Wrong. The gyroscopic action is all that a bicycle needs to be up right.
Since the bicycle is not accelerating, but travelling at constant speed, no
force acts upon the bicycle, right ? (except gravity, neglect friction).
So, why doesn't the bicycle fall under gravity?
The bigger the bicycle speed is the less the bicycle will trend to fall.
Is it magic? (since no force acts upon the bicycle at ANY constant speed).
It is not magic, it is called gyroscopic effect.
