Interesting bike...seems to be a combination of my Brompton and Swift in the rear wheel folds under the top tube, (both) and the seat post and stem riser come out with a QR (swift). In fact, my Brompton S only weighed a few pounds more in a single speed configuration and Jur's Swift weighed a bit less than 20 lbs, if I recall. Also this bike seems really stripped... no fenders, no lights or reflectors and is a single speed. I couldn't tell if it had a belt or a chain. Not revolutionary, but a well thought out and attractive package. Should have minimal maintenance needs as well.
