My last bicycle (a Swobo Sanchez) got stolen last month, need a replacement.

I just moved into the 11th floor of a building whose elevator fails all the goddamned time — I'm going to be carrying this up a LOT of stairs. So the big factor is weight.*I don’t particularly care about comfort. But looks count a little…*one salesman tried to push a Specialized Langster on me, there’s no way I would spend money on something so gawdforesaken ugly.

(and sorry, but I don’t have the time to research and assemble from parts)

Any suggestions are greatly appreciated.
