Not necessarily. People are very ingenious when having to move lots o' stuff over long distances. If you had to move a lot of stuff a long way, and all you had was a moped or a bicycle, I'll bet you'd find a way to get it done. I saw a guy in Korea deliver a refrigerator, about the same size as the one on the bicycle, up an icy hill, with the fridge strapped to his back and a support strap around his forehead, on a smokin' moped. He got to the top of the hill, dismounted, and took the thing up three flights of stairs! Once, I saw five people on a Vespa in Italy too. I believe all of those photos are possible.
