If you've ever been the victim of bike thieves, here's one Kickstarter project that should pedal up your interest.
The BikeSpike is a subtle way to deter bike thieves by looking like a regular old water bottle holder. However, that bottle holder hides a unique little trick: a GPS tracker that syncs to your smartphone. Beyond letting you know where your stolen pedal-based conveyance is, the BikeSpike also has more practical everyday purposes for bike riders such as calorie counters, distance measurement and even collision information should a cyclist be involved in one.
The idea of tracking bike thieves without them even being alerted to that fact is an impressive and futuristic way to catch criminals in the act. The idea of hiding GPS trackers in valuable property is likely one that will be seen in many products moving forward.
