Does look way more comfortable than a regular bike seat. Plus, when cruising, ya can sit back and when pumping up a hill, can sit more over the pedals. Ideal, really.

Bobber seat but same principle. (for DIY)

I would check out moped, motorcycle repair places. Might get lucky and they are scraping some odd/old bike and sell ya a seat for cheap.
Dunno. Just saw there was nothing going on with the search and just throwing my 2 cents in.
Really is a good choice, me thinks. I hate the way banana seats look but same idea of range of seating...
