Huh?  The experiment is about experiencing.  Try it, hold a bicycle wheel in your hand while it&#x27;s spinning and turn it, and then come back.  My point was gyroscopic effect are absolutely noticeable at bicycle speed and wheel sizes&#x2F;mass.  Try it out, come back, and tell me what you&#x27;ve felt and what you think is the physics behind it.<p>I didn&#x27;t stay bicycles stay upright <i>because</i> of gyroscopic effects.  I said they are more stable at speed and that I&#x27;m pretty sure that&#x27;s due to gyroscopic effects because all else is equal.  Do you think bicycles and motorcycles are more stable or less stable at speed and why?  None of your very interesting links (I did see one of them before) add any relevant information.<p>A quote from your link supports what I said: &quot;It is almost certain that gyro effects are important at the initial stage of steering manoeuvres.&quot;<p>You say: &quot;the gyroscopic effects that everyone mistakenly believes are present in bicycle tires&#x2F;wheels.&quot;
