If you've had your bike stolen before you know that finding it is like looking for a needle in a haystack. In case that happens again you won't run into the same trouble if you have the BikeSpike installed on your bike. It's a GPS tracking system with a built-in antenna, an on-board accelerometer, and a connection to a global cellular network. It does more than just track your bike when it gets stolen. It has a collision detection system that alerts selected members of your contact list and share the location of an accident, sends you alerts when your bike is moved or tampered with, and you can use to monitor your children to make sure that stay within the safe zone. With all this tech, it can potentially do even more.
