Trek’s Precaliber 24 is a true mountain bike perfect for even the most-active kids. It features a lightweight aluminum frame, bump-smoothing suspension fork, stout wheels with all-surface Bontrager tires and a hill-flattening 21-speed drivetrain. Simply put, it’s ready for anything from a ride to school to a summer of singletrack fun. The low stand-over height ensures safety and a proper fit for growing riders. Plus, the saddle is super comfortable and the short-reach brake levers mean solid stopping power for smaller hands.
