I am not sure that it would collapse, but I do agree that the construction was not worked out in my sketch concept. The bend around the bottom bracket in my drawing is too tight,and there are there are many other issues that would have needed to be addressed if the design had been developed further.
That is a good point, and I do agree. If the sketches did spark this new design though, I would just like to know. Either way, I am glad to see the idea as a functional prototype.
…and thanks for that link. Very interesting.
Thanks to both of you for the comments.
