I've been devouring some good biking info from Sheldon Brown's site, and he's of the opinion that the earlier the better for youngsters to start bike riding--even saying that at 2 1/2 the kid will be ready!
My son is 4 and my daughter will be 3 in a month, and I thought it would make the perfect Christmas gift to get them both a bicycle. I just don't want to rush them and have them fall and be scared of it. I'm pretty sure my son can handle it, but it will be a travesty to my daughter if I don't get her a bike as well. She wants to do everything he does (and does a great job at it too!)
Anyone actually do this in practice and have luck with it?
