A full replacement wheel for your Skikes!
First remove the plastic cap with a screwdriver or claws. Unscrew the desired axle screw with the standard skike socket wrench. Push out the axle screw. Put the new axle screw in direction which is printed on your skike (left or right) through frame and rim. Put shim and nut onto the screw and tighten. Finally tight the screw and put back the plastic cap.
Check the proper assembly of all components before you use your skikes again.
