The Blizzard packs the best in Rocky Mountain tech thinking to deliver a fatbike that’s as much fun as a trail bike.

That’s why the latest-gen Blizzard uses our smoothwall carbon frame design to shave grams for a lighter, livelier ride. Massive tire clearance and trail ready geometry keeps the ride feeling natural and fun, while a huge wack of contact points allow for plenty of waterbottles, bike bags, racks, you name it—all without adding weight or sacrificing strength.
