I have yet to break a spoke, though I've only put on ~250 miles this spring, maybe I lucked into getting pick of the litter wheels?? dunno
But I am happy that I've lost a little over 15lbs thus far, and not just water weight either! I can feel my pants fitting a bit looser and am almost able to fit into a few shirts I've had sitting around for a while.
Hopefully, by the end of this month I'll be in the sub 300lb group, things are looking up and it looks like I'll start commuting as early as next week, can finally afford to get a light and some cargo packs.
