Fat bikes and pannier racks I'm trying to research fat bikes for rack attachment holes and have not seen any so far. I'm a long term commuter and must have a way of attaching my panniers to my bike. Backpacks are out because I'm a pack rat, plus I do my shopping with my bicycle and that won't work. I believe I saw one commuter with a rack that connected to his bike by attaching just above the wheel openings, but couldn't find a name on it to do some research. Can anyone offer some help? Thanks.
Many of the expedition/endurance race fat bikes will come with rack mounts.  If you plan on "packratting" and carrying groceries, you should avoid the seatpost only options.  They generally have low weight restrictions and can also have issues with the bags flopping into your wheels (they are often missing the side panels regular pannier racks have). 

If you look around a bit more, it should be fairly easy to find fat bike companies making rigs that are rack ready.  At most of the winter endurance races, racks and sometimes panniers are common.  The Surly Pugsley (the original production fatbike) still comes with rack mounts (rear AND front).
