Q factor like Jur says is something that gets me between bikes, too. Distance between the two inner pedal edges between the different bikes?
One think I notice when I look down at my feet is how far forward the BB is and hence the pedals relative to say my road bike. This is partly because I have the saddle as far back as it will go (seat clip to rear, far back on the rails) and partly the Brompton design with a long angled seat tube.
My shoes are a bit chunky trail walking shoes, and with the possibility of heel stike on the coaster wheels, it may be that I am putting my feet wider apart than I should. Perhaps riding clipless would help improve things here, certainly worth a try if I can get the pedals off (RHS was stuck firm last time I tried!).
