2025 Marin Rift Zone JR 24 Dual Suspension Mountain Bike

REAL SINGLETRACK RIDING • KEEPING UP WITH THE PARENTS • FUN!

Because young rippers need that Rifty Love too! The Marin Rift Zone Jr is our take on the ultimate do-it-all trail bike for emerging shredders, offering genuine big-bike performance in a kid-friendly package. With 24″ wheels, 130mm of plush rear travel, a lightweight aluminum frame, and our renowned MultiTrac suspension platform, it’s fully equipped to bring big smiles on the trails—just like our grown-up Rifty.

Best of all, the Rift Zone Jr can grow with your child. The same frame, fork, and shock support both 24″ and 26″ wheelsets, so when your tween is ready to level up, you can simply swap the wheels (and crank arms) to keep them rolling in style.
