Item Includes: 1 x Phone holder for motorbike / bike handlebar (Please find the item photo for instruction of set up)  Usage notice: Please tighten up the screw of the handlebar holder before usage, to fix the position There is a design of the button at the middle of the holder for auto-lock. Please simply push your phone thru the holder until the button is touched, so the holder will automatically lock up your device. To release the phone, please simply slide the side button towards middle. Please hold your device to void dropping while releasing the side button.  The color of the item is FULL BLACK.  The maximum thickness for this holder is limited at 1.8cm.
