I've seen this dude riding around several times, and here he starts off just a couple blocks from Core77 HQ in NYC.
Every time I see him zip past I'm filled with questions: How does he get on and off? How does he get this thing up the stairs to wherever he lives? What does he do at crosswalks since he can't put his foot down? Who made this? Has he ever crashed it? Here we got to see the dismount at least, and it appears he just weaves while waiting for lights, but the rest is a mystery.
