I had a go on one of the bikes from http://www.cytronex.com/ at an 'eco transportation expo' last year, it was a lot of fun to ride around a carpark on, and didn't look any different from a normal commuter bike except for the massive front hub.
They're not my cup of tea, but for elderly/partially disabled, even lazy people! I think they're a really good idea.
