Precaliber 24 8-Speed is a classic kids' bike with great style, performance, and durability. It has the simplicity of an 8-speed drivetrain and intuitive twist shift that makes it easy for kids to ride varied terrain.

A strong, lightweight aluminum frame that will stand up to whatever your youngster dishes out, with simple and reliable Shimano 8-speed shifting that makes it easy to climb hills. Plus, it has a kickstand, and a saddle with an integrated handle that can be swapped out for an integrated taillight mount.

Whether your kids are riding to school, racing around the neighborhood with friends, or tagging along on family rides, Precaliber 24 8-speed features the quality parts they need to ride with confidence and stay in control.

- Intuitive twist shift makes it easy for kids to switch gears when their terrain changes
