How to Choose Your Bike Helmet



Like me, you might remember the era of “hairnet” helmets or the complete absence of helmets in competitions. The aim of this article is to talk about head protection and its importance for you, whatever kind of cycling you do.

In this article, we will cover the following topics:


1. Why Wear A Bike Helmet

1. Why Wear A Bike Helmet.

Even though the number of cyclists killed on the roads has been decreasing over the last twenty years, there are still quite a few number of recorded injuries due to bike accidents.

Should you fall, the part of your body that is most likely to be hit is your head. It’s also your head that tends to suffer the most severe injuries.

Designed to limit impacts, helmets absorb the force of the impact up to their resistance limit. If the power of the impact exceeds this limit, the helmet will crumple. The way it absorbs the shockwaves is a bit like the role of a car airbag: its main aim is to protect your head from direct impacts. It also protects mountain bike from low-hanging branches or flying rocks.

In addition to Australia, wearing a helmet is compulsory in other countries (Finland, Netherlands, Turkey, etc.). There are also certain criteria (age, weather conditions, rural or urban area, etc.) that make it a requirement on roads in Canada, Czech Republic and Spain, for example. Before setting out on your bike in a foreign country, read up on the local laws about bike helmets.



2. How To Choose A Bike Helmet

According To Your Type Of Cycling

There are different models for the different kinds of cycling. For downhill MTB or BMX, go for a full-face helmet.

For MTB, you might want one with a visor. On the road, opt for a helmet with as many vents as possible for summer and with small nets to stop insects from getting inside.


According To Your Taste

Nowadays you can get helmets to suit all tastes and budgets. So go for whatever takes your fancy. You don’t need to spend a fortune to stay safe and stylish!



3. Helmets Constituents

A bike helmet is composed of three parts. The outer part (the shell) covers a polystyrene cap whose job is to absorb the impact in order to protect you. There is also a layer of foam inside that helps you adjust it to the right size and makes it more comfortable to wear.


4. Helmet Sizes


The size of your helmet can be measured in two ways: with a standard size or with your head measurement. To give you a better idea, here is a size guide for the B’TWIN product range.

Size XS - < 47 cm head size
Size S - 47-52 cm head size
Size M - 52-57 cm head size
Size L - 57-61 cm head size
Size XL- 61 cm head size



5. Warning


Safety Standards

Check that the helmet you are buying complies with the AS/NZS standard. The AS/NZS mark guarantees that tests have been carried out to check the helmet’s resistance. To see whether it complies with this standard, check inside the helmet.


Fixing Cameras On Your Helmet

A lot of cyclists are now fixing a small camera to the top of their helmet so that they can relive their rides or share them on social networks. I do not recommend doing this for two main reasons

This additional weight can cause excess strain and lead to neck pain. When you get on your bike, you need to listen to all of your senses and pay attention to any slight pain so that you can adjust your position. This accessory distorts your judgement, especially if it is not fixed in the centre (side or front/back)

If you hit your head, you won’t be effectively protected. In fact, your helmet is designed to cushion you from impacts with the ground. It absorbs the impact and then crumples to protect your skull. But it is not designed to withstand the pressure of the ground against a very impact-resistant solid object. The camera could tear your helmet and come into contact with your head. Michael Schumacher’s recent low-speed skiing fall is proof of this
