The 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. Plus, the strong yet lightweight aluminium frame stands up to even the roughest riders. For kids aged 8-12, between 129.5 - 149.8 cm (51-59?) tall. Your kid loves to explore, and you want them to have a quality ride for all their road, path or trail adventures. They're ready to upgrade from a singlespeed for a little extra help on hills and longer rides, but they don't need a ton of gears just yet.
