Chicago Grid | Track a stolen bike from your phone with Bike Spike

The Internet of missing or damaged things; if you're primarily interested in speed, route, and terrain data, I recommend (freemium) Strava

"What it is: Like OnStar for bikes. Contains a GPS and anti-theft device that alerts its owner if a bike is stolen or tampered with. After a collision, an accelerometer gauges if the impact was serious — if so, BikeSpike will alert emergency contacts and police. It also collects data on speed, route and the terrain of a ride, which riders can access through a subscription service."
