These are some of the UK's biggest cycling questions. Can you answer them?

The correct answer is no. It is not illegal to cycle without a helmet, regardless of how old you are.

A spokesperson for RoSPA (The Royal Society for the Prevention of Accidents) told Other Side of the Story: “There is currently no law in the UK requiring cyclists to wear a cycle helmet, regardless of their age.

“This means it is not illegal for either adults or children to cycle without a helmet. However, Rule 59 of the Highway Code advises that cyclists should wear a cycle helmet that conforms to current regulations, is the correct size and is securely fastened. While this is guidance rather than a legal requirement, RoSPA encourages cyclists to wear a properly fitted helmet.”

The spokesperson added that helmets are designed to reduce the risk of head injuries if someone falls from their bike - or to make any head injuries less serious. RoSPA also says they should be seen as one element of road safety, which includes safe behaviour from the cyclist and responsible driving from motorists.

The brain injury charity Headway believes helmets should be compulsory for all child cyclists and that anyone, however old they are, who gets on a bike should wear one.

The NHS says that cycling has huge benefits for your health. Not just in physical exercise but also for your wellbeing.

Cycling UK, the country's oldest cycling charity, also says that regular cycling can reduce our risk of developing serious illnesses such as heart disease, type 2 diabetes and obsesity.

If you're old enough to join a gym, but the membership fees are putting you off, both the NHS and Cycling UK recommend cycling as a cheaper alternative. It's a one-off purchase - although you will need to make sure your bike is properly maintained - and the scenery seen from a bike can always be different, instead of the same gym walls!

Cycling can help you feel less stressful and also reduce anxiety. It's also a good social activity - something fun to do with your friends on a sunny day!

Even if you only cycle a few times a year with barely a bump, it’s always worth checking your cycling helmet as parts of them can deteriorate as they age.

The RoSPA spokesperson explained: “Helmets should always be replaced after a crash if there is any possibility that the protective foam has been damaged, even if no damage is visible externally.

“Manufacturers' recommendations vary, but many suggest replacing helmets after several years of normal use because materials such as the foam liner, shell and straps can deteriorate over time. Cyclists should regularly inspect their helmet for cracks, damage or signs of wear and replace it if they have concerns about its condition.”
