Anyone had experience with these clowns my daughter attended one of the courses at her School I was surprised to hear that one of the instructors rejected my daughters bike on tyres adding that she would not be allowed to ride on the second day without them being changed. On inspecting her current tyres which I do regular basis I found nothing wrong with them apart from them starting to reach the end of their service life but by no means there yet. Rushing about I managed to find a set 24 x 1.85 with tubes for £51 at the local boutique bike shop. On the internet I could have done this for £30 but I did not wish to disappoint my daughter however if I had known about the officious health and safety aspects of the course I would have not put her on it. A lot of parents were told they would have to fix the kids bike before they could go out and a lot would not have been able to do it in time.
