That's what I'm saying. I'm not a flag-waver for the big brands, but diverging seatpost and handlepost, for a bike that adjusts to a wide height range, was pretty smart. Wish I'd've thought of it.
The one-piece monobeam frame is simple and stiff, but due to its short length for compactness, I think that is the rationale of the horizontal stem projecting far forward, then handlepost up and back; I think they need that for knee clearance when climbing out of the saddle, versus a straight vertical handlepost that far back. The very slack head tube angle helps project the front wheel out further to restore some wheelbase lost to the short frame.
