geeky bike physics

Stumbled across this today. What happens if you tie a string to a bike pedal at the bottom of its travel, and then pull backward on the string?

There really is no end to my bike geekiness; I loved this.The original article is here, but the sound quality wasn't as good, and the video took FOREVER to download, with much buffer-overrun pausing.

I will take credit for making a correct guess that the outcome would depend on the gearing, but I had no idea that the gearing difference would have to be so large to make the difference.

(Between rain and family obligations, probably no group ride this weekend, and I'm looking for bike-y stuff to assuage my disappointment.)
