Hi origamiists! I have a couple of Raleigh Twenty folders, both alloy customized to around 25 pounds. One with 406 mm wheels and a Sturmey-Archer S5 the other with 451 mm wheels and a fixed gear. The 5 speed is my travel bike, and I have climbed Pikes Peak on it. All this is slightly relevant bragging prior to my main question. I am retiring, moving to New York City to be close to both my kids and my grandkid, requiring downsizing to a 2-bedroom apartment. I have 3 other full size bikes, but life in a small apartment would be more comfortable with only the folders. Life in retirement would also be much more enjoyable with regular long bike rides exploring NYC and the surrounding country. So (finally) my question is: with the small wheels and fit compromises of a folder, what is the the longest continuous ride people have I done on a folder? I am especially iterested in non-suspension folder experiences, as I love the ride of the Twenties. I just have never ridden them for more than 5 hours straight.
