Chinese wheelbarrows with sails.
Another great article from one of my favorite blogs. Note that despite his admiration for the Chinese wheelbarrow design, they have the same back-twisting problem of our one-wheel wheelbarrows.
Note also that this might actually be a use for computer-controlled unicycles. He speculates that the roads were poor and narrow, allowing for only a single wheel. A computer-controlled one-wheel balancer would be able to negotiate the narrowest of trails. Of course you might object that any society still capable of building them would have a transport system, but what about niche uses, like Afghanistan or trekking Antarctica?
Carrying a passenger
The Chinese wheelbarrow – which was driven by human labour, beasts of burden and wind power – was of a different design than its European counterpart. By placing a large wheel in the middle of the vehicle instead of a smaller wheel in front, one could easily carry three to six times as much weight than if using a European wheelbarrow.
The one-wheeled vehicle appeared around the time the extensive Ancient Chinese road infrastructure began to disintegrate. Instead of holding on to carts, wagons and wide paved roads, the Chinese turned their focus to a much more easily maintainable network of narrow paths designed for wheelbarrows. The Europeans, faced with similar problems at the time, did not adapt and subsequently lost the option of smooth land transportation for almost one thousand years….
