" I try to sit down at the typewriter four times a day, even if it's only five minutes, and write three sentences. And if I feel like going on, or if something turns me on I'll just keep writing till I'm written out."
- Roger Zelazny

| 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.
Here's another illustration, and a quote (they don't write them like this anymore):
(('The Roads Must Roll' by Robert Heinlein)“Hie! Hie! Hee! The rotor men are we — Check off your sectors loud and strong! ONE! TWO! THREE! Anywhere you go You are bound to know That your roadways go rolling along!”
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.
Compare to the gyrocar from Two Boys in a Gyrocar the story of a New York to Paris motor race (1911) by Kenneth Brown, the Gyro-Hat from An Experiment in Gyro-Hats (1926) by Ellis Parker Butler, the Two-Wheeled Ground Car from First Lensman (1950) by E.E. 'Doc' Smith, the Gyro Two-Wheeled Truck from The Sign of the Tiger (1958) by Alan Nourse (w/Meyer), the Gyrocar (Gyro) from The Ring (1969) by Piers Anthony (w/R. Margroff) and the smart bike from Distraction (1998) by Bruce Sterling.
