Yeah ........same as Bill. I never had a problem (Except for the old days with canti brakes and the snow would build up on the straddle cable)........but still no problem....cause I dont ride in the snow.
I went to Florida in February. While in florida we went up to coa coa beach and rented Fat Bikes. We hit the beach and headed north. Lots of pedaling on the hard sand, but I didnt get the thrill many get. I would guess if I did Purchase a fat bike I would get a cheapo. Only because Riding on the beach would get salt all over it and for me in the snow wouldnt matter.
So I would suggeest if you must snow ride, get a cheapy.
