Why don't I see more bikes with a front-mounted motor on a 20" wheel?

Here is a link to a page with a pic of a postal bike. It has a small front wheel to allow you to carry the front cargo lower.

yeah, that sucker is $699.00!!!
you could buy a small motorcycle / moped for that much.

Yes. Surly's are very expensive. However, Schwinn made similar bikes for years and you can occasionally find them on craigslist for under 100 bones.

70lbs directly over the front tire and a front disc-brake... I wonder how many newbies went over the bars with that.
