What the heck is this bike and where do I get one?
This bike solves the problem of visibility among dense traffic while riding a recumbent (actually a semi-recumbent) bike: https://www.youtube.com/watch?v=GEhLYKJA9pQ. What do you call this thing? Is it probably a home-made one-of-a-kind, or is someone making these for sale? (If you can't watch the video, here's a clue: this guy is riding along a busy city street in congested traffic on a crank-forward-style bike. You can barely see the top of his head at first, and he surely can't see much of the traffic ahead, so he does something to the bike and suddenly he's riding a tall bike. Then when he gets a good view he decides not to continue that direction of travel, maneuvers among the cars, makes a U-turn, and whoop he's back down as a semi-recumbent again, then zip he's up to a tall bike again.)
