DS just tried some bikes at Halfords. 20 inch too small, 24 too big and I have looked online and nowhere does a 22!
Would you get him a cheap one for now, or leave it a bit? His current bike is wayyyyyy too small. Not really rideable for him but with it approaching winter, I'm not sure how much he would use it anyway.
I don't think he will be big enough for 24 by xmas either.
