How to choose a bike helmet?

If you cycle more often you will know that one of the most important decisions we face is what helmet to choose to go with your bicycle. To know what to decide, you have to ask yourself a few questions. For example: How to know my helmet size? How is a bicycle helmet measured? What factors affect the safety? What models have the best ventilation? Which are most comfortable and what types of helmets are there?

There are a lot of questions to answer and we can help you get the answers, so you can pick the best helmet for you..

Helmet sizes and measures

Helmet sizes and measures

The size of your bike helmet must have the perfect fit for your head. That is why it is important that you know the size that best suits you. However, each manufacturer determines its own sizes, so sometimes to know the proper size of a bicycle helmet can be more complex than it seems at first.

You must use the correct measure of your head to choose the size of the helmet. For this you can follow these simple steps:

Sizes and measures
1. Measure your head

Take a tape measure and put it around the perimeter of your skull. Do it for the widest part, that is, by the area above the eyebrows. This way you will have the measure of the diameter in centimeters which will serve as a basis for deciding the most appropriate helmet.

Choose your size
2. Choose your size

Then, you must consult the drop-down list of sizes that appears in the product sheet of each helmet, and choose the size that corresponds to the perimeter of each head. For example size L (58-60cm) means for heads between 58 and 60cm of perimeter, and according to the manufacturer it is size L.

Final fit
3. Final fit

When you have found the right helmet to match your size, you can regulate it with the back ring and the adjustment belts that are usually in each model.

The best-selling helmets



There are many types of bike helmets available, but it is important you find one that fulfills its task. Safety is the main factor to take into account. Remember that it is the only security barrier you have in case of an accident. Therefore, you must choose a model that meets the best security certifications.

First of all, in order that it can be sold commercially – and used – it needs to be approved by a regulatory body. Being approved implies that the materials with which it is manufactured are made of hard plastic ABS or polycarbonate for the housing of the helmet. This is a harder material. In addition, helmets made with this material have worse ventilation due to lack of ventilation openings. The option of polycarbonate, therefore, is the most recommendable, because it ventilates better and absorb the impacts in a more appropriate way.

If you want to see more information about this topic, you may be interested to know that the standard of approval for bicycle helmets is the UNE-EN 1078. A label with those numbers appears in the approved helmets. This is very important. We recommend that you acquire a helmet with MIPS system so that, in case of impact, the effect of collision will be reduced at levels ranging by 40%.


MIPS stands for Multi-Directional Impact Protection System. It is a system of protection of multidirectional impacts. Thanks to a polycarbonate sheet separated from the outer part of the helmet, it allows (in case of impact) your head to rotate slightly inside the helmet so that the blow is not front. It is what happens with our skin around the head, it can move around the skull, saving us from internal damage. Therefore, the safest products you can find will be those that incorporate this system.



Ventilation is another essential factor. The foam lining retains heat and the head is one of the parts of the body by which excess temperature comes out when we exercise. The ventilation holes allow that area to refresh, so it is very necessary, both in warm and cold climates, in which it also helps eliminate moisture.

Good ventilation contributes to a correct aerodynamism, with which the friction of the air with the cyclist is reduced and its performance is improved. The most modern designs use ventilation channels inside the housing that allow the air to flow over the head of the cyclist.

Therefore, always double check the options you have. If you practice cycling usually, surely you know the sensation of heat accumulating in your head, sweat flowing and discomfort growing over your shoulders. So to make sure this does not happen and to not have the temptation to take off the main protection you have against possible blows, choose a model with which the hot air can come out easily.

Adjustment and clamping

Adjustment and clamping

To make sure the helmet doesn’t slide off your head, the helmet must offer you the possibility of adjusting it to adapt to your head. Most have some type of mechanism in the back, such as straps, to make sure you can easily adjust it. This way you will get your helmet perfectly placed and you won’t even realize that you’re wearing it.

Keep in mind that it should be well attached to your head, one or two fingers above your eyebrows. You must also have lateral straps in the form of a "V" with a slider. One of them must be ahead of the ears and the other behind. Normally, they have a lace device that keeps it well closed and that can be easily opened by just pressing.

This device is a buckle that is under the chin. This mechanism is very similar for many helmets. However, choose the one that is easier for you to use. For this you need to make sure you can enter not more than more than one or two fingers between the buckle and your chin.

Adjustment and clamping


Comfort lies in a good fit without excessive pressure on the face, chin or neck. The helmet must be light and leveled on your head, without any inclination. The front edge must be at one or two fingers above your eyebrows so that your front is well protected.

First of all, keep in mind that the helmet is an extension of your own body and that its main task is to protect you against head injuries in case you fall or suffer some kind of impact.

We recommend

If you are between two sizes, choose the smallest. If the helmet is bigger, you can use a cap to improve the helmet setting. However, to be sure of your choice, try it, adjust it and check how you feel with it. Encourage it side by side and back to front. If you move more than two fingers, you must adjust it better. You must also have good ventilation, which refreshes the interior when you have started to sweat but still keeps you aerodynamic.
