27.5” – Available on rare occasions among hybrid or mountain fat bikes.
*29er fat bikes are not around, although a 26″ and 27.5″ with the fat tire make up the size of an original 29″ MTB wheel!

RIGID vs. SUSPENSION on a Fat Bike

There’s no need for suspension on a fat bike as the large-volume tires offer plenty of comfort for the ride. Besides, suspension consumes a fair amount of energy, and the good part about having a rigid frame is that the 20×4.0 fat tire keeps a better momentum compared to suspension bikes as well. Some ebike fat tire come equipped with front suspension, but you shouldn’t worry about the momentum since the bike is powered by an electric motor.                                               


Are fat bikes slow and hard to ride?

Riding a fat bike might seems like a lot of work due to the extra rolling resistance of a wider tire, but the majority of non-electric fat bikes are quite lightweight and nimble on the right surfaces. They perform best on soft surfaces like snow and sand (the reason they were originally built). Now add an electric motor and it takes away most of the effort needed to pedal the bike through soft surfaces.
