Now this is cool: A small, discrete GPS tracking device that attaches to your bike and warns you if it has been stolen. Even better, it keeps tracking your bike after it has been taken, showing you exactly where it is. Even betterer, because it contains an accelerometer, if your you experience a drastic and sudden decrease in speed while out riding (in other words, you've crashed) the device will notify your friends that you may been in trouble. Oh yeah, and the developers of this nifty device are right here in little 'ole Chicago.
This brainy invention in called the BikeSpike and is doing very well on Kickstarter. Bravo!
