An unusually well- executed homebuilt LWB bike with a complete fairing seen in Farum (buider a German, name sadly forgotten). I dare say a fairing that's fairly[sic!] cheap to build as well. It is held up by a specially curved aluminum skeleton attached to the bike frame. The transparent body is made of a single  1 mm (or perhaps even less) sheet of polycarbonate (trade name Lexan, among others), which has been stretched over the supports and Pop- riveted in place. Polycarbonate is a polymer with extremely- long and stable molecular chains, which make it practically unbreakable. It is also rigid enough for that kind of enclosures.
    The above-the-front-fork part of it has been intricately cut in zig- zag fashion, and the resulting outward- pointing triangles bent down, and fastened to one another. In all, a very nice fairing implementation, that must provide the rider with nearly- complete weather protection. My chief, though rather weak, objection to it has to do with it being transparent, ergo on sunny days acting as a greenhouse on wheels! ;-)). Still, perhaps the open --or, rather, lack of-- "bottom" makes it self- ventilating enough to consider it a non- issue.

    In the background, an orange early- model  Leitra,  recognizable by its petite fairing size (builder/ inventor Carl- Georg Rasmussen is a small, wiry fellow), and the afterthought pea- like- rear- mirror housing atop the cabin.
