SUP board simple trolley

Simple trolley for paddle board from kid's training wheels.
This is suitable for the most versions of the training wheels with 22mm wide frame and M10 bolt. The trolley is attached to the board with 1"/26mm wide strap available almost everywhere.

Mount training wheel to the mount with M10 30mm bolt and locknut. Put the strap through the slots in the mounts. Put trolley mounts on the board and tighten the strap.

Take a note that these mounts are designed to be on the 10-degree curve. So move the mount along the edge and find the spot, where wheels are pointing straight forward.
