From the material’s soft touch to the movement of the dial when locking and unlocking—the supple cover makes a gentle pop when you reverse it.

Turn the soft cover inside out to lock your bicycle, and reverse it when you are done. Slip it in your bag or pocket, without worrying about the unit staining.

The coiled wire simply slips into the soft case, relieving you of the hassle of winding up the chain when unlocking your bicycle.
