And...just because there isn't an answer doesn't mean it's not worth discussing.
I'm not sure where this Azor vs. Velorbis geometry argument really came from or what the motive behind it is, but I will say I have only heard it from one dealer. That dealer posted it here as a comment when I was making my decision and shares that opinion with prospective buyers who contact them. I respect the dealer and their opinion - but I disagree.
Having ridden 3 Velorbis bikes - 3 different models, I can confirm that the Velorbis is a completely upright riding posture when the seat and handlebars are correctly adjusted for your height and inseam.
There is no leaning forward, there is no weight on the hands, one's back is completely straight while riding, the center of gravity is on your seat.
The Velorbis (red) and Henry WorkCycles Azor (blue) frames, superimposed. Note that the frames are exactly the same, the only differences are that the Velorbis seat in this photo was set higher and the hub of the rear wheel is slightly further back (this is an adjustable difference on the Velorbis, not part of the inherent frame geometry as it is on the Azor). There is no difference in the distance or angles between the seat post and pedals, the seat post and handlebar stem and the pedals and handlebar stem. If you choose an upright riding posture - adjusting the seat and handlebar height and tilt will give you this posture OR not, on both an Azor frame and a Velorbis frame. I'm a rider, not a technical bicycle person, so forgive my incorrect labelling of the parts - but you know what I mean, so get over it.
I've ridden bicycles in Denmark, France and other places in Europe over the past 17 years - and all the bicycles I chose to ride were upright. There is a trend toward leaning forward slightly for young men, and this is occurring all across Europe. Because of this trend you will see some Velorbis riders who are choosing to raise the seat and thereby lean slightly forward. But that doesn't reflect the frame geometry. Rather, it reflects the way the seat and handlebars have been adjusted and the size of frame chosen by the rider.
There are many reasons to choose an Azor over a Velorbis or vise versa, but frame geometry just isn't one of them.
When I was trying to decide on a bicycle, I spent months doing research. I would suggest anyone trying to decide on a bicycle contact, by email, all the different dealers and bike shops you can find, both in your hometown and abroad - ask them the same questions and compare the responses. Once you've done this - you can get a good sense of which shops and dealers prefer which bicycles.
I contacted bicycle shops, dealers and manufacturers in Copenhagen and Amsterdam, New York, Vancouver, Portland and more - asking for all of their opinions. When they all shared an opinion, I considered it pretty likely to be true-ish.
And above all, don't forget, guys and gals in bike shops are people just like you and me - and they have personal preferences, likes and dislikes, etc. Keep those in mind and don't forget about your own preferences and likes and dislikes when you're listening to theirs.
If you want an upright bicycle - get a Gazelle, a Batavus, an Azor, a Velorbis or any other upright bicycle - they're all upright, they're all (most models) sturdy steel frames and they'll all get you there in style.
