Our El Oso fat bike really is as much fun to ride as it looks. Throw your leg over it and you may notice most of the bike is pretty standard stuff, at least for Diamondback: a strong and lightweight aluminum frame made with hydroformed tubing, a 120mm travel Rockshox fork, a smooth-shifting Shimano 2×10 drivetrain. If you can keep yourself from looking down as you pedal away, you’ll notice it doesn’t feel too much different from a normal bike, either. Designed to excel in sand or snow, the high volume / low pressure tires gain purchase on surfaces that have long been unrideable. But you don’t have to ride in sand or snow to experience the amazing traction of these tires—a spin on your favorite local trail will have you grinning ear to ear. El Oso does indeed excel on dunes and snow, but it’s not limited to them. It’s a capable trail bike as well! Wherever you choose to ride it, one thing’s for sure: El Oso is a blast.
