I do like using the seatpost, but when I do that:
- The bike doesn't stay locked together. You have to push the post back down to grab and carry it.
- with the standard size wheels, I have a limited range of how much I can tilt before the elastomer drags. Larger wheels (90mm, 100mm) make rolling and tilting easier, but the standard 2 wheel rackless bike becomes wobbly when just sitting in its folded state. I suspect a rack (which gives a more stable base when folded) would benefit from larger wheels, and would also roll quite nicely. I finally settled on some skate wheels that are nearly identical to stock diameter and drag it behind me. Not nearly as nice as my strida, but waaaay better than carrying.
