How To Choose The Best BMX Bike For Your Kid

BMX stands for Bicycle Motocross, and it’s the kind of bike used for stunts and racing. If you’d just think about that for a little moment, you’ll probably realize that finding a BMX bike for your kid is almost synonymous with giving them the key to a risky ride.

But nah, many kids use BMX bikes for more “practical” purposes, such as getting themselves to school. Still, once they got the bike, you can’t prevent them from seeing other kids using the BMX to toss themselves into the air.

That said, you can always limit the risks by choosing the most appropriate BMX for your kid. And the safest, for that matter.

For that to happen, you’ll probably be obligated to check on a few factors, such as the size and weight of the bike. So why don’t we get started with that?

Check The Size Of The Bike 

First up is the size. Here’s a common-sense idea: you need to find a bike that matches your kid’s height. The more important question is, how would you know?

I know how to answer that in a straightforward manner, and that’s through a simple table down below. But before I get you looking at the table, let me discuss a few terms.

  • Frame. It’s the bicycle’s main body, holding all the other parts together. 
  • Top Tube. This one’s the topmost tube of the frame. The longer it is, the larger the frame, and the larger the bike.
  • Wheel. Of course, we know what wheels are. But wheel size is the primary factor that determines a bike’s overall height — apart from the frame size.

Size Guide

Frame SizeTop Tube LengthWheel SizeAge RangeRider Height
Mini16″ – 17.5″20 x 1 1/8″ tires4 to 6 years4’0” – 4’6”(122 – 142 cm)
Junior17″ – 18.5″20 x 1 3/8″ tires6 to 9 years4’4” – 4’10”(137 – 149 cm)
Expert18.5″ – 19.5″20 x 1.5-1.75″ tires9 to 13 years4’8” – 5’4”(147 – 163 cm)
Pro20″ – 20.5″20 x 1.75-2.2″ tires12 years and up5’4” – 5’10”(163 – 181 cm)

So, the table above says it all.

Of course, there are many other size variants (Micro, XL, and XXL), but let’s keep things simple and easy to understand for now.

Just look up the age of your kid and pick the corresponding BMX size. Better yet, check with your kid’s height since it would be the more appropriate factor.

Check The Weight Of The Bike

A bike’s weight can change everything, I mean the overall riding experience. 

Now that sounds like typical propaganda. Well, of course, there’s a general notion that lightweight feels faster and easier.

Anyway, a lighter bike would certainly be easier to pull around. Your kid could go faster on it without spending too much energy. And it’s probably a lot easier to control — but honestly, it depends on who you’re talking to.

Just note for now that lightweight bikes are generally more expensive.

On the other hand, you could spend a long time getting used to a heavier bike. If you stick around it, you can build great muscles (I mean your kid). 

Apparently, some lightweight bikes may not be that durable (we’ll talk more about this later).

So, I guess my advice would go this way: start off with a heavier (or moderately heavy) bike. When your kid has mastered cycling’s basics, plus a few tricks, stunts, and bunny hops, you can begin investing in a lightweight bike.

Consider The Child’s Skill Level

I’ve hinted on this in my closing paragraph in the previous section. What I want to add here is that you need to check if a BMX bike has parts built for its rider’s safety. Especially if your child is still a beginner.

In addition, you may want to add some safety gear your child can use for training.

Safety First, Safety Gears

If you don’t have any or all of the following yet, be sure to buy them along with the BMX bike.

  • Helmet
  • Elbow pads
  • Knee pads
  • Gloves
  • Neck guards
  • Goggles
  • BMX pants
  • BMX jersey

Just make sure everything fits right. Too tight or too big means being much more prone to injury. Also, you can prepare a gear bag (to put everything else into), plus a first aid kit.

Check The Durability Of The Bike

How durable a bike is would depend heavily on its parts and how the bike is used. For starters, look for quality bike frames, wheels, and breaks.

Stunt riders usually prefer steel frames since they are highly resistant to fatigue.

Meanwhile, racers like the more lightweight aluminum frames.


If your kid is already on the elite team of riders, you may want to gift them with a carbon-fiber-framed BMX bike. It could last a lifetime.

Meanwhile, a BMX wheel needs to be light enough to propel the rider further and even faster, but at the same time be heavy-duty enough to endure the impact of landing.

BMX brakes, on the other hand, need to have stiffer springs and softer compound pads for an excellent overall performance.

This bike’s main frame is made of aluminum, which has been hydroformed to shape a unibody that can stand better against stress.

You might expect this bike to be lightweight, but it’s not. It’s most likely because of its wheels, which are made of steel.

Note that this bike is suitable even for girls who simply like to enjoy a smooth ride (and not necessarily do stunts). In this context, I’d like to highlight the enclosed chains, which of course can help a lot with the safety of the rider. Yep, it can protect your kids’ legs from getting hurt.

Anyway, that makes the bike resistant to strain, breakage, or deformation.
