The Continuously Ergonomic Race Vehicle (CERV) is a concept based on Cannondale’s radical vision for a bike that was forkless, chainless, and dynamically adjustable. This was developed into a working prototype by Priority Designs, who created a bike that changes the position of the handlebars to adjust to different types of terrain.
The CERV features a dynamically adjustable headset that moves both fore-and-aft and up-and-down. The genius lies in achieving the above without altering the seat-to-crank height. This system puts the rider in an optimal position based on the terrain. The headset translates forward and down for a clean, low-drag position when descending. When climbing, it moves up and back, creating a more upright position for maximum leverage on the crank.
CERV was unveiled last month at the Eurobike exhibition and you can click through to see pictures of the bike below:
