If you care about your bike, you need the ZiiLock Foldable Proactive Bike Lock. Unlike regular bike locks, this one is loaded with smart features. Not only can you unlock it with a key, but ZiiLock also unlocks with your fingerprint and Bluetooth connectivity. In fact, the fingerprint takes just half a second to unlock the device. It can also store up to 20 different fingerprints. Perfect for commuters, all this technology folds down into a surprisingly compact size that can fit in your back pocket. Then, when it’s time to secure your bike, it unfolds into a 98-centimeter locking system featuring an unbreakable and temper-hardened material. With AES 256 military-level security, ZiiLock even goes a step further. If it detects a thief trying to steal your bike, it instantly notifies you on your smartphone. This active protection gives you total peace of mind. You can also use the app to drop a pin to save its location, share your bike with a friend with remote access, and more.
