We have a lovely Chris Hoy childs's Bonaly bike to sell. Our son used it between the ages of around 8-12. It is a 24 inch wheel inc tyre - the tyres are quite thick. It is in good condition, very sturdy and has shimano gears. I would advise anyone interested to bring their child with them to try it out to make sure it is the right size. We are on Sydney Road. It's a great bike - we were very happy with it but he has just grown out of it. Retails at £450.
