Oh, and these are folders:





Obviously they have limited luggage capacity in comparison to the full size that Bonzo posted...

Regarding the monocycle: It does not fold and has a big wheel - thus it is perfectly suited as a touring bike.

This is also a non-compromising folder,...I just haven't had the urge to tour.

In theory it sounded like a very good idea, the practice turned out to be different, at least for my taste. Weight is one thing (and a big one), drag is another (also a big one). The third was the shifting. It turned out that the XRF8w needed constant adjustment (and I mean constant!) and quite reliably often missed a gear while riding. Especially the sixth often did not make it. Furthermore it eats shifting cables for breakfast, becoming totally unreliable once it has eaten another one every couple of months. I have another XRF8w in a 20" bike that shows the same behaviour in every aspect, thus it seems not to be a single-hub-event. So from today's perspective I would not buy the hub again and can understand why Brompton did not go down that route.

I've ridden (but not owned) Bromptons that were fitted with a Shimano Nexus premium. Much, much better. Fitting is more complicated and the weight is more or less in the same ballpark. But it has less drag and shifting works totally reliably.
If you still want the S/A 8-speed in your Brompton: There is a kit from Ben Cooper/Kinetics or you can buy the Hub from i.e. SJS and do the rest yourself.
It is funny, I have used both a Nexus 8 and a Sturmey Archer X-RF8w and agree with you. I remember adjusting the Nexus 8
once over 4 or 5 years. The X-RF8, I've just put in my 2nd cable in 6 months. Now granted a cable is cheap and easy to install. The friction and noise of the X-RF8 still bothers me but both have reduced a bit since I've racked up over 5000 kms on it.

Apropos IGH...

i am in the midst of building my Bali Bambu 26er. The frame has horizontal dropouts so I got to thinking about lacing up a wheel with an IGH. Problem is i font know which IGH meets my requirements:
1. Not insanely heavy
2. Not insanely expensive
3. Range of at least a 11-36 cogset
4. Smooth shifting
5. Efficient, not draggy or friction prone
6. relatively Maintainance free
7. takes disk rotors
8. black color
does such a thing exist?

You must have seen my Shimano Nexus 8 (SG-8R30) vs Sturmey Archer 8 (x-rf8w) vs SRAM i-Motion 3 post last year
SRAM pulls the plug on IGHs

The Nexus was my clear favorite and I think it meets all of your conditions above, except that model I had weighed 2 kg.

I have a Sturmey Archer S-RF5 (w) on my Crius. It isn't made anymore but you can still source them. I haven't put enough km's on it to recommend it or not. Quiet and low friction. Perhaps the shifting isn't the smoothest. There are newer models, but I don't have any experience with them.

Thanks...

My LBS has the Alfine 8 at 1,680 grams (claimed). I am thinking this laced up with Surly Rabbit Hole rims...
