I cannot recall if anybody had posted images of the Brompton side by side with the Helix when both are folded, but if it helps anybody, here are some images of the two together. NOTE: The seat of the Helix can go down MUCH further, and would be virtually at the same level as the Brompton when both bikes are in their folded configuration.


I left the seat up on the Helix because: 1) my removable bottle holder on the top tube is in the way; 2) the quick release back rack is in the "out of the way" position; and 3) I was too lazy to pop the seat down and then try to remember my ride height later! So, in the images, don't let the seat height trick you into thinking the Helix is fantastically larger than the Brompton: larger by a bit, yes; by that much? - no.

And yes, the garage door could use a new paint job....
