The Workhorse 二八大驴 (èr bā dà lú)

Card description:
If you were a merchant in China between 1970 to 2000 and you were looking for a product to sell, you cannot go wrong with selling or maintaining these 28-inch wheels bicycles. They probably transported more people to-and-fro in China than any other form of man-made transport in history.

Even today, you would still see elderly folk riding around town with one of these, with its signature C-shaped handlebars with a little bell on one side, and a bare metal rack to ferry their grandchildren or carry their groceries.
