It's right for you if...

You love exploring nature on your bike and want your little adventurer to come along. You're looking for a high-quality kids' bike with adjustability, so your little shredder won't outgrow their new ride by the end of their first season.

The tech you get

A lightweight aluminium frame, a simple 6-speed drivetrain that's easy for kids to handle and a front suspension fork to smooth out the bumps on the road and trail. Plus, it has parts designed specifically for kids, like a saddle, grips, pedals and a dialed adjustable crank that lets this bike keep up with growth spurts.

The final word

When you're young, just being outside is an adventure. Precaliber's mountain bike styling makes it the perfect vessel for young explorers. They may pretend to be scaling dangerous mountains or escaping terrible beasts, but with a high-quality build and components, you'll always have peace of mind.

favorite_borderWhy we love it

  1. We all know that kids grow up fast, and our adjustable Dialed Fit system allows this bike to grow with them
  2. 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
  3. 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
  4. Trek quality = safety and fun
