It will stay up by itself as long as it has traction and power (or
momentum).

So, according to your statement above, if I stand off to the side, give it a
good hard shove, and let go of it, the bicycle won't fall over until it
comes to a stop.

You lost the argument a long time ago so now all you have left is to display
your moronity.

Try this one: While riding a bicycle on a flat, level surface which way do
you move the right handle bar to initiate a left turn?

Correct, as long as the wheels don't slip.

The handlebars must be turned slightly to the right.

Why?

N2310D writes:

Why?

To force the bicycle's momentum to carry it to the left. The wheel
will then turn on its own to the left to restore the equilibrium, and
so will the bicycle.

Wrong. Guess again -- or use one of those fabulous references you claim
to have.

"Power" is unrelated to the gyroscopic stability in the equation. Bicycles
travel a large propoortion of the time without application of power to either
wheel. That you would list power to the rear wheel as one of a set of two
exclusive conditions required for the bicycle to remain upright proves that you
haven't really looked at the question very closely, and neither have any
sources you may be quoting.

Yes, through momentum. But this momentum is eroded by irreversible
effects such as friction with the ground and air. Eventually none is
left, and the bicycle stops.

As long as there is power to the wheel, it will compensate for any
losses, and the bicycle will continue to move. Similarly, as long as
the bicycle has momentum, it will continue to move. In both cases, as
long as the wheels retain their traction with the ground, the bicycle
will not fall.

Answer this.....

First some background. For times of bad weather they make a device you
can put your bicycle on to "train" indoors called "Rollers" They
consist of three rollers about 18 to 24 inches long, 2 are close
together and the back wheel rests between them the third is positioned
under the front wheel. See photo here....

In this situation the bicycle is obviously not moving forward. How does
it stay upright?

A bicycle is an open loop unstable "plant" that is stabilized by an organic
neural net closed loop controller.

Some aircraft are like that too. e.g. taildraggers on the ground. (how's
that for an attempt to drag this back to an aviation related thread?)
