Picture the holding of the bike wheel while standing on the rotating platform scenario..... If you tilt the top of the wheel, you will be forced to the left or right... If you tilted the wheel to the left or right, would you feel an upward force or downward?
If so, why could you not build a levitating device using this technique?

All of your proposed experiments involve having the wheel anchored to/suspended from *something*. There is no lift or vertical thrust in any of your scenarios to suggest that a precessing wheel could maintain itself in motion unsuspended or unanchored.

You feel resistance to the move only- if applied force is to left or right- you get resistance - not a force back but a force countering yours at a reduced level of effort. NO actual new force that will allow movement- it there was -you could let wheel go and it would move up if it had lift. You are not creating lift here - just counter force to the efford you are producing to the opposite side. Make the inner spokes aerodynamic and you get a prop structure that uses air friction to get lift.
