Drifft 6.5" Hoverboard Shell Replacement in White Graffiti Shell for your 6.5" Self Balancing Scooter. Our hoverboard shells are great for replacing your old scratched exterior shell of your balance scooter or even when you just want to update the color of your self balancing scooter without paying the high cost of replacing the entire 6.5" smart scooter. Changing the White Graffiti hoverboard shell is typically very easy for most people. To disassemble, all you have to do is use a cross screwdriver and unscrew the screws from the bottom of the hoverboard and detach the wires. Make sure not to lose the screws! Once you're done with this, there are 6 screws that connect the hoverboard to the frame. Unscrew those and your hoverboard shell should come apart.
