Trek Roscoe 20 Mountain Bike

Roscoe 20 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 45-52˝tall.
