This is a dial lock that can be attached to an electric kickboard. 1.2m long dial cable lock. Compatible with handlebars with a diameter of 18-36mm. It's very convenient to carry as it can be removed from the holder with one touch by setting it in the included holder and pressing the button. Setting Instructions The initial setting is 0000. There is a knob labeled "SET" on the key insertion slot. Rotate it 90 degrees in the direction of the arrow and set your desired 4-digit number. Rotate it 90 degrees in the opposite direction of the arrow to complete the setting. Recommended for kickboards and bicycles such as Xiaomi and Ninebot. I am selling it because I haven't had a chance to use it. No instructions or box are included. Everything in photos 6-7 is included.
