A tandem bicycle is that type of two-seat bikes with two sets of pedals that aging liberal couples and teenagers in {{Public Service Announcement}}s ride everywhere. It works on the principle "2>1", according to which, it's easier to ride if there are two people doing the pedalling.

But, not all is good, because, as always, evil rears its ugly head in the form of a Tandem Parasite. This is the one in the back seat, whose parasitism is not visible to the hard-working, all-American front-seater. The rear-seater doesn't pedal at all, but rather crosses his leg and smiles as the poor soul in front of him does twice the work he should be doing - the idea here is that the rear-seater is mockingly taking advantage of the rider.

It should be noted that, sometimes, the parasite has some reason not to pedal, like being distracted, or having been hurt, if you buy those cheap excuses.

A DeadHorseTrope, or even a DeadUnicornTrope.


* An Australian ad for [=KitKat=] has a woman taking a break and eating a [=KitKat=] on the back of a tandem bike while her boyfriend continues to pedal.

* Team Rocket on ''Anime/{{Pokemon}}'' uses a lot of pedal-powered vehicles. About half the times they use one, Jessie sits back and lets James and Meowth do all the work, which occasionally leads to disaster.

* [[SuperDickery Superman, Batman and Robin]] [[http://superdickery.com/index.php?option=com_content&view=article&id=93:superman-a-batman-vs-robin&catid=28:superdickery&Itemid=54 in a World's Finest comic]]. [[ButtMonkey Robin was pedalling.]]
* [[ArchieComics Jughead and Archie]] did it. Archie was pedalling.

* Variation in the Creator/LaurelAndHardy short ''Film/TheMusicBox'' - as Ollie huffs and puffs pushing a piano crate, Stanley stands on the edge of the crate in front, hurriedly stepping off as Ollie stops and looks at him suspiciously.

* Two men on a tandem on going up a hill. Once they reach the top, the first guy wheezes out "Man, that hill was a lot steeper than it looked from down there!". The second responds "Yeah, no kidding. Imagine what would have happened if I hadn't been braking the whole time!"

* Robert Fulghum wrote a piece on this. A New Age couple riding a tandem bicycle. The guy in front thinks he's in control 'cause he decides where they're going. The gal in back knows she's in control 'cause she can stop pedalling and look around every so often. A nice essay on gender roles.
* Happens, of course, in Jerome K. Jerome's book ''Three Men on the Bummel'' (aka ''Three Men on Wheels''), the sequel to ''Literature/ThreeMenInABoat''.

* ''Series/TheGoodies'' Trandem is a three-man variation. The original version was an ordinary (sic) tandem with an extra seat at the back. Tim and Graeme pedalled, Bill being shortest was at the back in the non-pedalling seat. Later on the BBC prop department actually built a version with three sets of pedals.
* Variation with the Chucklemobile from ''Series/{{Chucklevision}}'', where the two brothers supposedly pedal side by side but Paul never bothers, even though Barry can see him not doing it. ([[IronButtMonkey Presumably he's just used to it at this point.]]) On some versions of the Chucklemobile prop it doesn't look like there even ''are'' pedals on Paul's side!

* This happens quite easily in ''WiiSportsResort'''s Cycling game if one of the riders doesn't know what they're doing or refuses to keep rhythm.

[[folder:Western Animation]]
* Burns and Smithers on ''WesternAnimation/TheSimpsons''. It gets worse when Smithers gets stung by a bee and begs Burns to get him to a hospital. How does Monty do it? By ordering Smithers to do it, of course.
* Brian and Lois on ''WesternAnimation/FamilyGuy''
* Kif and Amy in the ''WesternAnimation/{{Futurama}}'' episode "Three Hundred Big Boys". The twist is that it's a flying bicycle, and the pedals power the wings. In this case, Amy is just easily distracted (waving to some friends on the ground below) and wasn't trying to be rude.
** Bender and his two clones in "Benderama", only ''all three'' are leaning back. The bike promptly falls over.
* Mr Herriman does it to Bloo in the ''WesternAnimation/FostersHomeForImaginaryFriends'' episode "Let Your Hare Down" when Bloo is attempting to teach him how to have fun and Herriman isn't having a bar of it.
* In the Creator/TexAvery version of "WesternAnimation/GoldilocksAndTheThreeBears", Papa and Mama bear are the parasites, leaving poor Baby bear to do all the pedaling.
* In the ''WesternAnimation/LooneyTunes'' short "WesternAnimation/TheDoverBoys", Tom Dover is riding a tandem bike all by himself, with Dora Standpipe leaning on the front, which is left up in the air due to Tom being TheBigGuy.
* In ''WesternAnimation/LittlestPetShop2012'', Roger escorts the Biskit Twins on a tandem bicycle ride through a park in an attempt to get through to be nicer, and of course, [[http://static.tvtropes.org/pmwiki/pub/images/lps_tandem_bike_350x220_4638.jpg they made no attempt to cycle along with him]]. [[spoiler:Surprisingly, it works, to where they eventually pull a rickshaw for Roger in gratitude]].
