Nereus is an innovative concept by designer Mathias Koehler, which combines a water bike with a paper kite. The control of the vehicle is assured by two pedals, while the handlebars allow the Nereus to perform its most notable feature: its ability to submerge. The immersion, however, is short-lasting, as the vessel's light structure impels it to the surface.
The navigation aboard the Nereus is bound to be exciting and fun, especially while facing the wind, in zigzags. Imagine a dolphin's movements and you'll have a close idea of how this cutting edge vehicle moves. Only one question, which is also a fear: how do you stop this thing?
