Interesting concept ...
HMK 561 electric bike concept seats you on the battery, makes you significantly more attractive

Most electric bikes are fairly sordid affairs, little more than an ordinary bicycle with a motorized hub, a strap-on battery pack and regenerative braking capabilities (if you're lucky). Not this HMK 561 electric bicycle concept, which took home an iF Design Award for some seriously forward thinking. It's not just the stylish forward rake of this juiced cruiser that's innovative, it's the frame -- composed completely of a conductive carbon fiber weave that allows the bike's body to not just pass electricity to the motors, but actually store it like a giant capacitor. Factor in integrated lights and a pinch of that aforesaid regenerative braking at each axle, and you've just about got the bicycle of our dreams. Oh, and did we mention a prototype has already been built? Yeah.
