Tandem Bicycling

The tandem bicycle or twin is a form of bicycle (occasionally, a tricycle) designed to be ridden by more than one person. The term tandem refers to the seating arrangement (fore to aft, not side-by-side), not the number of riders. A bike with two riders side-by-side is called a sociable.
