Default wobble/cranks/coker

While we are at fundamentals physics, I have a question he
IF the pedals of a uni where not fixed to the axle and transmitting
force thru
the cranks
but were fixed in a way more like those of an "impossible wheel"
(by a trick yet to be invented ... alongside a bar that goes from axle
to rim for instance -though I don't believe it would be a good idea- )
what would be the effect on riding?


Assuming your foot pedal position relative to the wheel is the same and
everything is sufficiently stiff then the effect on riding would be
negligible. The idea is clearly doable although creates a whole lot of
problems with almost no advantages. One could easily have crank arms welded
directly along the centerline of a hub in stead of bolting them to the
outside of the hub. They would just extending outward within the spokes.
But you need a long extension from the end of the crank to the pedal. This
is not where you want an extension. The leverage there would create a lot
of twisting on the crankarm. Nearly everything related to building or
modifying configuration would be more difficult.
