Nothing in the pdf scared me off but the weight does, approx 650 grams.
I think you missed my point - the "foldability" of a flat or other bar with bar ends is similar to the Humpert. You'll need a hex key for doing either. So why pay the premium? And it's a moot point - this bar won't work with Brompton without some other parallel connected stem such as Aber Hallo.
Hex bolts like this aren't made for hundreds or thousands of insertions/extractions. You'll run into problems. Even Humpert themselves recommend replacing (see the PDF) this at either the smaller of 3 years or 10k. It's not really listed in their design intent either if this is made to be folded constantly. Sure, do it occassionally, just like pull off normal bars occasionally with the same hex key.
