1) I already made the assumption that the wheel ideally sticks to the surface and there is no slip, which I think is quite accurate in such a low force high grip scenario. That also means that the belt speed equals the wheel speed.

2) If the bearing is frictionless no amount of orthogonal force applied can produce torque on the strut holding the axis therefore it cannot exert force on the plane. It is like pulling nothing. All the energy you put in will end up in wheel rotation.


To illustrate: Get a toy car put it on a movable flat surface, for instance a cardboard box. Move the surface. If you do it fast enough to overcome static friction (not ideal system like the plane!) the toy car will almost stay in place.
