Gyroscopic effects of wheels on a bicycle debunked completely

Turns out the gyroscopic effect has no effect whatsover in keeping a bike upright, contrary to popular belief.
It apparently has to do with the higher center of mass in the back relative to the front, which allows a falling bike to steer in the direction of a fall, and thus helping it stay upright.
Published in the most prestigious scientific journal (Science).

What was their explanation of rollers?

Without having read the science article itself, it seemed that the additional gyros placed above the wheels counteracted the gyroscopic effect. So it actually is a bike with no gyroscopic effect.

I like Gyros they taste really good. -

Take a bicycle wheel and an office chair.
Get the wheel rotating fast. Hold it vertically as it rotates. Lift you feet off the ground while seated on the chair, wheel spinning quickly in your hand.
Turn the wheel horizontal.
Incredible, isn't it.

Removing that factor from their experiment only shows that their explanation holds true. It doesn't mean that the gyroscopic effect is also false... see what I mean.

Conversely: try rolling along on your bike on an icy road, then lock up the brakes and note the difference in balance.Actually don't try that unless you enjoy falling

I used to practice rolling the mx bikes front wheel up on a sheet of plastic, grab some front brake and see how long I could ride it. (Its good practice for mud races) -

And if you wanted to take it further, a motorcycle will NOT turn until you counter-steer it. Proven by the "No BS bike" at Kieth Code's racing school. It's a race bike with a second set of handlebars welded to the frame, so that it debunks the myth that you can turn the bike by leaning it. People will lean, finesse, and torque it all day and it WILL NOT turn. So... When you add more mass such that the gyroscopic effect is greater, it takes over completely.
