Like them or not, bike helmets are here to stay. Whilst the law doesn't (yet) insist on their use, bike helmets are deemed the number one accessory for every cyclist. If you race or take part in any organised events then the majority will insist on a helmet, and as a commuter, if you don't wear one then people are likely to mention it or even deem it the reason for you having an accident. And like everything to do with cycling there is wide variation in type, design, colour and cost.
All helmets sold on Pedal Pedal are certified and labelled with a European CE EN1078 standard - which means that they are up to the standard required by EU countries.
