So, I finally bought a fat bike. I picked up a Framed MN 1.0 with the extra wheelset. So far, I’ve ridden it around the park and the yard, and had a blast! Since I’m expecting to do winter commuting on this bike, I also picked-up a Planet Bike Versa-rack It does fit, at full leg extension, but the block that holds the front stays barely clears the top of the tire - as in less than 1cm … I also have some SKS Grand DAD/MOM fenders on order. I am SURE that the rear fender will have issues. I may have to choose between fenders and rack (unless I want to do something custom for a fender, based around the rack). Given that I ride the bike so that it carries things (as opposed to me carrying them), I think the rack will stay - assuming that the close point on the tire doesn’t accummulate snow.
I got the MN1 because I actually prefer a 1x drivetrain. The only other parts spec that is under what I’d prefer are the brakes - they are BB5s. So far, I think they will be fine. But, being the parts hoarder that I am, I actually have a pair of BB7 calipers sitting in the parts drawer, so I can easily mount them up and have a cheap (for me) upgrade. I think the tires are also kind of a low-budget thing, but I think I’m going to go the winter and see how it is before I make any changes.
