tl;dr: interesting and shows promise, still more work to do.
edit: don't be scared by the not-a-paywall greyed out text and box.
On single-speed bikes and common derailleur type multi-speed bikes (yes, even with freewheeling, but I assume even more without it) there's a very direct linkage between pedaling and movement. You start moving pretty much the instant you put pressure on the pedals.
I've noticed on some hub-gear bicycles there's a significant amount of slack where you have to pedal without resistance for at least 1/8 of a revolution until the drive mechanism kicks in. This is very frustrating to me (again, I'm sure it's only me...) and completely disrupts the suspense of disbelief I otherwise can conjure, which seems to be what allows me to get that freedom feeling almost like I'm flying. The lack of feedback for that fraction of a second yanks me straight out of the flow of navigating traffic with the bike as an extension of my body and reminds me sternly that I am sitting on a very-separate-from-my-body mechanical horse, some aspects of which are very much not in my control.
That sense of freedom is definitely one of the major reasons I use the bicycle as my primary means of transportation.
Sorry, very long rant about something very unspecific but vaguely related.
