A folding bike section - nice!
I have a Bike Friday Pocket Nomad which I converted to a 56" gear single speed via Singulator (otherwise it won't fold), and just recently purchased a Brompton L6 which has basically turned into an L4 - I somehow lost the ability to switch into 2nd low or high gear for some reason. No matter though: I'm a fan of single speed anyway.
Here's some
pics of the BF.
