We’re aware of the argument against cycle helmets (cyclists killed in road accidents, tragically, die of injuries other than head trauma, self-consciousness dissuades some from becoming cyclists, etc), but given the choice of riding with a helmet or without, we know which we choose every time.

Not convinced? Try this simple experiment: sit in the passenger seat of a car, ask the driver to accelerate to anything between 20mph and 40mph, and, having done so, to push you through the open door.

Before he does, you can remove your cycle helmet if it makes you feel safer. Any takers? Thought not.

All helmets sold in the UK should meet the European Union standard, meaning more expensive units are not necessarily more robust, but typically lighter and better ventilated.

Look for absorbent pads, a tactile adjustment dial at the rear or on top of the helmet to tighten or loosen the cradle that holds it to your head, and easily adjustable straps.
