I have a syntace stem on mine, with a cool carbon handlebar ....with bar ends....

I can fold the handlebar just fine.
And yes it rolls really nice with the seatpost stickin out.
The smaller bags I hve from Klickfix will allow to stay attached when folded .... the bigger wicker basket has to go off the bike however.

more mods to come.. when I have time I will make a page with all the details
