The Merida Matts J16 Boys Bike is designed for 3-6 year olds, offering a lightweight alloy frame that is easier to handle than typical steel frames. This bike features a lower standover height and 16" wheels, providing comfort and control. As children improve their riding skills, the training wheels can be removed, transitioning the bike from four wheels to two. It's an excellent option for a first bike or as an upgrade from a toddler bike.
