タンデム自転車
A tandem or twin bicycle is a form of [[bicycle]] (or [[tricycle]]) designed to be ridden and pedaled by more than one person. The term tandem refers to the seating arrangement from fore to aft, as opposed to side-by-side, and does not refer to the number of riders.  

Bicycles where the multiple riders are side-by-side are referred to as a sociable or buddy bike.
