Cannondale’s CERV bike dynamically adjusts to changing terrain

Developed into a working prototype by Ohio-based Priority Designs, the CERV is based on a concept from Cannondale that called for a design that allowed the handlebars to move up and down without altering the distance from the seat to the crank.

The answer was a triangular frame with 100 mm (3.9 in) of travel up and down that moves in relation to the front end’s 85 mm (3.3 in) of travel forward and back.

The curved drop handlebars long found on racing bicycles are pretty nifty, right?

If you want to get down low to reduce your wind resistance you grab hold of the lower part, and if you’re climbing a hill and need to get a bit more weight and leverage on the crank you can shift your grip to the top bar.

The Continuously Ergonomic Race Vehicle (CERV) concept bike takes things a step (or two) further with a design that dynamically adjusts the position of the handlebars based on the terrain being covered, all without changing the seat-to-crank height.
