Can anyone help me we are going to be getting a quest 88 dresden wheelchair bike for my 7 year old disabled daughter and i need to get her a helmet. The problem is that she has quite a wide head and a flat head at the back we have been to many local bike shops but with no success does anyone know of any specialist helmets or makers of bespoke helmets as we are running out of options. We may have to get a horse riding helmet made specially made which is going to cost me more than £500 . Can anyone HELP
