I think that some of the answers here are tuned more toward the type of bike to ride. Even with frame designs to accommodate the changes the easiest way to get the bike easy to ride at a high weight is using a lower rolling resistance wheel/tire combination. A heavy weight frame can be off set by a lighter wheel and tire combination. I spend time watching the videos and infomercials from Silca USA and they are the bomb! However they are in the camp of creating lower resistance to movement via the wheels and tires. Same concept works for even the heaviest of bike frames and wheel sets. Lower rolling resistance is what you are after. Smiles, MH
