The Rocky Mountain Reaper 26 is the trail bike built to grow with your kid
What Our Gearhead® Experts Are Saying:
"The Reaper 26 is the kind of kids' bike that makes parents do a double-take at the spec sheet. A dropper post, tubeless-ready Maxxis Minions, and a clutched drivetrain on a kids' trail bike - Rocky Mountain clearly built this for young riders who are serious about the sport. I love recommending it to families who want a bike that won't hold their kid back."
Who It's For
The ambitious young rider ready for a real trail machine
The Reaper 26 is built for kids who are ready to push into more technical terrain and want a bike that keeps up. The RIDE-2 geometry system means the frame stays relevant as they grow, making this a smart long-term investment for families committed to the sport.
What It's For
Singletrack, bike park laps, and progressive trail features
With 130mm of travel front and rear, the Reaper 26 handles natural singletrack, jump lines, and chunky trail features with confidence. Wider Maxxis Minion tires and tubeless-ready rims give young riders the grip they need across varied conditions.
Why We Like It
Grown-up trail performance scaled down for younger riders
Rocky Mountain built the Reaper 26 with FORM Alloy construction, a size-specific suspension tune, and Smoothlink kinematics that punch well above their travel rating. The dropper post and clutched MicroShift drivetrain are touches that make a genuine difference on the trail.
Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
