• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

I don't think your insurance will cover what that thing did to your car house neighborhood

So you've decided for your character's Cool Car to be a motorcycle. But aren't hogs overdone by Hells Angel lookalikes and feeling that the Japanese bikes are too generic? Then lucky for you there exists a type of motorbike called the Monowheel that is essentially a motorcycle IN A GIANT WHEEL.

This type of vehicle is typically used in futuristic or fantasy settings despite it having pedal versions in the late 19th century.

The issue of fast acceleration and sudden braking leaving the rider spinning inside the wheel itself is usually ignored or handwaved.

Examples of Monowheel Mayhem include:


  • In a 2007 television commercial produced for the drink brand Capri Sun, a boy and a girl are both riding in variants which appear to be manufactured vehicles made of metal and fiberglass (up to the point where they are levitated into the air by a CGI effect).

Anime & Manga

  • Jack Atlas in Yu-Gi-Oh! 5D's has one of these as his D-Wheel. A D-Wheel fit for a former king.
  • Ray Steam in Steamboy builds a pedal/steam powered one.
  • Jean from Nadia: The Secret of Blue Water uses one. It even appears in the opening, at least in the French dub.
  • Many mobile suits of the Zansacre Empire in Mobile Suit Victory Gundam use Einrads, giant versions that they stand in. They can also fly.
  • Some of these eventually show up in the Gantz manga. Although their users tend to die just as horribly as everyone else.
  • A chapter of Kochikame has a mad scientist creating cars of the future that uses a renewable energy (mostly unimpressed). Ryotsu is impressed of the monowheel and goes for a joyride. Until the wheel goes out of control when he stops at the red light and knocking him unconcious.
  • Amazing Three features three agents from outer space who travel in a tire-shaped vehicle called the Big Wheel, which can travel at enormous speeds on both land and water (and, with modifications, through the air).
  • In the OVA series Dirty Pair Flash Mission 3, a young female assassin called Monica drives a Red Futuristic Monowheel.
  • In the animated adaptation of Venus Wars, one-wheeled motorcycles are used both in bloodsport and combat.


Films — Live Action

  • In Star Wars Episode III, General Grievous tries to escape Obi-Wan by riding a Wheel Bike that also has some legs for those rough terrain.
    • Destroyer Droids in all three prequels fold up into monowheels to maneuver around. The Clone Wars animated movie took advantage of the lack of shields in this mode to render them into scrap.
    • A Transformers Crossover figure. They noticed that the Wheel Bike looked like Grievous enough to make a figure of Grievous that transforms into it.


  • There's a very cool one of these in Iain M. Banks' novel Against a Dark Background.
  • Robert Heinlein's The Cat Who Walks Through Walls. While traveling on the Moon, the vehicle the protagonists are in is attacked by a giant Monowheel. It had gunpods sticking out from each hub.
  • Stanislav Lem's novel Eden features motorized variants of the monowheel.
  • There's a living example in E. E. "Doc" Smith's Lensman series novel Galactic Patrol. The Wheelmen of Aldebaran I are literally wheel-shaped aliens, with their heads where the hub would be, and dozen of arms with capable looking hands. They move around by rolling like wheels.

Live Action TV

  • One episode of Scrapheap Challenge had the two teams constructing monowheels and then racing them around a test track.

Tabletop Games

  • The Skaven of Warhammer recently got one of these; a weird gunned-up, blade-covered wheel powered by hundreds of running rats.
  • Arduin Dungeon #1 Caliban had a magikal construct called a "Warwheel" that ranged from 10-24 feet high.
  • The fourth edition of Shadowrun features a monowheel called the Horizon-Doble Revolution.
  • Hollow Earth Expedition supplement Secrets of the Surface World. In the Weird Science chapter, the example of the creation process is a Wheelbike: a single large wheel running around the outside of a gyroscopically balanced cockpit and engine.

Video Games

  • In the most recent Dune RTS game, the Harkonnens have the Buzzsaw, which specializes in ruining Spice fields or slicing through infantry formations. No explanation on how the blades stay sharp after traveling over rocks, though.
  • One of the enemies in Super Smash Bros Brawl's Subspace Emissary is essentially this. A common Kirby enemy, as well.
  • This is one of the party's primary means of transportion in Wild Arms 5. In the penultimate battle, Dean turns it into a weapon. MONOWHEEL TO THE FACE, BITCH.
  • Mega Man 4 has the first variant of the "Roader" enemy. The roaders that appear in later games look less like a monowheel, though.
  • This is one of the Extreme Gears you can use in Sonic Riders: Zero Gravity.
  • You can fight some of this in Airforce Delta Strike.
  • In Kirby Super Star, the helper from the wheelie powerup is a monowheel.
  • In Wild Arms 5 the main character Dean obtains a monowheel for faster transportation around world map areas.

Western Animation

  • In Chaotic, the Mowercycle (as pictured above) is this plus some metal teeth that can either be used to climb vertical surfaces and even run across cavern ceilings or be used to vandalize your enemy's city by powersaw-ing through their stone statues.
    • A recent set release of the card game introduced the Bi-Mowercycle. As you can tell it has two wheels to allow more city wrecking fun. Although this may disqualify it for being a monowheel of doom.
  • An episode of Justice League had Nazis using the War Wheel from the Blackhawks example.
  • Similarly, the Big Wheel appears in Spider-Man: The Animated Series.
  • The South Park episode "The Entity" has Mr Garrison invent 'IT', a high speed, super efficient monowheel. Despite the control system requiring a joystick up the ass and in the mouth, it's still wildly popular as "it's still better than dealing with the airlines".
    • And one can only guess how popular it would have been if they'd figured out that you don't need to use the anal/oral joysticks to move - there are alternative controls on the IT too.
    • An early title for this episode was "The Ginger Device." It was making fun of the not-yet-released Segway, which at the time was a closely-guarded secret with lots and lots of wild public speculation.
  • Colonel Dirk Courage, The Hero from Spiral Zone, drove the Rimfire, a monowheel with a BFG on top.
  • Pre-dating Episode III by twenty years, the Droids cartoon features a monowheel.
  • In Wakfu, Nox's Mooks ride such monowheeled vehicles to battle, looking like giant clockwork cogwheels.
  • A futuristic version of the monowheel is shown in a few episodes of Teenage Mutant Ninja Turtles 2003.
  • In Hot Wheels Battle Force 5, The Red Sentient Kytren uses The Vyirex which is a gyroscope monowheel (hence the name).
