Hey Biker , You might ask, “How to Choose a Bike Helmet ?

When we buy a cycling helmet, we often base our purchase decisions on aesthetics, color, and comfort.

Are there other factors that we should consider when choosing which helmet is the most appropriate for us? 

Choosing a model within the range of bicycle helmets is a particularly sensitive issue since it is an essential safety element. The bicycle world is full of marketing and terminology that often misleads us to choose the most suitable bicycle components or accessories.

If we add to this that when choosing a bike helmet, we must consider aerodynamics, ventilation, or comfort, things get even more complicated.

In this article, we want to shed light on the matter and expose the aspects that you should consider to help you when buying the bicycle helmet that best suits your needs.

Types of bicycle helmets

There are different types of helmets for the various disciplines of cycling. However, in terms of urban cycling and cycling tourism, three types can work for you according to your needs and style.

Types of bicycle helmets

Recreational bike helmets

These helmets are not designed to be the lightest or most aerodynamic, but rather to look good. Some models usually incorporate visors to protect from the sun and generally do not have much ventilation since they are intended to be used on relatively quiet tours.

Cycling Helmet

Mountain helmets

Helmets designed for mountain biking have ventilation that works very well even at low speeds. These types of helmets offer more excellent protection on the neck.

Most incorporate visors to protect from the sun, which can be easily removed and put on in many cases. The fit on mountain helmets is very good at preventing movement when pedaling on uneven terrain.

There are Full-face models with chin protection preferred by those who practice downhill and other disciplines that require more security.

Mountain helmets

Road helmets

These helmets are characterized by being light, with excellent ventilation, and by their aerodynamic design. In general, these helmets do not have visors since the extra grams are not the most desirable and can also obstruct the vision when pedaling with the body inclined forward, typical in road bikes.

How to Choose a Bike Helmet For beginners

1. Hull construction

The vast majority of helmets, mainly mountain and road helmets, are manufactured using a method known as in-mold. This process consists of fusing the helmet’s shell with the inner lining without using glue, which helps to make light and resistant helmets.

The shell’s function, usually made of plastic, is to hold the helmet liner together when it is hit. Also, it offers protection against punctures and helps the helmet slide on the road when it falls.

On the other hand, the covering, generally made of expanded polystyrene foam, can dissipate the impact energy.

2. Main characteristics of the helmet

Ventilation – Ventilation helps keep your head cool by allowing air circulation while on the go. When looking for a bike helmet, it is essential to consider the conditions you will face on your journeys and choose one with adequate ventilation.

Adjustable straps – when looking for a helmet, make sure that its straps can be adjusted without problems and that the buckle is easy to fasten and unfasten.

Visor – as we mentioned previously, not all helmets have a bill, and others give you the option of putting it on and taking it off according to your preference. Some prefer a little protection from the sun.

3. Proper helmet size

To achieve an optimal comfort and safety level, it is necessary to find a helmet of the correct size. To determine the size you need, you can measure your head’s circumference with a tape measure.

Alternatively, you can use a piece of yarn or ribbon to get the circumference of your head and measure it with a ruler. This measurement will give you a good starting point to start testing different helmets.

4. Proper helmet fit

The important thing when trying on a helmet is that it fits your head comfortably and that it does not sway from side to side.

Depending on the model, you may be able to adjust it a bit using different pads (included with the helmet) or with its adjustment system (in more sophisticated models).

Another critical point is to take care that the helmet is at a suitable height, approximately two fingers from your eyebrows. It is essential to maintain good visibility and protect your forehead when falling.

Another point that you should consider is the adjustment of the straps. These should form a “V” under your ears without hurting you. The buckle’s adjustment should be such that when you open your mouth (with the buckle fastened), the helmet presses slightly on the top of your head.

  • If the straps are too tight, they will be uncomfortable
  • If the straps are too loose, the helmet will move out of place

5. Find a helmet that suits your style

Some think that bicycle helmets do not look so good. It is always a good idea to look for a helmet that suits your style and feel comfortable. Today it is possible to find models for all tastes. If you like it, it will make you want to use it all the time!

When to replace your Bike helmet

If you suffered a considerable impact, it is advisable to replace the helmet with a new one, even if there is no apparent damage.

Experts recommend changing your helmet every five years as UV rays and pollution can deteriorate some of the helmet’s materials.

How To Care For Your Bicycle Helmet?

  • Do not store the case in hot places or near heat sources.
  • Do not use solvents to clean your helmet. A damp cloth and soap are more than enough. The pads can be removed and washed separately.
  • Avoid lending your helmet. It is always good to know the exact use and impacts to which it may have been exposed.

Examples of bike helmets

Bern Helmet

Bell helmet


Bell is a brand founded in 1954, first manufacturing helmets for motorsports, but soon started with helmets for other sports. Today it is one of the most famous bicycle helmet brands, and they have options for all budgets and branches of cycling.

What are cycling helmets made of?

Most helmets consist of two layers. The first is an interior made of EPS expanded polystyrene and serves to absorb shocks in the event of an accident. Depending on its density, it will absorb impacts better or worse.

The second layer is the outer protective shell, usually mostly ABS plastic or polypropylene, although there are also carbon ones.

These two layers in the lower ranges of helmets are usually glued. However, in mid-range and high-end helmets, they melt into the polystyrene injection phase through In-Mold technology, giving it more excellent impact resistance and more extraordinary lightness.

Helmets with MIPS technology

MIPS is a multidirectional impact protection system. What it does is protect the brain from the creep rotation that occurs in a fall.

This is achieved with an inner shell independent of the helmet structure, in such a way that if there is a fall and the helmet is hit. Simultaneously, the outer part absorbs the blow and the inertia of the speed. The inner one has a specific independent movement that reduces the abruptness of the initial impact.

This protection system is shared among brands, but they implement it in their helmets in different ways.

ANGi technology helmets

It is a sensor patented by Specialized that connects with our smartphone, and in the event of a fall, if it detects a crash, it will send an alert to your selected contacts with the last known GPS coordinates and a message requesting help.

This system also connects with Strava. The only downside is that it forces us to have the mobile battery charged and check if there is any point on our route to losing coverage.
