"Cyberpunk worked when the Internet was in its hand-wound crystal radio phase, when you had to be a sort of hobbyist to do e-mail, and it all had a very steep learning curve. Those days are over."
- William Gibson

Tumblebug  
  A monocycle; a motorcycle that balances on a single wheel.  

In this excerpt, the unthinkable has happened; the rolling roads have been sabotaged. Chief Engineer Gaines assembles his maintenance cadets and sets out to inspect and repair the damage.

Gaines and Harvey mounted tumblebugs, and kept abreast of the Cadet Captain, some twenty-five yards behind the leading wave. It had been a long time since the Chief Engineer had ridden one of these silly-looking little vehicles, and he felt awkward. A tumblebug does not give a man dignity, since it is about the size and shape of a kitchen stool, gyro-stabilized on a single wheel. But it is perfectly adapted to patrolling the maze of machinery 'down inside', since it can go through an opening the width of a man's shoulders, is easily controlled and will stand patiently upright, waiting, should its rider dismount.
From The Roads Must Roll, by Robert Heinlein.
Published by Astounding Science Fiction in 1940

Here's what they thought it would look like in 1940:


(Heinlein tumblebug from Astounding SF June 1940)

The oddest thing about a tumblebug is that it relies on "gyro-stabilization" the way we normally rely on two wheels. The Segway, a two-wheeled conveyance, similarly relies on gyro-stabilization.

Be sure to see how a modern company has created a monocycle concept vehicle similar to the tumblebug: read EMBRIO Embodies the Tumblebug. Closer yet, read about the Eunicycle Gyro-Stabilized Single Wheel Scooter.
