Is there a component "group" that is uber-clyde friendly?
I have good news and bad news. The bad news is that you are officially out of the uber-clyde group (300+ lbs) and are now in the Clyde group. The good news is that virtually any bike out there is going to work for you. Go out and do some test riding and see what feels comfortable to you. Popular options here include "relaxed geometry" road bikes, rando & touring bikes, mountain bikes with lockable forks & hybrid/cruisers. You'll want a qualified person to really go over the wheels carefully... that is the primary failure point for most clydes.
