For fear of embarrassing somebody (admittedly there is only a tiny chance of them being on here) I will be vague about this spot.
On the way back from South Easts last night I came across a nodder on a very small MTB frame but who was absolutely tiny himself. His saddle was as low as it could go and he was unable to sit on it and pedal...he was out of the saddle for the two miles I was with him, only occasionally sitting down to freewheel as he couldn't reach the bottom of his pedal stroke whilst seated.
The chap seemed about the size of one of my legs. Full credit to him though, he was keeping a reasonable pace and seemed to be enjoying his ride. Seriously dude...get a smaller frame and you wont look back!
Damo?
