Kids' Fat Bikes

We've got some incredibly fun and rugged fat tire trail bikes for kids that are irresistible for both looks and capabilities. Meet the Trek Roscoe and Salsa Timberjack.

Trek Roscoe

Roscoe 24 is a mid-fat kids' mountain bike designed to build confidence on the trail. It takes cues from the adult Roscoe, but this ride was built from the ground up for kids. 2.8˝ mid-fat tires, a 1x drivetrain, and a wide-range cassette make Roscoe the ideal bike for little rippers who want to build skills and have a ridiculous amount of fun keeping up with Mom, Dad, or an older sibling. Fit for riders 50-63˝tall.

It's right for you if...

Your little shredder is ready to hop off the neighborhood streets and onto the trail, and you want to get them started the right way with a real-deal mountain bike that builds skills and confidence from the outset. If you're looking to teach your little one the wisdom of the trail, there's no better teaching tool than Roscoe.

The tech you get

A durable Alpha Aluminum frame with a sloping top tube for added clearance, 24˝ wheels with mid-fat 2.8˝ tires for added traction and stability, a 1x8 Shimano drivetrain with a wide-range cassette for hills and technical sections, mechanical disc brakes, and loads of thoughtful details borrowed from adult MTB tech, like a closed front dropout and a tucked-in rear brake caliper so when kids drop their Roscoe it doesn't mean an automatic trip to the shop for a replacement part.

The final word

Give a kid a Roscoe and you'll make a mountain biker for life. Mid-fat tires and a wealth of kid-specific design details make this bike the perfect introduction to the trail. If your little one is ready to tag along when you hit the singletrack, this is the kid-friendly set-up that's made to build confidence, skills, and a healthy obsession with the world's greatest activity.
