Notice no helmets on anybody. They don't have to worry about roads designed for high speed car traffic and the entitled drivers careening potentially out of control upon them.
More failings of modern American transportation planning.
Oh, and this comment from the youtube page deserves its own special recognition:
I wish US cities looked like that, but our fat asses would swallow the seats. Maybe if the bikes had cheese cake dangling in front of them like carrot on a stick. Hm, this is making me hungry I think I'll drive my SUV over to McDonald's and get a tub of lard to eat in the park. Oh wait... my city doesn't have any parks. We turned them all into parking lots for the McDonald's.
