I finally saw a fat bike in the snow the other day when I was cross-country skiing (99% of them seem to be hipsters on paved rail trails and roads
) Anyway, it looked like fun but not fun enough to spend thousands to buy something decent or to cut into my skiing time. I also wonder with the extra-wide BB if one would develop knee problems from riding one of these? Any serious road riders out there who also ride a fat bike to comment on that?
