On conventional tandems, the front rider steers as well as pedals the bicycle and is known as the captain, pilot, or steersman; the rear rider only pedals and is known as the stoker, navigator, or rear admiral.
The term Tandem refers to the arrangement of the riders one behind the other rather than the number of riders. Bicycles for three, four, or five riders are referred to as "triples" or "triplets", "quads" or "quadruplets", and "quints" or "quintuplets" respectively. One such familiar to UK TV viewers was the "trandem" ridden by The Goodies.

3. Your car has broken down! Don't worry, there is a spare seat on my Tandem Bike. Just sit down, put your feet on the pedals, and don't lean to the side while peddling.
