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.

- When you're learning to ride, simplicity is best: a 1x8 drivetrain lets kids focus on keeping the rubber side down

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
