brompton, seat question?

on the brompton, once i set the right height of my seat, when i fold and unfold it, do i need to center it each time and then mark the seat post to make sure it's always at the right height? or is there some initial way to set this once and then that's it? in videos when i see people unfold it it looks like they just pull the seat up and lock it down. they don't look they are making sure it's centered and at the right height, etc. is this correct?

this was one thing that bugged me about my old dahon boardwalk d7 was having to fuss with the seat/bar height/centering each time. even though i had drawn a line on the seatpost / handbars.

thanks

Telescopic seat post that it is, I have a general Height I'm Used to,
and pull it up to that height,
relative to the height of the bars, which are not height adjustable.
or, standing next to it it hits my hipbone in the same spot.
then, ride it and if it doesn't feel right stop and adjust it.

or just leave it up ,
and fold the other points just to take up less floor space..

Now if you buy a Bike Friday Tikit, because their seat folds forward,
rather than slides down,
the saddle height can remain a constant. (+ all those custom options.)

I know I'm resurrecting an old thread here, but I'm considering a Brompton and trying to gather as much info as I can.

Has anyone tried putting a collar at the bottom of the post so that it acts as a stopper when you pull up?

It would be even better if Brompton put a notch at the bottom of the "seat tube" and a tab on the post so that it was self centering.

Duh. The tab on the post would need to be moveable. I guess the solution would be just the notch and a custom tabbed collar (sort of like a seat post collar) that you could move up and down to set your saddle height.

you could run a cable from the bottom of the frame, up inside the seatpost
and out the top.

adjust it so when you pull the seat up the cable pulls tight.

will have a loop of slack cable when you put it down, though ..
careful you don't trip over it..

Permanent marker pen - I like Staedtler but I guess Sharpie would do just as well.
