You will find bicycles being used as roaming restaurants, complete with stools, which can be set up for the customers when parked. These will include a stove and all of the supplies needed to set up a temporary restaurant. Sometimes it is amazing what people can fit on a bike. The other day, I saw someone tying a 20-inch television to the rear rack of his bicycle. Just today, I saw a man carrying a 20-foot long load of steel bars on his tricycle dump truck.
Bicycles are also very inexpensive in China.
Of course, I am really enjoying riding my bike in China. I feel much more fit after just a month.
