This is just amazing. A groundbreaking feat of design and engineering.
Maybe I'm just in a bad mood today but I found this really annoying. Maybe I should redirect my negative energy into something positive like taking a 16" wheeled unicycle, adding folding pedals and then marketing it as the ultimate in lightweight compact urban transport. It's easy to store, small, light, doesn't have a dirty drive train and is easily transported through turnstiles and onto public transportation. I'd like to see how many people applaud that.
