We are still working on it at 5. We did the balance bike and that went great, but then she outgrew it and we got a new bike which is relatively lightweight but still heavier than the balance bike, and the weight stressed her out. We wound up putting the training wheels on because it was the only way to convince her to use the new bike. So we're going that route which I know will take longer, but I think it's important kids feel comfortable an not rushed with this one, because I want her to enjoy riding the bike and not view it as a chore.
