Bolting your bike to a rack just isn’t enough to keep it safe. Of course, you can always throw in a traditional combination bike lock into the equation, but this will only delay the process.
A group of engineers from South Korea think they have the solution and that would be the Bisecu Smart Bike Lock. The lock utilizes a Bluetooth 4.0 chipset to communicate to the connected phone. It features a 100dB audible alarm, accelerometer, waterproof design, military grade encryption, gyroscope and patent-pending locking mechanism. If a thief tampers with the lock, an alert will be transmitted to the connected phone and the audible alarm will be activated. This will alert the owner and the people in close vicinity of the event.
