I had a DS when they were first available in 2008.. I did not like the gearing .. 80 g/i is way too high on 8" wheels .. the 165% overdrive is a lot.. the Sachs/SRAM/Sturmey 2 speed hubs are at about 136% .. .. a single speed would probably be fine for the OPs intended purpose (other than the 34" seat height at minimum insertion - this bike is not designed for tall riders) .. but if you are trying to dual purpose a folding bike to be something besides a .3mi shuttle vehicle, I'd still look hard at a Dahon Curve D3 ..
