Take the 2-minute tour ×  I have the black mounted lock you see
below, and would like to buy a U/D lock or folding lock, so the
bike can't be moved. I would prefer a 12mm wire where one end
goes into the mounted lock, but many videos suggest that they
can be cut.  There are lots of videos on YouTube, where they use
a grinder to saw over the locks, but I am not so concerned about
these types of attacks.  Below have I found an U/D lock, which I
have no idea if this particular model is good compared to an
Abus or Kryptonite of similar weight, but I like that it also
functions as a luggage carrier.   How concerned should I be
about the leverage attacks, as this U/D lock is fairly long?
Which strengths and weaknesses does U/D and folding locks have
compared to each other?  enter image description here enter

(Abus Bordo is marked as a silver Sold Secure Lock), but the
price doesn't make it seem worth
