Earlier this afternoon, Cyclelicious posted about a Cannondale prototype from Eurobike that looks a lot like a chain drive version of the foldable Jackknife concept bike. You can find out more about the prototype on the Cyclelicious post and also see the prototype here, here, and here.
I am hoping to find out a little more about this bike and I will update the post if I do. I bet we will see several other urban oriented designs like this as Eurobike continues.
Update 8/31: Cannondale now has an article on their website about this urban bike prototype, called the “ON”. The article explains what inspired the design and includes several pictures and sketches (like the one below). Check it out here.
