I can provide some input on the Speed Pro TT. I have had mine for ~8 months now and LOVE it. With all my stuff on it (lights, water bottle, pedals, tools, etc) it weighs in around 23 pounds. But I'm 5 feet tall and about 125 pounds and I can carry it with relative ease. The smaller 20" wheels did take some time getting used to. At first, they felt a little squirrely. But I quickly got used to them and, for riding in city traffic, find that they are preferrable because they are easier to manage around cars, people, and anything else I encounter. I can reach some pretty decent speeds on this little bike. In fact, I go about as fast on it (max 25 mph) as I do on my high-end Trek road bike.
It is very fast and nimble and, for me, incredibly comfortable to ride. I would suspect that anyone over 5'11" tall would not be comfortable on this bike, but the bike boasts some highly-adjustable features, which should allow it to accomodate a wide range of cyclists. The frame is surprisingly shock-absorbing when riding through city streets. The roads here in DC aren't in the best condition, but this bike takes them well.
The speed pro TT does not fold down as small as some of the other bikes, but I can easily take it on the Metro with no problem (taking it on the commuter train is a bit more difficult, but I do that too when necessary). The reason is the track-style handle bars. If you need a smaller fold you can take a wrench and fold them down, but that would add time and probably isn't necesarry in most circumstances.
As for maintenance - ALL folders are a bit more tempremental than your average bike. This is because they are moved around more, have more moving parts, and have some unique features. Regarding the speed pro TT here are some of the things I've had issues with.
First, like all folders, the cables are longer (because you have to fold everything up) and this can present some problems with delayed braking and cables needing to be replaced more often. I replaced the stock pads with some Kool Stop Salmon pads and noticed a marked improvement in braking capability. I also clean the bike every few days and give it all the tender love and care it could desire.
Second, the hub gear on the speed pro can be a little tempremental. I'm having an issue with mine currently that, while it hasn't made the bike unrideable, has been annoying. This happens. To solve this issue, I made sure I bought my bike through a local dealer that does free tune-ups (which I would highly recommend if you can get away with it for any folder, unless, of course, you're more bike-saavy than I am).
Third, with any folder, because there are moving parts, you have to give the bike a close, visual inspection each time you get on it to ensure everything is secured. So far, my Speed Pro TT's folding and locking mechanisms have all withstood my daily folding and unfolding.
Fourth, when in the folded position, the magnet that holds the bike together can sometimes come undone. This has not been a deal-breaker for me- I just tie a bungee cord around the two sides and it works just fine. Even with the bungee cord trick, folding time is still less than 30 seconds and very easy.
Overall, I LOVE this bike and would buy one again in a heartbeat. For me, it has been worth every penny. When I realized I needed a folder for my commute, I wanted one that handled with the speed and agility of a road bike, but was easy to fold up and carry onto the Metro. In that respect, the Speed Pro TT delivers 120% and then some. I ride upwards of 20-30 miles on each day. My longest daily mileage on it was a little over 60 miles. It is incredibly comfortable and has quickly become my favorite bike. I think there are a few improvements Dahon could make, but FEW is the key word here.
