14 New Fat Bikes Released this Winter

Diamondback El Oso Series (5 bikes)

Not content to launch just one or two fat bikes, Diamondback has gone from zero to hero with a full 5-model fat bike lineup, dubbed “El Oso Series.”

The namesake for the entire line, El Oso (“The Bear”) is the most expensive of Diamondback’s new fat bikes at $2,300 MSRP. However, it backs that price up with a lightweight aluminum frame, 100mm RockShox Bluto fork, Shimano 2×10 drivetrain with SLX Shadow Plus rear derailleur, and Kenda Juggernaut 4.5″ tires.

El Oso Grande keeps the same frame (and tires in the 5″ range) as El Oso but shaves the price down to $1,700 by opting for a rigid aluminum fork and cheaper components, like a SRAM X5 2×10 drivetrain.

If you want a bike that gets comments at the trailhead, then this rig is for you. A gaudy camo paint job combined with green Chaoyang Cruiser 4″ tires and camo brown rims make for a picture-worthy fat bike that can’t be ignored. However, the changes from the previous two models are more than skin-deep. In addition to the narrower tire standard, El Oso de Acero Camo also features a rigid steel frame for a more classic design. You may have already guessed this if you’re fluent in Spanish–“acero” means “steel.” The drivetrain is also an older-model 3×9 Shimano Alivio, and the cheap components keep the price down at $1,100.

This rig keeps the same steel frame and fork and a very similar parts spec to the model above, but opts for a more subdued paint job. The price is also a bit more affordable at $950 MSRP.

Diamondback’s take on a budget fat bike, this $600 model is probably named “Gordo” since it’s friggin’ heavy! (“Gordo” translates as “fat.”) The same steel frame from the two models above is loaded with big 4.4″ tires and a cheap 1×7 drivetrain with a grip shifter.
