This helmet features an in-mold outer shell with reinforced Polycarbonate with an EPS inner shell for impact protection. The helmet does look a bit wide and bulky, but it’s actually quite light and very comfortable.

One of the advantages of this Melon helmet is the excellent ventilation system. It consists of 12 ergonomic ventilation holes which are connected to airflow channels.

Furthermore, removable Coolmax pads are placed on the inside of the helmet. They are made of a soft foam so they can absorb sweat efficiently. They really make the helmet feel light and airy. The pads are also machine washable which is very convenient.

What we like about Melon helmets is the functionality and attention to detail. Every little part of this helmet has its purpose and works perfectly. The adjustable chin straps come with a magnetic buckle which makes buckling up incredibly easy. There is a soft pad that goes under the chin for added comfort and locking sliders hold the fit in place. A spin dial at the rear allows you to adjust the fit of the helmet.

How to Choose The Best Bike Helmet for Kids


Even though most kids’ helmets come with an adjustment system, you won’t be able to make it fit perfectly if it’s not the right size. What you need to do in order to determine your child’s helmet size is measure their head circumference. You can use a cloth measuring tape or just a piece of string in case you don’t have one at hand. Place the tape across the child’s forehead, just above the eyebrows, and wrap the tape all around their head. Once you have measured the head circumference, compare it to the manufacturer’s sizing guide in order to find the right size.


The two most common types of kids’ helmets are hardshell and in-mold. Both types adhere to safety standards and provide adequate protection, but bike helmets with in-mold construction have some advantages.

On hardshell helmets, the foam core is glued to the plastic outer shell of the helmet. With in-mold helmets, on the other hand, the foam filling is fused together with the outer shell. This results in increased durability and lighter weight. In-mold helmets also typically have more air vents.

If you want a helmet with the highest possible level of safety, you might want to look for one with Multi-directional Impact Protection System (MIPS). MIPS is essentially a thin liner inside the helmet that allows the outer shell of the helmet to rotate a few millimeter upon impact. This reduces the rotational force and helps protect the head from angled impact.

Adjustment System

A good fit is extremely important with helmets. If a helmet doesn’t fit right, it might not be completely safe. The helmet has to stay in place during a crash in order to protect the head, so it needs to fit snugly.

All of the helmets on our list have an internal adjustment system that allows the helmet to conform to your child’s head. Head shapes of children vary greatly, so an internal adjustment system is essential for achieving a good fit.

The chin strap also plays a very important in keeping the helmet in the right position. The chin straps should form a V shape just below the ear. Some models, like the Melon helmet we reviewed, have locking sliders which help keep the straps in place. Many helmets don’t have locking sliders, but this is not a big problem. You’ll just need to adjust them more often.


A helmet with more air vent will logically provide better airflow. Because of this, traditional bicycle helmets usually have better ventilation than skate-style helmets. However, Melon Decent Double Urban Active Helmet is a skate-style helmet, but it has a system of air channels and absorbent inside padding which make it one of the best in terms of breathability.

Final Verdict

As we have already mentioned, often the biggest problem with helmets is getting the kids to actually wear them. For this reason, always take your child’s preferences into account and go for a model your child likes. However, a kids’ bike helmet also needs to be safe. We love the Melon Decent Double Urban Active Helmet because it’s stylish, well-constructed, breathable, and functional. However, if you’re on a tight budget the Scamp helmet from Giro will do the job just as well.

On the other hand, if you are looking for a kids’ bike helmet equipped with MIPS, Bell Sidetrack MIPS Youth Helmet is a great choice. Finally, we hope our guide has helped you find the best bike helmet for kids and remember, always wear a helmet!
