NUNET N40116450 Gray/Stainless Steel, 71 inches Bluetooth Bike Lock with Alarm
Available Options
For the cyclist who wants to secure their bike, scooter, or motorcycle without fumbling for keys, the NUNET NULOCK offers a smart solution. This lock is ideal for daily commuters or weekend riders who need quick, reliable protection. While many locks focus on theft prevention, this one adds a layer of convenience that simplifies your routine.
Connect the lock to your phone via Bluetooth for keyless control. The app alerts you if someone tampers with your bike, with a 110db alarm triggered by vibration or cutting. In practice, you might get a notification on your phone before you even hear the alarm, giving you a head start to check on your gear. The 71-inch steel cable wraps around multiple bikes or secures items like patio furniture, and its waterproof design handles rain or splashes. With a low battery warning in the app, you always know when to replace the AAA batteries, ensuring it's ready when you are.
