not a serious thing for me, but i think i'm going to try an aluminum dk duke as my fat bike. i mostly pick up cheapie fat bikes to cut up for other experiments, but since i can't weld aluminum (but got a good deal on this used)i'll leave it alone and it'll be my try at having a regular fat bike. i'm hoping being aluminum it'll be a little lighter than the normal cheap fat bike, but i'll need to swap around some wheels to get rear disc brakes too (comes with rear rim brakes, but has a caliper mount point).
