A ~50 pound Mongoose singlespeed with 4.25″ tires and a coaster brake.
Looks like some hefty rims, all steel frame, and the Spider tires (27TPI, heavyheavyheavy) that come on the Sun Spider fatbike.
The start of a new trend? Perhaps. I am hopeful that fatbike exposure will mean more parts availability. I am fearful of what it will actually mean.
I guess fatbikes are now officially mainstream.
