I ride a Bacchetta Giro 26, with rack and bags on it, as a daily commuter. Every day I take it up and down the stairs from my sun room to the driveway (about five steps). The bike has a large 'brain box' bag on the back of the seat, with a grab handle right in the center of the backrest on the bike. I grab the handlebars at the center (where the riser and handlebar come together) and the grab handle and go up the stairs. Then I set it down for a moment while I reach forward and open the door, and in we go. Going out, especially fully loaded, I lift the front tire, and let the rear go down the steps, thump-thump-thump-thump-thump! Then go back and close the door. If I had to carry it up a full flight of stairs (I have in a hotel) it's the same carry as I just described, and the same thump-thump-thump going down.
