Product Information

Trek Precaliber 24 8-Speed Kids Bike

Trek has designed the Precaliber 24 8-speed bike as a great step up for your little one who's not so little anymore. Ideal for kids aged around the 8-12years old bracket, this bike allows them to move onwards and upwards from a single-speed to an 8-speed drivetrain. The benefit? They'll find it much easier to ride on slightly rougher terrain, helping them to get up hills and keep going for longer on family rides with more gear choice. Trek has built the Precaliber with an aluminium frame that is tough and reliable whilst also being lightweight for more control and better handling. Trek has designed this bike to fit your kids' needs, with their expert knowledge, they know what matters when it comes to keeping your young one both safe and comfortable; with an integrated handle into the saddle that can be swapped for a backlight mount keeping them visible to other road or trail users. Also coming with a built-in kickstand, they can easily stop and take little breaks when out on family rides or to pull up for a lunchtime snack. Trek has designed the Precaliber with a lower frame, making it more comfortable for your child to stand over their bike and jump on and off with ease. Finally, to help keep things simple, Trek added a twist-shift gear changing feature to make riding up and down hills efficient and enjoyable. 


Full Specification



The next step up

The Precaliber is great if 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 single-speed for a little extra help on hills and longer rides, but they don't need a ton of gears just yet. Whether your kids are riding to school, racing around the neighbourhood 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.


The safety technology & quality 

A strong, lightweight aluminium 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 rear light mount.


The extra details

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. Like all Precaliber bikes, the frame is lower so it's easier for kids to stand over and hop on and off. Intuitive twist-shift makes it easy for kids to switch gears when their terrain changes. 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.
