Looking for more of the best boys kids bikes?

We’ve put an in-depth guide together for that.

We have looked over 20 boys’ bikes to make sure you’re getting the best for your money. We looked at frames, safety, weight, and wheel size to make sure we’ve found the greatest products available to buy – you can see the full guide here which will be more relevant than the one you’re reading now.

What to look for when buying a BMX bike for a 12 year old?

Quality – Whenever budget is not a problem for you, always make sure you get the best quality in terms of everything. If you want a good frame, make sure it is high tensile steel or an aluminium frame. They will see you through many many years. Also make sure the tyres have a good grip and will not lose structural integrity in slightly difficult environmental conditions. It is easy to go for a bike that is cheap when it comes to price, but those are the ones that skimp on quality.

Customer satisfaction – Nothing is perfect. Hence, mistakes by any company are bound to happen. Not that it is a problem, but not being able to get a good and timely response from the company definitely is. Make sure you spend on a well-known and reputable company that gets in touch with you at the earliest whenever something goes south with the bike.

Saddle and Handlebars – These are the two very important aspects of a BMX bike since they are the two interfaces of interaction with the bike. You grip the handle all the time and the saddle is what you rest yourself on. Have a look out for good quality adjustable saddle that is comfortable to ride on, and good strong handlebars that are tall for the right posture. 


How is a BMX different from a regular bike?
The primary differences between a regular bike and a BMX are in terms of design. A BMX is built for sprint around a short track with bumps.

Do BMX bikes have shocks?
The only shocks found on a BMX bike are the legs and arms of the rider. Hence, you should be careful wile riding.

Does BMX build muscle?
Of course, it does! All exercises build muscles. And BMX is not only great for muscle building, but also helps in improving a good cardio-vascular flow and a strong immune system.

What is a BMX bike good for?
A BMX bike is great for racing and basically thrashing around. They are lightweight which makes them easy to transport and life to do tricks on.


The companies we looked at today knocked it out of the park with their products. A lot of them had very little to almost no cons at all. All of them had a tensile steel frame or an aluminium frame so durability was not an issue.

The bikes had adjustable saddles which were comfortable to ride on for hours, and the tyres also had great grip for better traction on the road.

BMX is a lovely sport loved by everyone. It brings the thrill from adrenaline and good muscle formation. It is a great way to get your 12-year-old started in the amazing world of cycling.

No matter which bike you choose from the list we looked at today, you will not be disappointed.
