I want a pocket bike. I have an 18 month old son. He is as good an excuse as any to get one. Any help as to model and or dealer would be appriciated. Also are there sizes of bikes? I think I remember hearing that there was like a pocket and a pocket+ size but I can't find anything to confirm that. Thanks, Rick (& my son C.J.) Once his feet touch he's rolling! P.S. anyone hotrod one up as a race toy...I was thinking of tinkering one up.
