Bike company Fortified Bicycle is currently trying to raise $100,000 on Kickstarter to manufacture Invincible, its new "theft-proof" bike. Although nothing is truly theft-proof, of course, the bike does come with a lot of cool features that will hinder thieves—all the parts are locked together with custom-made bolts, and there is apparently a team "monitoring secondary markets and working with local law enforcement." Also, if you're bike does get stolen, they will ship you a new one immediately. Also, it comes with a really nice lock.
