Precaliber 12 Boy's

Model 21883

Precaliber 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.

Your kid may be young and small, but they're ready to ride! You want to make their first real bike experience a great one with a bike that's comfortable, durable, and fun. You also understand the importance of adjustability, and want to be able to pop off the training wheels without tools and adjust the fit easily when the time is right.

This toddler-friendly bike has a handle built right into the saddle so you can help guide your child while they ride, plus tool-less training wheels that can be installed and removed at the turn of a dial. The lightweight aluminum frame is easy for your little one to maneuver, and it's equipped with parts that are easy to adjust as they grow.
