Account Deleted By User I've only ridden a fat tire bike once. My impression was that they have a place in snow, but otherwise they're slow and not very maneuverable. 29ers are much better suited for the single track trails in my area for 8 months out of the year.  But lately, there's been an epidemic of fats riding fatties, clogging up my trails like plaque in an artery. It seems like every tub with a skin tight full body spandex racing suit bought one just because they have the same nick names. It's a double whammy because the bikes are naturally slower, and the fats are slower. The only positive that I can see is that once it hits 80 degrees, it'll be too hot for them to go outside.
