This proposed power transfer mechanic linkage can't handle angular differences between the power plant and wheel, so you would end up with broken mechanic linkages and torn shafts. Non-spinning-shaft power transmission (doesn't really need to be electric, could as well be something like fluid power transmission like hydraulic or pneumatic power) dodge this by putting the power plant in a way the angle between power plant and wheel can't change.
