Just last week, I saw a guy riding a bicycle (funny how popular they've gotten recently), with a sturdy (non-collapsible) hand truck fastened to the seat post. He had quite a bit of "stuff" loaded on it, covered with a tarp. I would estimate that the angle was about 30 degrees above level. He was moving at a decent clip down the highway (not freeway).

I thought it was a great idea for the "use what you've got" transport scenario.
