They are not necessarily slower on climbs, but are perceived as such, in part due to the need for a high level of coordination between the riders, especially if the physical abilities of the two riders are very different, requiring a compromise on cadence. On flat terrain and downhill, most of the power produced by cyclists is used to overcome wind resistance, so tandems can reach higher speeds than the same riders on single bicycles. High-performance tandems may weigh less than twice as much as a single bike, so the power-to-weight ratio may be slightly better than that of a single bike and rider. It has about the same wind resistance as a conventional bicycle. Modern technology has improved component and frame designs, and many tandems are as well-built as modern high-end road and off-road bikes.Ĭompared to a conventional bicycle, a tandem has double the pedalling power, without necessarily doubling the speed, and with only slightly more frictional loss in the drivetrain. In the UK The Tandem Club was founded in 1971, new tandems came on to the market from the French companies Lejeune and Gitane, and in the USA Bill McCready founded Santana Cycles in 1976. Tandem popularity began to decline after World War II until a revival started in the late 1960s. They were also used in the Second Anglo-Boer War.
In approximately 1898, Mikael Pedersen developed a two-rider tandem version of his Pedersen bicycle that weighed 24 pounds, and a four-rider, or "quad", that weighed 64 pounds.
Patents related to tandem bicycles date from the mid 1880s. On most tandems the two sets of cranks are mechanically linked by a timing chain and turn at the same rate. 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. I'm half crazy / all for the love of you", ending with the words, "a bicycle built for two". This is in reference to " Daisy Bell (Bicycle Built for Two)" which is a popular song, written in 1892 by British songwriter Harry Dacre, with the well-known chorus, "Daisy, Daisy / Give me your answer, do. Tandem bicycles are sometimes called "Daisy Bells". A bike with two riders side by side is called a sociable. The term tandem refers to the seating arrangement (fore to aft, not side by side), not the number of riders.
