21 inch wheels seem an odd size but you can get kids racers with smaller wheels, a mate of mine had one. I wouldn't touch one personally as you'll only get crappy parts. You can get small road bikes with normal sized wheels but what may suit you better is a small light mountain bike set up (all rigid) as a road going machine (skinny tyres etc..).
