Mengshen MS-Z12Black Bike Lock with Remote Control and Anti-Theft Vibration Alarm: Remote control or password locking/unlocking with 131 feet range
This bike lock is for the rider who wants to secure their bicycle at a busy rack or outside a coffee shop. It goes beyond basic theft prevention by acting as a personal security guard for your bike.
The remote control lets you arm the alarm from up to 40 meters away, so you can walk into a store without looking back. If someone touches your bike, the 115dB alarm sounds immediately. You hear a sharp alert before you even see the motion. The IP55 waterproof rating means rain won't stop it from working, and the low battery indicator flashes clearly so you never get caught off guard.
Use it on motorcycles, gates, or strollers for versatile protection. The password backup ensures you can always unlock it, even if the remote is out of range.
