I'm just trying to think back to physics class. The total amount of energy is the same either way, but you either spin faster or mash harder. It's the mashing on a high gear ratio that pulls the wheel out. If you put your road bike in the same ratio as your SS/FG, you should experience the same thing with the wheel coming loose.
it's not the gear ratio it's the size of the rear cog. If you use a large cog you move the mechanical advantage to a place where the wheel won't get pulled out.
