Also, not sure if you concept would even work. I'm not a bike designer by any means, but looks like the bend of the sections is opposite to what it should be to be under tension so your would just collapse on itself.
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.
Maybe look at this topic: viewtopic.php?f=5&t=24997
If it was inspired, then that means that someone thought your idea was good and decided to push it forward!
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.
