Beautiful explanation sir. But, as in the example of the reversible efficiency of engines being used to describe thermodynamic properties, can you build a bicycle that will Not stay up to prove your principle?
More seriously, wheels on the same axis -- no moment arm in the yaw axis, or more accurately, no torque can develop along the moment arm between the wheels along the axle offset, because there is (virtually) no frictional resistance in their line of roll.
No matter how fast they spin -- you will still face plant (forward moment from induced friction torque in the wheel axis. So buy a face guard.
And engine efficiencies are not reversible -- unless you have a pocketful of anentropy.
