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.

Why you'll love it

1. Intuitive twist shift makes it easy for kids to switch gears when their terrain changes
2. You can replace the saddle's integrated handle with an integrated light mount to boost visibility on family adventures and solo excursions
3. This bike is hand-me-down heaven: it's built to last, so younger siblings can inherit this bike and it'll still feel like new
4. Like all Precaliber bikes, the frame is lower so it's easier for kids to stand over and hop on and off
5. You shouldn't buy your kid's bike where you buy your cereal – Unlike big box brands, Trek kids' bikes are assembled by people who know bikes
