This looks cool, before delving into adjustment details:

For the folding aspect of it, this provides no more function really than a flat bar with bar ends. You need to turn the hex bolts to do any "folding", so folding isn't really what this should be called. You could do most of the same folding with the bar ends and rotating the bar in the stem, or removing a faceplate, removing the bar, and turning that.


Thought from first look that maybe they had a cool button to press that lets you go from the chosen angle to getting the bars folded inward. You'd have 2-4 hex bolts to undo a stem face plate, and 4 bolts here on their handlebars.
