This video of a mountain biker going over his handlebars, landing on his head and being knocked unconscious in the Surrey Hills was sent to Eagle Radio to highlight the effectiveness of cycle helmets. The uploader says the helmet took the main impact of the fall and without it the cyclist would have sustained far more severe injuries.
As it was, the man involved, Andy, was taken to hospital, where he was given the all clear. He was back in work two days’ later.
Be warned that the video does contain some images which may be upsetting for some people.
Tim Rowsell, who recorded the video on his GoPro, said:
"It doesn't take much to get quite a severe head injury and that's why I want people to see it. If you wear a helmet it can save your life and I genuinely believe that he would have been in a lot worse a state if he hadn't been wearing a helmet at the time.
"He was incredibly lucky and you can see at the end of the video that the helmet took the main impact and really was quite badly damaged. It was an old helmet, which he hadn't used for a couple of years, but it did the job."
Organisations such as CTC, the national cycling charity, are against making cycle helmets mandatory, arguing that cycling should be promoted as a safe, normal and enjoyable transport and leisure activity which anyone can do, with or without a helmet.
CTC points out that whether or not it is a good idea to wear a helmet may depend on both the rider and the type of cycling they are doing.
