TIRED of bending down to lock your bike? A team of South Korean engineers have developed a small circular device that is installed on the hub of the front wheel and is connected to the owner's smartphone via Bluetooth.

When the bike owner stops riding and walks away, the device automatically locks itself. When the rider returns, it detects that too and will unlock. Any thief who tries to ride off with the bike would find the front wheel frozen in position.
