I bet your bike lock is not as cool as the LINKA. This is a smart bike lock that unlocks as you approach your bike. The lock features a 3-axis accelerometer that detects movement of your bike and sends you an alert. It also has a 100 dB siren to keep thieves at bay. You can control your bike lock from your smartphone. The 9mm thick hardened square steel ring which locks your bike makes it impossible for anyone to ride away with your bike.
The LINKA also lets you enter a 4-digit passcode to unlock it without your phone. The companion app runs on iOS/Android devices. Even if your bike is lost, you can rely on other LINKA riders to track your bike. Did we mention that the battery lasts up to a year? You can find this product on Kickstarter.
