Cannondale’s CERV Futuristic Bike Morphs with the Road, Forgoes the Fork and Chain (pics)
A traditional bike incorporates a chain that connects to a crank, which ultimately powers the back wheel. Furthering that is a set of fixed handlebars and a fork that rotates from left to right for steering. The Cannondale’s CERV (Continuously Ergonomic Race Vehicle) concept bike is anything but the aforementioned setup.
First off, the handle bars automatically adjust relative to the angle of descent or ascent, all without changing the seat to crank distance. When descending a hill, the handlebars moves forward and down to give the rider a low profile. Conversely, when climbing they move up and back for a more upright position, and when on flat terrain it’s somewhere in between. But because of this unique handlebar setup, Cannondale engineers had to opt for an unorthodox fork. In fact, the fork is devoid from this setup, as steering is translated from the fork to the front wheel. Further eschewing the traditional bike design is a chainless crank that seems to translate energy directly to the rear tire, which is paired with a futuristic transmission design that we’re not going to even begin to try and explain.
