I rode a Dynamic shaft drive
I rode the Dynamic Sidekick 7 speed shaft drive folder for about 3 weeks. I bought it with a 30 day trial offer. The people at Dynamic are very good to deal with.
I really liked having an internal gear hub, and being totally chain free by having a shaft drive was wonderful.
So, why did I send it back? Mainly, it did not fit my long legs, without going beyond the seatpost min mark. I did not want to do that long term. The new model will have a one inch longer seattube, and so it should fit me, 6ft tall with long legs. I could have added a ButtBuddy to gain 2 inches, but I did not want to invest that in the 7 speed bike. I would only own one with the Nexus 8 speed hub. I needed a lot more low range, without giving up on the high range. The Nexus 8 speed will do that for me, (307% range instead of 244%). They did not have the 8 speed available at the time, and I did not know that the 7 speed would not work that well for me until I tried it.
The bike also did not fold well, did not stay folded, and rarely stood up by itself. I used it as a "lay flat" by only folding the handlebar post, lowering the seat, and rolling it into the backseat of my car. If I get a new one when they become available in Oct, I might cut out the frame hinge, and weld the frame to make it a layflat. The folding is as bad as a cheap folder, nothing like a Bromptom or Dahon. Dynamic wanted to have Dahon make frames for them, but Dahon was not interested. Dynamic was receptive to my idea that they add a lighter layflat to their line. This bike was very heavy, 32 pounds.
I may buy the Crosstown 8 instead from Dynamic. It is a full size, non folding road bike, but it is only 27 pounds, and has a wide gear inch range since it has 700C wheels. I would opt for the lower range drive, but you can read their gear inches and decide for yourself. If I add folding pedals, and remove the front wheel, I could fit it in my backseat as a layflat. I drive a very small 1991 Civic SI hatchback that I bought new and really like.
I would definitely recommend a Dynamic bike to anyone who wanted a very clean and low maintianance bike. If you get the Sidekick, I would recommend upgrading to the 8 speed. You would have a bike that rode and maneuvered well with its 20" wheels, and can work well as a layflat, but remember it does not fold well.
I'm a sucker for shaft drive, having had a broken motorcycle drive chain crack my crankcase on my Suzuki SV650, I've only ever had shafties since.
It seems like a natural for bikes that aren't all about weight.
Damn, I wish I had known about this bike before buying my Dahon. It even has the springy saddle...
A couple other things: Dynamic's site says that it's only good for people with up to 34" inseams. Is this wrong or was it not there when you were researching?
I have a '98 Civic hatchback, which is just starting to rust out on me now. (162k, 9 Chicago winters) Before that, I had an '85 CRX, (193k, 14 Chicago winters) which I also really liked.
The new Si's have no torque at all, and don't feel very quick, especially for the money. We wound up going with a Matrix. Would've gotten the Yaris, but the wife didn't like it and it wasn't quite big enough for when we have kids.

Also: What's the deal with changing flat tires on the rear wheel? Does the wheel come off and re-mount easily?

On the next new bike I get, I will be putting airfree foamfilled tires on, so I will only be messing with the wheels once. I have been using airfree tires for about 35 years now on my 700C wheels. I like things clean, simple, and maintanance free.
