Called "The Beast," this hoverbike design was uploaded to Behance for the world to see. In the description for the concept design, he notes that the bike is powered by a radial fan, similar to those found in computer graphics cards (GPUs) or "older hairdryers from the 70's." Kersten said that he "Liked the idea that on powerful fan could lift and move the vehicle." Aiding the bike's directional efforts are wings on the bottom, as well as two big thrust reverse brakes.
If the motorcycle from the movie "Akira" was a hoverbike, I'm sure it would've looked similar to this. Be sure to check out Kersten's Behance page for more amazing digital designs.
