Anyone who ever said that coolness is rooted in practicality needs to have a look at the EX trike, built by Nils Ferber, Sebastian Auray, Ruben Faber and Ludolf von Oldershausen.
This wire frame of a tricycle is crafted from bicycle parts, but instead of the rider pedaling it depends on two electric Bosche hand drills which can apparently propel it up to 30 kmh (~18mph). Turning isn’t quite as simple as propelling the vehicle, since it requires the rider to lean, which influences the back wheel to tilt in the desired direction. However, braking and accelerating are performed using a set of handles.
Wanna buy it? No dice.
