I only know of 2 metres max but wouldn’t you be better off with more than one lock and just the one to the anchor? With the one lock once that is gone you can have the pick of the bikes. With several you might be able to remove the one from the wall anchor but you still couldn’t move 10 bikes in one go. Thats the way i’ve always thought, know it takes longer to lock and unlock and it’s a bit of a PITA but it’s a lot less trouble than saving up for 10 new bikes. Also recently lost keys to my bike with two cable locks on and it took less than five minutes to remove both with a not very good hacksaw, good make locks as well.
