Hi Nish, thanks for sharing your experiences with bagging. I used to work in a bike-hostile building, where the only way I was going to get my bike in the door was by bagging it. This was with another bike, but I remember it being a small pain to bag and very awkward to carry bagged, so I would only bag at the last minute. Since then I've worked for more bike-friendly offices with indoor bike-parking facilities. When I'm commuting other places, if I can't bring my bike indoors (e.g., movie theater), I just lock outside and remove the seatpost. So, yeah, I guess I don't really need a bag at this point.

You've confirmed my finding with folders overall, that the folding generally makes the bike compact but more difficult and awkward to transport. It's much easier for me to carry the bike unfolded when climbing stairs and roll it unfolded on sidewalks, ramps, and platforms. So I reserve folding for storage/baggage purposes only.
