As a long-time cyclist the first thing I notice are the brakes
, or lack thereof!
I'm assuming that there's a back brake, but as with all wheeled vehicles most of the stopping power is in the front. I'd love to see this concept executed with more state-of-the-art materials and design parameters. With the use of Carbon-fiber shell and an aluminum or titanium frame the weight
of this thing could likely be cut in half! The use of modern mountain-bike disk brakes
, suspension components and drive-train could result in a machine that would be fun and (almost) practical to use for extended trips!
