I have an ICAN fat bike frame and wheel set. I have two seasons on them and so far so good.

The wheels are still true, in spite of being ridden by a 250+ pound rider. The frame is just fine too.

Most of my miles are on packed single track snow trails. So lots of hard use and no issues. The only other fat bike I have ridden was a Specialized aluminum Fatboy and the ICAN is the better bike, and it is 5 pounds lighter at about the same price that the now discontinued Fatboy sold for when I bought my ICAN.
