Fat bikes are a blast to ride but when the weather rolls in those big tires throw up a lot of snow, mud, dirt, water... you name it. Fenders are a must have on a fat bike and one of our favorites is the Axiom Rearrunner Fat Bike Fender. They're easy to install and offer plenty of coverage.
A minimalist rear fender that mounts to the seatpost or seat tube.
Broke on the first use. I had it fastened loosely to the seat post, yet when I inadvertently hit the fender with my foot while mounting the bike, the fender support snapped. Upon review, the design for the support is extremely weak and needs revision. Thankfully, I bought it at Fyxation; they warranted the part and set me up with another product. Fyxation is everything a bike shop should be.
Easy assembly. Robust design. Very cool aesthetics.
