The Inner City Bike has a Simple Frame and Tight Tires

It sort of looks like a bicycle and seems to ride like one, but the Inner City Bike has no chain and has an extremely minimal frame.

Taking on a very simple geometric form, the Inner City bike is essentially a top tube frame joining the fork and the stay. With inconspicuous handlebars and no tress support, this cutting-edge two wheeler looks more like conjoined unicycle twins than a traditional bicycle.
