I generally don't like concept designs as they tend to be incredible good to look at but appear to be incredibly impractical in the real world, and generally are not much more than a chance for a designer to indulge their own fantasies.
But I make an exception for this bike.
It is a very funky looking concept bike that appears to have integrated rear lights and an integrated locking system (although why you would ever want to lock it up and let it out of your sight is beyond me...)
Not entirely sure about the integrated music player though. I'm not a fan of listening to music when cycling, but I guess that's just personal preference.
