That's a novel design! Folds up nice and compact, and has a big wheel so cracks in the pavement don't murder you. I've seen a few similar things that looked pretty damn ridiculous (like
this stupid thing. The highlight is at 2m11s when they describe it as 'built from recyclable aluminium, the same way Apple laptops are made' which says it all. I must've laughed for a whole minute at that).
Still not sure about the handlebar placement though. The nice thing about bike handlebars is that they support your weight so you're not constantly working to keep yourself upright and balanced.
One problem with this kind of thing in the UK though is that electric vehicles are
pretty limited by law. Even the famous Segways are illegal!
