Adjusting the seat height on my Brompton was really annoying at first! I can see how the Tikit's fold would be attractive in that respect. When I first got my bike, I actually drew a ring on the seat post with a Sharpie so I could find the proper height without fiddling, and that worked like a charm. A year later, I can "feel" exactly where it needs to be, within about a half-inch or so, without the aid of a mark. Very rarely do I under- or over-shoot and end up with an uncomfortable ride. It just takes a little getting used to.
