Dieter F from Germany wrote about a Max skatebike he had.

I own a Max skatebike since the 80ties. It was the demonstration model of the windsurf shop I helped out during my study times. I took it everywhere with me and used it in Germany, Korea, India and China. It finally showed a lot of dents and rust and so, when I had the chance in 2020 in China for powder coating I made a refit. We even made a tool to press new rubber for the skateboard steering. The former plastic upper skateboard truck I already replaced in the 90ties with a CNC made alloy part.

Here is the label Dieter drew to have a new seat post sticker made.
