Beginner’s guide to bike helmets

How to choose a bicycle helmet and look after it - and our pick of what's out there

Bike helmets aren’t compulsory in most countries – except for racing – but a good-fitting lid can help protect your head when you’re commuting by bike or out for a weekend ride.


When choosing a bike helmet it’s essential that it’s a perfect fit – snug without being tight or pinching. When the retention system is properly adjusted the helmet should stay in place if you shake your head quite hard. A helmet that doesn’t fit well won’t provide as much protection as one that does because your head will still be able to move around inside it in the event of a crash.

The shape of the inside of a helmet differs between manufacturers, so it’s important to try lots on. Most people find that their head shape – be it rounder or more oval – corresponds to one or two brands.

It’s also good to try on helmets in your local bike shop and get someone to help you fit them properly. Remember that you must do up the straps – if you don’t then the lid won’t protect you.

A well-looked-after helmet should last for about eight years. You can clean it with mild detergent or simply soap and water. Store it in a dry, well-ventilated place when not in use and avoid heat sources such as radiators and airing cupboards.
