I agree that a balance bike is good start rather than a bike with training wheels. DS went straight to a bike with pedals two weeks ago just before he turned 4. You would have to get one that suits her height though. Otherwise a trike if she is too little. DS had one of those when he was 2 or so and used it until he got the balance bike at 3 (which came with removable pedals). The trike was a eurotrike with a tip tray and had a removable handle.
