This is a new, unused item that I have kept in storage since purchase. I imagine many of you have been looking for this! The product description is as follows: Introducing the Nokē (Nokey) bicycle U-lock, equipped with various smart features compatible with Apple Watch and other smartwatches. With this U-lock, featuring a built-in alarm, a fully functional app, and a nearly unbreakable body, locking your bicycle and sharing it with friends has never been easier or faster! Using your smartphone's Bluetooth Smart connection and the Nokē app (iOS, Android, or Windows Phone), you can easily unlock your Nokē U-lock with the touch of a button. This is an innovative device where your smartphone acts as the key to your bicycle lock. With a single press of a button, it activates and begins searching for the owner's smartphone or the smartphones of those with shared access. If the smartphone is within a few meters, Nokē unlocks instantly. You can start riding smoothly. There's no need to restart the app or take your smartphone out of your pocket or bag. If you want to further enhance security, you can disable the auto-unlock function and choose to unlock Nokē only through the app's button operation. If a suspicious person tries to pry open Nokē for more than 3 seconds, an alarm will sound. This will deter the suspicious person and attract the attention of people within 50 meters. You can grant one-time access or custom access rights based on specific days and times. Even if you forget where you parked your bicycle, the Nokē app has you covered. Each time you turn on the Nokē U-Lock, it's marked, so you can locate your bicycle.
