Birdy 2nd Generation Monocoque
Hi Everyone!
I’m hoping someone can help me. I cannot, for the life of me, figure out how to fold and unfold this bike. This is the 2nd generation. The back wheel seems to be stuck somehow. Please help!

Is the seatpost sufficiently extended ? The inserted seatpost lock the rear wheel folded (or unfolded) like on a Brompton.
To fully fold the rear wheel, the chain must be placed on the smallest sprocket.

The seat post appears to have a blocker that does not allow it to reach the ground when folded. However, that is not what is preventing the back wheel to unfold.

The seatpost should go to the ground.
If it cannot, its the blocker is blocker you mention which isn't well adjusted (its adjustable with a nut on a threaded bar), this piece is used to lock the rear triangle when folded. The picture below is a Birdy 3, but its the same on the Birdy 2.

The knob circled in red is designed to press against the seat post when the post is all the way in. It keeps the rear triangle from moving when the bike is folded. Screw it in further and the seat post should slip past and will touch the ground when it's all the way in. If you can't screw it in any further, the most likely culprit is the rear tire touching the frame and preventing the rear from being folded as far as it should be. The tire looks over sized to my eyes.

There is another reason for not being able to completely fold the rear wheel and not being able to push completely the seatpost: its the chain not being on the smallest sprocket !
To be able to fully fold the rear wheel, the chain must be placed on the smallest sprocket.
