Hi Since birdy-freunde is gone this seems to be the best place for birdy-related info and I´d like to contribute.
After much deliberation I bought a R&M Birdy Rohloff with 10 degree "comfort stem" a few months ago. It has since been my "daily driver" during my work week and I want to tell you about it.



A few things are modded:
- Hard Elastomers front & rear
- Saddle, bell, smartphone mount
- 80mm Wheels from old inline skates
- 8l cooling bag on the rear rack, containing a very small folded backpack and either rain clothes, cold drinks and a cooling pack or hot food, depending on the occasion (permanently attached)
- R&M "Carry Bag" on the top tube, containing a multi tool, small lock and puncture sealing kit (permanently attached)
- Mini pump with integrated pressure gauge under the rear rack (permanently attached)
- H&H Brompton bag adapter for Birdy
- Brompton luggage block
- Canoo handle to pull the bike while folded (attached to H&H adapter)
- 23l Brompton "Metro Messenger Bag L"

The most important reason for these mods was usability. All I need for 5 days has to fit on the bike, I travel by train a lot and do not like to carry a backpack while on the bike.




Everything but the Brompton bag can stay on the bike while folded.
The bike is still small enough to fit inside the Carry Bag cover. This is important for taking the bike inside "unfriendly" places (which has happened to me 3 times so far).




This is the canoo pulling handle, bought for ~10 € on Amazon. It allows to comfortably pull or push the bike while folded, does not rattle and never needs explicit handling. It simply stays out of the way until needed.
When carrying the folded bike up or down stairs it doubles as a carrying handle (the other hand gripping the frame).
Of all mods it is my favourite.




Pulling or pushing the bike while gripping the canoo handle is nearly effortless. The larger (compared to 50mm R&M standard) skate wheels make the cooling bag not touch the ground.




There is ample space between bag and stem. I would not expect this to work with the 21 degree "sport stem", however.

I am _very_ satisfied with the bike in this form!
The combination of driving characteristics even when fully loaded, ability to take a _lot_ of luggage (~10kg in the Brompton bag), quick foldability and ease of handling when folded make me quite happy
While I do not find my Birdy to be very beautiful per se it epitomises "form follows function" imho.
