My friend recently picked up a specialized something or another w/ disk brakes n stuff. Anyways...I am a big guy and I've gained weight since I used to ride bike back when I was younger. I weigh about 400lbs now...is there even a bike I can safely ride? If so could you link me or suggest some...I rode a huffy or something of that nature...like a mountain bike frame and didn't have a problem with the seat or anything like that, so that's not my biggest concern. What I worry about is being able to stop and not break the frame or any components without excessive force. Any help would be appreciated. Biking is the one thing I used to like to do and I want to start losing weight so I figure I might look into something I used to like.....here is his new bike BTW....
