Glide Bike:

Glide Bikes created the original balance bike. I've watched my own son learn on a balance bike since he was barely walking. It's given him such a feeling of independence and confidence. And when he's ready to transition to a regular bike. he should be able to do so without training wheels. From as young as 18 months through ages 10 and up there's a Glide Bike for your kid.
