Rolling a folded Brompton, what am I doing wrong?

[kais01]

I’ve never successfully managed it with mine so I gave up.

It’s even harder now as the single mudguard wheel had pretty much seized.

The only people I’ve seen do it easily have the luggage rack.

the single mudguard wheel is not in contact with the ground as you trolley the bike behind you, slightly lifting it att the centre of the unfolded handlebars. nor are the rear wheels of a present rack. actually its good if these latter do not roll easily, so that the bike does not roll when you sit it down. the rubber bump in the seatpost i do not use.
