What size bike helmet do I need?
It is a fact that a bicycle helmet provides safety. Wearing a helmet during a bike ride prevents permanent damage to your head. The risk of head and brain injuries is reduced from 63 to 88%.
However, a helmet can only provide safety when it fits your head properly. Avoid wearing a helmet that is too big and sits too loosely. Conversely, a helmet that is too small will sit too high on your head. When the helmet fits correctly, you should not feel it, ensuring a comfortable ride with the helmet on. Helmets are available in various sizes, so be sure to choose the right size when purchasing a new one.
Please note! It is possible that your head size in centimeters falls within the range of two helmet sizes. For example, if your head size is 55 cm, you could fit both a helmet size 'S' and 'M'. In this case, you have the option to choose a slightly smaller or larger bicycle helmet. If you regularly wear a cap or hat under your helmet, we recommend selecting the larger helmet size.
