Specialized Hotwalk

Very attractive bike, and red (very important to DS) I'm not a cyclist myself, but DH and his brother are, and they say its very well made. DS had it just after his third birthday, and he was zooming around and balancing on it after his first hour in the park with it. Its also light enough that its not too bothersome to carry home when DS gets so tired his feet won't work.
Its not cheap, but DS loves it and uses it so much I think it was worth it.

We got the red one for our DD and it's a very smart looking bike. Extremely light weight aluminium frame, well made as all Specialized products are, comfy looking seat and little foot rests for once she's confident enough to do some cruising but not so big that she's likely to smack her ankles on it.

However, DD is an average sized 2.5 and can only just touch the floor with the seat on it's lowest setting. I'm hoping to try her on it again in a few months but for now it's unused in the garage. Not ideal as a 2nd birthday present unless you have a particularly tall child.
