About 160 cyclists are killed every year in Britain and some 2,500 are seriously injured. More than 90pc of them are in collision with a motor vehicle. Roughly a quarter of those deaths and serious injuries involve children: so almost one child a week under the age of 15 is killed riding a bicycle in this country and about 12 a week are seriously injured. During the single month of September 2012, 305 children were injured cycling to school – more than 10 a day (children are more at risk in the first month of a new school year when many will be finding their way to a new school for the first time).
