Citation? Flywheels can be very efficient especially with modern engineering. And it could be oriented so that the gyroscopic effects were stabilizing or destabilizing as desired, plus I think in any case riders would adapt quickly - I ride a "twitchy" bike with no front fork sometimes, and my old professor built a bike with a counter-rotating flywheel to disprove the myth that cyclists rely on gyroscopic effects to stabilize them.

What kind of citation are you looking for? This is just common engineering knowledge. The airtight safety housing alone would be way too heavy for bike racing. You can't have a flywheel spinning at zillion rpm sitting out in the open because it could kill someone in a crash. Plus the flywheel would need to be in a near vacuum to avoid air drag.

That's really interesting about the gyroscopic effects myth, as it is one I strongly believe! Is there some documentation of the bike or some analysis of this I can read?

It's not a myth that gyroscopic effects contribute to stabilization, but rather that it explains the stabilization fully. It's usually phrased as "scientists still don't understand how bikes work [in terms of their stability]", which is pretty amazing if you think about it.

Actually, since about 5 years ago bicycle stability is pretty well understood: http://bicycle.tudelft.nl/stablebicycle/

Prof Ruina? I loved his class.

No, Dr Hunt (see link in cousin). I actually only had him as a tutor but didn't want to complicate things.

Ah. I see that now. I had Ruina for Dynamics, and talked a bunch with Jim Papadopoulos. Fun Times.
