I think you should also consider the comfort.
And I doubt that Helix is a comfortable bike.
It has no suspension at all, the lefty fork will be very stiff, the rear triangle will also be stiff and the tires are relatively narrow+ high pressure (no possibility to mount balloon tires like the Big Apple).
I think that even if it has smaller wheels, a Birdy will better fit your needs: full suspension+balloon tire, fully adjustable seatpost and stem (in height + two types with two different tilt to be chosen depending of your height).
I had an opportunity to test ride a Birdy 3 with the "comfort stem" about 18 months ago. I agree with everything that you've written about its fit and comfort. By the time I came to the point of finalizing a purchase decision, unfortunately, my local bike store owner had decided to discontinue selling+servicing them. That, and the fact that loading the somewhat awkward shape of the folded Birdy package into my car proved to be difficult for me ("bad back" limitations due to having had most of my vertebrae fused) has caused me to back off. (If I were to change my mind I do know how to purchase the Birdy from New York and Singapore, but that would not alleviate my other concerns.)
Still, I appreciate very much your comments.
