Just received this concept model from Alan Ball. Rory, Bill and Alan will have an online design meeting tomorrow to discuss this new approach. We have moved back to a more "planar" and more bike-like frame with single tubes. One wheel is hidden to reveal the frame.
Here you can see the "fork" apprach to what we used to call "twin flanking members." These forks let the frame overlap, and allow the morphing to go lower, for good distance riding stability and cornering.
Low rider mode. Not sure about the curved sections. They could be hard to fabricate. But this is just a concept model.
Wheel and seat removed, and you can see how the fork allows the main tube to morph lower without interference.
Here's a look at the previous design, which spead the frame members out to the sides. Better for strength, but many more parts, more metal, and it loses the bike look. That's way we went to this design, that combines the single tube look with the forks that give us our flanking members.
