now, if only someone made a modern version of the R20...

I would change...
1-1/8 fork steerer, slightly shorter head tube, 406mm wheels with plenty of clearance for fat tires and fenders, 135mm spaced rear, disc or canti bosses, 68mm BB shell and replaceable RD hanger, updated bosses for racks and fenders and kick stand mount.

but retain...
all steel, same latch, same 28.6mm seat post size and same silhouette.

When touring Tasmania on the R20, at one stage after a steam train leg, the R20 felt like a wet noodle. Very unnerving coming down the pass at Queenstown. That evening I found the hinge nut was loose. :eek: Happened when we folded the bikes to be put on the tour bus while we went on the train. Even though it is a self-locking nut, it becomes loose when swinging the frame around the hinge. But yeah, other than that, the R20 was as good as the Moulton - no flex, period. Whatever flex there was was in the luggage rack stays.

THEY do make a new R20....

If LittlePixel would chime in, he's posted links to the new R20 a while ago.

Then you'd have, almost to a tee, the steel Dahon Speed D7, apart from the disks and the Rd hanger. It is remarkable how the R20 has hung on as desirable, they turn up in my recycling centre frequently, and used to moulder there, but now are snapped up by dealers and flippers.

I am waiting on the recently announced Shimano 11 speed...then I will build up an R-20 for some heavy duty touring. I do some short trips on my current Twenty with the AG hub, does just fine, but have to stay out of the deep mountains.

well, actually, dahon frames have a very short head tube. R20 requires a 9" steerer, which has limited options. Might be nice to be able to use forks readily available on the market.

Agree with that.
On my current R20 project I'm using a solid BMX fork with V brake bosses with the R20 steerer brazed into it... MADNESS?
Yes, but it's the cheapest option for me and I couldn't find a fork with a long enough steerer.

First of all, I offered the MuP8 and Speed P8's for consideration based on experience and the fact that tomtri's style of touring appears very similar to ours. My wife and I, both 68 years old, completed the 350 mile tour described in the above link with only one mechanical problem, a flat tire. If you don't believe that link, how about the 450 mile Erie Canal, Buffalo to Albany. The only issue there was one tightening of the frame hinge.

Secondly, it would have been more helpful if your two posts were combined. Whether someone offers a positive or negative opinion, it helps to provide context. With the second post, it is easy to see that the P8's don't fit you and that they are uncomfortable for you, things Tomri needs to take into consideration, but both highly subjective aspects of a bicycle. Simply saying "no way" doesn't provide much useful information.

A further comment. We have traveled with both bikes in airline legal suitcases (62 total inches), although this did require removing the wheels. Note: I was travelling on Amtrak. I haven't flown since the airlines started charging $$$ for bikes, nor do I know how the TSA guys would treat them.

PS. I agree that riding out of an airport is the a great way to go; and we've done it in Amsterdam, Zurich, Salzburg, and Vienna.

oh, and my dahon creaks in a few spots, but I can't really solve it.

one is the saddle itself and the other is the handlebar stem clamp.
Neither of which are solvable as the bars are nitto 115, and I don't want to use flat bars.
the saddle is comfy too, so no way I'm going to switch that.
