a theft-proof bike

i used to live in holland where riding your bike was one the main form of transportation.  growing up i loved picked out my new bike and adding stickers to make it unique (i was really cool, i know)...well designer juri zaech came up with a new way to make your bike one of a kind.  aren't these bikes so awesome?  i have a friend who would die die die over the yellow one, if only i was a millionaire and then i could get that for her birthday.
