Trek Roscoe 24


SKU: N/A Category:



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 51-59″ tall.

Its 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 youre looking to teach your little one the wisdom of the trail, theres no better teaching tool than Roscoe.

The tech you get
A durable Alpha Gold Aluminum frame with a sloping top tube for added clearance, 24″ wheels with mid-fat 2.8″ tires for added traction and stability, a 1×8 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 doesnt mean an automatic trip to the shop for a replacement part.

The final word
Give a kid a Roscoe and youll 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 thats made to build confidence, skills, and a healthy obsession with the worlds greatest activity.
