As a mountain biker, you actively seek out challenges and obstacles. The Diamondback Atroz 1 - 27.5" Mountain Bike is the perfect tool for the job—whether you’re a trail-seasoned vet or are heading into the woods for the first time.

People say you have to spend a hell of a lot of cash to buy a full-suspension bike. Or at least a full-suspension bike that truly performs. They’re usually right. Usually. But not this time around. The Atroz proves them wrong with four inches of a reliable coil-sprung rear suspension that nicely smooths out the trail. Since you’ll need to climb to the top of the mountain, we’ve also given the Atroz an 18-speed Shimano drivetrain, and when it’s time to head back down, you’ll find the Suntour XCM suspension fork and Tektro Aries mechanical disc brakes keep you firmly in control of the descents.
