In 1896 Mikael Pedersen applied for a patent on his own way of molding the frame. The tubes were closed at the ends and placed in the bottom bracket. The frame got burnished and lowered into melted metal that tin soldered (soft solder) the frame and this secured rigidity and stability of the frame. The alloy of the melted metal is unknown today.
The frame was covered with a layer of copper, then a layer of nickel and then burnished again. In the end the frame was enameled in different colors. All in all a very good work of quality.
In 1911 there were six Gents models, two of which were "Diamond framed"; and 5 Ladies models, where two models also were "Diamond framed". These bicycles could be supplied with a 3 speed gear.
There is some disagreement as to how many bicycles were produced, some say 30,000 pieces, others say 8,000 pieces. Mr G Hall of Gloucester has made a research in which the highest frame number he could find was no. 7800 (see the frame numbers page).
The Head Tubes Assembly.
Mikael Pedersen invented two different "head tubes" to support his front-fork. One for ladies frames and one for gents frames. Why he made them different I don't know.
Later he made a "head tube" with a ball head, I assume he got the idea from the Cream separator.
