The wheel guards are provided as an optional add-on for families with small children present. We recommend installing these since they help prevent small fingers from getting pinched between wheels. However, families with older children may choose not to install these wheel guards.
CHiP has been designed to work with or without the wheel guards.
In order to install CHiP's wheel guards, you will need the 8 screws that were included in the CHiP box, in order to hold the guards in place.
