If you had one bike that could survive a theoretical zombie apocalypse, it’d be Diamondback's 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 durable and capable of carrying you and your gear over any kind of terrain (check out the rack mounts), this fat bike is just plain fun to ride. The extra wide tires on el Oso Uno provide outstanding traction, and you can mount tires up to 26x5" wide for extra float over soft surfaces. Aboard el Oso Uno, you can survive anything the trail throws your way, including the occasional zombie horde.
