Each long-lasting black wheel comes with the bearings and spacer pre-installed to make it easy to upgrade your ride. For the Maxi Kickboard and Kickboard Compact.

To install:

1. Use two 1/8 Allen keys. Insert one into the screw side (which is completely round) and one into the bolt side.
2. Hold the bolt side still, and turn the Allen key in the screw side counter-clockwise until it loosens. If the blue lock-tight glue used in the original manufacture is still in place, you may need to use a little muscle to loosen the screw.
3. Pop the wheel out, replace it with a new one, and reattach the screw.
