Gyroscopic effect is not even significant. Lock your steering and you will fall over no matter how fast your wheels are spinning. (Which can happen with a badly pitted headset)

Same principle as a gyroscope: a turning wheel will tend to stay perpendicular or parallel to the direction of the gravity vector because if it starts tilting away from such orientation there’s a force that pushes it back to that orientations.
Also works better with bigger wheels (if I remember it correctly the effect is related to spinning momentum).
I was pretty surprised when learning Physics and they show us how to derive the formula for that (which I totally forgot since that was over 3 decades ago).

Actually, it’s the bike’s geometry rather than a gyroscopic effect. Try rolling a bike backwards rather than forward - it’ll topple quickly

Yeah, you’re mostly right: Why bycicles stay upright.
There’s some gyroscopic effect, but per that article it’s not the main reason.

Yep. And it is an easy one to test. Just inmobilize the bike’s steering and see how well you can get it to balance.

Freestyle BMX riders go in reverse all the time and they don’t fall over.

A BMX bike without a rider will roll along happily. We called it “ghost riding” when I was a kid.
