Depends on how long your seatpost is, with the extended one you should be fine, standard one not sure you’d be able to push the seatpost down all the way to lock the fold, with that on there.
Also need to take into account the pentaclip at the top...
Thanks! Hadn’t seen many photos online as I don’t have an extending post. But it’s an old Brompton and I seem to have c.10cm of post to play with before I can no longer lock the fold.
