I Lock it locks and unlocks your bike automatically using Bluetooth low energy technology. So no more pulling out your keys and struggling with your bike lock, you can just leave your bike and be sure it's safe. I LOCK IT lets you enjoy life without the need to think about keys or bike locks. Just get on your bike and ride. When you get off your bike I LOCK IT measures the distance to your smartphone. As soon as you walk away from your bike I LOCK IT will move a 64 mm² thick stainless steel bolt through the rear wheel. This immobilises your bike and prevents theft. With I LOCK IT you don't have to pull out your keys or press any buttons. You can just walk away and be sure your bike is safe. While automatic locking is a great feature you can also lock your bike by using your smartphone or by pressing the button on I LOCK IT. This gives you the flexibility to choose how you want to lock your bike. An alarm works just like your car alarm and is automatically activated when I LOCK IT.
