Ok, it was a long time between updates because my bike order kept getting delayed. I finally have it.
Overall, I really like it. However, three things disappointed me in Dahon as a company.
1. According to the specs page, the 2010 Jack D7 comes with "Suntour folding, non-slip" pedals. This was not the case and when the guy at the store called Dahon, they told him this will never be the case.
2. According to the specs page, the 2010 Jack D7 comes with the "Dahon Axis, patented InfiniteAdjust technology" stem. This was also not the case, it came with the same stem as the 2009 model. On the same phone call, we were told that they don't have the Axis stem yet so they are shipping the 2010 models with the 2009 stem. They did not know when bikes with the new, advertised stem would be shipping and would not be doing anything for people who get bikes with the old stem.
3. When told that maybe they ought to change the specs on the web page, they said "we can't do anything about that, that's Dahon Global and we are Dahon USA."
Those things really rubbed me the wrong way. But I needed a bike now and the test drive was great. The store where I purchased the bike is actually going out of its way to accommodate me by ordering folding pedals for me and just swapping for mine and will also do the same when the Dahon Axis stem comes out, which they totally didn't have to do since it's not their fault that Dahon's web page is deceptive.
There were heavy thunderstorms here today so I have not taken a real ride on it yet, but I did install front and rear lights and took a couple of short test drives and despite not having features I thought it would have, I am otherwise very pleased with the ride and portability of the Jack D7.
