Trek Precaliber 12 Boys Bike size_148 a comfy cuffPrecaliber 12 Boy's is the perfect first bike for little riders who are ahead of the curve and ready for two wheels at a younger age than most. It has a handle built into the saddle so you can guide them as they ride, and tool less training wheels that are super easy to install and remove. It's a great fit for kids ages 3 4, between 36 40 tall.
