I'd check out these brands:

Linus http://www.linusbike.com/models/

Public Bikes http://publicbikes.com/Bikes

I'd also think more about why you don't want a folding bike like the Xootr Swift. They are super convenient and you can just bring it with you after your short rides rather than locking it up. For short rides, it's way faster and more practical than anything else (for me).
