The Trek Precaliber 12 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-free training wheels that are super easy to install and remove. It's a great fit for kids aged 3-4, between 36–40˝ (91–102 cm) tall.
Sunset Cycles offers the 2025 Trek Precaliber 12 kids' bike in Flamingo Pink finish with free delivery.
