Ready to get rowdy
With 150mm front travel, trail-smashing 29-inch wheels, and dialed-for-dirt frame features, Roscoe is ready to get rowdy on your favorite rides.
Rock Solid
The bolt on downtube guard will stay put even after ripping though a chucky trail, keeping your bike quiet and protected.
Integrated storage
The frame bag is made from a recycled ripstop polyester with an eco friendly DWR coating on the outside that is water resistant, with plenty of room to stash everything from snacks to safety supplies.

Progressive trail geometry
A long reach, slack head angle, steep seat angle, and short chain stays combine for a ride that's confidence inspiring, yet still nimble and fun.
A better way to produce aluminum
Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
