Colin , don't ask for two much ,at 16 both of mine ,4 years apart , were typical teenagers ie thoughtless, mess machines (Son and Daughter ) but slowly with a bit of love,care & patience and above all time they begin to put things in perspective and now I have 2 great friends as well as 2 smashing kids who I proud of, but neither have any love for bikes still you can't have everything ,hope you get the wheel sorted, regards BobH
