Thinking of buying my little lad one of these for xmas and wondering if anyone has any experience of them..? 
  They say '6+ only' on the bike but it doesnt look any bigger than the electric one he has at the moment..? (my son is 4 in April, but quite tall for his age ) 
 Also..would be looking (ahem) to piggyback with him until he learns to handle it himself..not that I would enjoy that as Im sure you realise 
 
  Any advice/feedback appreciated ! 
 Cheers
 Nat 
 P.S Please dont think im flash/loaded..im only buying it with all the cash ive generated from selling me duke bits to you all you lovely people !!
