BELSIZE 16-inch Belt-Driven Kids' Bike

This is a premium bicycle at a very competitive price. The relatively light weight of this bike compared to other bicycles will result in more time that your children spend riding due to less fatigue from wrestling with heavier bicycles. Additionally, the light weight will result in a much easier transition from a balance bike and/or bicycle with training wheels to a two wheel bike. As a result, the time they spend riding the bicycle will more than justify the cost.
