This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

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 immobilize 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.
