Ever forget where you parked your bike? Well, okay, maybe we’re in the minority, but sometimes you just need a little extra help, and the LINKA Smart Lock is one solution. Soon to be available, this is more than simply a way to secure your bike. It has a built-in, super loud siren (think, car alarm), auto unlocking when you approach your bike, a bike parking locator to remind you where you parked your bike, and even a theft indicator map that warns you about potential problem areas for parking your bike. This battery-operated locking ring is mounted directly to the rear brake bridge of your bike and weighs less than 500 grams. A smart way to lock your bike!
