There are 5 jump cuts in the sequence to demonstrate the lock feature in the promotional video and it is only demonstrated once. If even the marketing material is glossing over a USP, then it's a bad sign. The thought of sliding the seatpost in and out twice (4 times?) every time you end a journey is not good. I had a folding bike with a very long seatpost that moved as part of the fold. Admittedly it was 80% exposed while riding, but it got dirty and gritty very and it isn't realistic to carry a rag and assembly grease with you so it got scratched, required more force over time and became unpleasant to use. Also, this is a very solvable problem, but no seatpost means that the frame can fill with water in the rain.
