to offer sizes for different types of people. 

So what happens if you go more than the suggested weight limit? You won’t notice the consequences right away but it will damage the vehicle eventually. For safety reasons, don’t try it! 

How much weight can a 20-inch BMX bike hold?

That is the standard frame and wheel size for a BMX bike. The suggested rider weight for a BMX bike of 20 inches is 100 to 130 pounds.

They are made for riders who are 163 cm to 170 cm in height. It can hold more than 130 pounds, there is no doubt about it. But it won’t be as comfortable for the rider. For convenience, go for larger sizes. 

What makes BMX bikes handle any rider’s weight?

It is the elements of a BMX bike and its design that makes it handle any rider’s weight. 

The Frame:

The material of BMX bike frames and its geometry is what makes it able to handle a rider’s weight. They are made out of steel or CroMo. CroMo is short for Chromoly 4130 which is alloyed steel. Aluminum and CroMo frames make the weight of the bike less. But steel ones tend to be heavier which makes them stronger and able to hold heavy riders.

The design of the frame also allows it to perform stunts that require a lot of pressure. This enables it to withstand more weight as well. 

Spokes:

Before purchasing a BMX bike, you should know the spoke count. The higher the number of spokes, the greater the strength and weight of the wheel.

Most average BMX bikes have a 36 spoke wheel but heavier riders go up to 48 spokes. It doesn’t matter what the rider’s weight is, even if you have a high spoke count. 

Rims:

BMX bikes have 3 types of rims. Single, double, and triple. Double-walled and triple-walled rims are stronger and they enhance their constructional strength. 

Tires:

The impact absorption of your wheel depends on the width of the tire. If the width of the tire is high then it allows greater impact absorption.

The type of tire you choose will affect your speed and grip. Some BMX tires can take pressures up to 120 pounds per square inch. It protects your rim when you are under load. 

Tyres are easily changeable so you can change them if it does not work well for you.

Forks: 

Just like Frames, they are also made with steel or CroMo. This makes them more resistant to heavy force and they can withstand large impacts. 

Cranks:

BMX cranks are of 3 types, one-piece, two-piece and three-piece units. Three-piece cranks are the strongest. A two-piece and three-piece unit should be enough to take the pressure of the rider’s weight.

The size of the crank is mostly dependent on the rider’s height. They vary from 145 mm to 190 mm. The most popular crank size is 165 mm. 

The Wheel: 

Wider bike wheels hold more weight and some BMX bike wheels should work fine till about 350 pounds as long as they are of good quality.

You can also customize your own BMX wheel. Make sure the rims are double-walled and strong. Also, more spokes can allow you to put up more weight.
