Diamondback El Oso Uno Steel Fat Bike

We’re not saying the zombie apocalypse is nigh. The world seems fairly shy of zombies, after all. What we are saying is that if you had one bike that could survive a theoretical plague of the undead, it’d be el Oso Uno. Oddly enough, you’d be riding through said apocalypse with a great big smile on your face, because in addition to being bulletproof and capable of carrying you and your gear over any kind of terrain (check out the rack mounts), this bike is just plain fun to ride.

Diamondback has decked out the sleek and forgiving steel frame with 4” tires that allow el Oso Uno to float over obstacles big, small, and absolutely monstrous. Powerful mechanical disc brakes keep you in control at all times and a Shimano 2×9 drivetrain ensures you never run out of gears for the steepest of climbs.

Aboard el Oso Uno, you can survive anything the trail throws your way — be it rock, sand, snow or the occasional zombie horde.

  • El Oso Uno’s hand-built steel frame is nigh bulletproof. Its 170mm rear hub spacing will fit tires as large as 26x5"
  • Shimano Acera 2x9 drivetrain provides accurate shifts and low gearing
  • Diamondback’s 73mm wide rims and 32-hole disc hubs take the hits
  • Diamondback’s El Oso Custom rigid steel fork is disc compatible
  • Tektro Novela mechanical disc brakes bring you to a tidy stop
