Overview
About this bike
Built for future slayers. The Reaper packs the same aggressive trail performance found in our full-suspension bikes like the Altitude and Instinct, but in a smaller package for young rippers. Don't fear the Reaper. The Reaper can tear up singletrack, smash technical descents, and slay bike park laps all day long. And, because we know that kids grow (and have younger siblings), the Reaper is easily convertible from 24" wheels to 26" wheels and vice versa. We also have the Reaper 27.5 option to keep your kids shredding longer!
