Trek Precaliber 24 8-speed Suspension

Precaliber 24 8-Speed Suspension is a versatile kids' bike built for young adventurers who love riding off the pavement and into the dirt. It has a sturdy yet light aluminum frame with a performance suspension fork and an 8-speed drivetrain perfect for racing home from school, zipping through the woods, and riding trails and paths with family. For kids ages 8-12, between 51-59˝ tall.

• This bike can get your youngster hooked on a lifetime hobby that's healthy, environmentally friendly, and fun
• Intuitive twist shift makes it easy for kids to switch gears when their terrain changes
• You can replace the saddle's integrated handle with an integrated light mount to boost visibility on family adventures and solo excursions
• Like all Precaliber bikes, the frame is lower so it's easier for kids to stand over and hop on and off
• Investing in a kids' bike from an established bike brand is worth it—Trek kids' bikes are designed and assembled by people who know bikes

Integrated handle

Hidden handle under the saddle helps you guide your child while they learn to ride.

Suspension fork

Front suspension absorbs the bumps of the road, path, and trail, and looks cool while doing it.

A better way to produce aluminum

Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
