Who wouldn't love the rugged looks and monster tires on this fat bike? The Diamondback El Oso Nino is made for kids who want to monster truck over everything in their path.

  • Features

    • The frame and fork of this "little bear" are made from high-tensile steel that's tough enough for life around the neighborhood and in the woods
    • 7-speed Shimano drivetrain is controlled with grip shifters to charge up hills; powerful disc brakes allow controlled descents and stopping
    • 4-in.-wide tires sit atop 20 in. wheels; low tire pressure allows the bike to grab every bit of traction available, with extra float for soft surfaces and sand

    Imported.
