>>1781617I was up to that weight also, and a pretty low end aluminum mountain bike handled my weight fine. You'll probably kill saddles before the bike, since you won't be able to keep your weight off it by pedaling hard.
Like everyone is gonna tell you, all the exercise in the world won't do a fucking thing to your fat ass if you're not fixing the diet that put you there. As long as your diet is right, get any bike you want, because the weight will come off before you break the bike anyway.
But it's all absolutely fucking worth it.
