14 or 16 inch bike for 4.5 year old?

[lunavix]

He's I'd say average height (maybe 105-110cm??) but I'd like it to last, while at the same time he needs to be able to ride it!

Needs to be really, ahem, 'cool' and (for me) a bargain too

My 4 year old has a 16 and fits him perfectly.

I recommend the Ridgeback, it is a proper bike rather than a 'toy' one, DS got the 16 inch one when he was 4 and it was fine.

Bugger, sorry, DS doesn't have a pale green figaro, obviously! I meant to link to this!!

Dd2 got a 16 inch for her 5th birthday and could only just reach the floor when it was set at its very lowest. She is a bit of a short-arse though ...

I would check first that he can reach the floor before buying.
