The lock is installed and attached to the scooter and fastened to various static objects by flexible steel deadbolt (6mm) to prevent theft of a scooter or bicycle.
The lock is used to fix a scooter or bicycle to a fence, tree, road pole, etc. When the power supply voltage is applied to the lock, the cable "shoots" out of the lock and the person immediately sees that the lock is open. This allows to move freely and leave a scooter in different places, securely buckling it and not fearing for its loss. This solution also allows the owner of a scooter rental business to securely fix scooters in a parking space.
