Bike Hugger Bettie
Bettie is Bike Hugger design study in urban mobility focused on building a sport-utility bike. A sport-utility bike (SUB) is a variety of load-carrying bicycle pioneered by Xtracycle who invented the FreeRadical, a hitchless bike trailer (it attaches directly to the frame instead of with hinges).
Wikipedia thoroughly explains the Xtracycle in an entry, including their history, and even links to Bettie.
We blog all about Bettie on Bike Hugger, a Hugger Industries blog.
