Things to Consider Before Buying Mongoose Bike

Even though all bikes roll their wheels on the road, when it’s about BMX bikes, there are certain characteristics that differentiate this type from others

Frame and Fork Material

Both the frame and fork need to be made of durable and lightweight material such as aluminum.

There are Hi-tensile aluminum-made frames that are used in bikes. This material is pretty lightweight and cheaper as well.

Chromo steel frames are a bit expensive. If you want a bike with an utmost lightweight and durable frame, go for carbon fiber frames. These are more expensive ones.

Wheel Size

BMX bikes come with different wheel sizes. 20 inches is considered as the standard size, which is for more skilled riders. Beginners suit best with 16 to 18 inches wheels; this is for kids and teenagers.

However, there are also 22-inch and 24-inch wheel sizes available in the market. These are for BMX dirt racing and jumping. Larger ones are for taller pro BMX riders.

Rim Size

The standard rim size for freestyle BMX bikes is 32mm. If you prefer to put a bit more pressure and the rim has to endure more impact than usual, consider getting a 36mm wider one.

There are single, double, and triple-walled aluminum made rims to provide necessary structural support depending on the strength and weight.


Both the spoke count and rim size has to do with the overall strength of the wheelset. For most riders, 36 spokes will be enough to go with a freestyle BMX ride. Pro and advanced riders require up to 48 spokes on the wheels.


If you mostly ride on parks and smooth surfaces, wider tires are recommended. Tires that can withstand up to 110 psi, roll faster while giving protection to the rim as well.

Low-pressure tires provide more grip for dirt jumpers. 2.1 inches wider tires will provide better stability in this case

Ball Bearings

Open cage ball bearings are good for entry-level bikes, as they cost much less. Sealed or cartridge bearings, on the other hand, are more expensive and can endure tough conditions.

Frequently Asked Questions

Do I need to assemble the BMX bike I ordered?

Yes, you need to assemble the bike yourself. There will be instructions from the manufacturer about how to do it.

When do I need 20 inches tires?

If you do well with 18 inches tires, you can upgrade them without any issue. Beginners can also start with 20 inches as per their ability to handle the bike.

What age is a 20 inches BMX bike for?

Being the standard bike size, kids over 8 years and teenagers are good to go with a 20 inches bike without much trouble.

What does make a BMX bike different from a regular bike?

Unlike regular road and mountain bikes, BMX bikes are made for sprinting around short man-made tracks. These are not for long-distance, natural, and rough terrains.

Is BMX safe for kids?

Even though BMX biking is among the most dangerous sports, it only refers to adults who
perform risky tricks and stunts. If the kids use a BMX bike for riding on a road, in the yard, and not doing any tricks, they are safe.

Final Words

Hopefully, these Mongoose BMX bike guide helped you out to choose a suitable bike, whether it’s for kids or teenagers.
