"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. |

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.
