That Jivo has a clever fold - that's not something you come up with over a coffee. Long design hours were spent. I can see some very clever things in the fold.
Yes indeed, but then Dahon probably has a larger in-house R&D resource than the rest of the folding bike industry put together. It looks to me like the design brief given to the engineers may have been 16" wheels and an upper limit on the folded package volume, to meet what would be a fairly obvious marketing goal. I'm just not sure we will come to love that longitudinal hinge, assuming that the picture shows the actual production model and not a prototype.
