Recumbent Bikes!!!
 

I'm big on biking places. I rode my bike everywhere all through college, including to parties and a couple times to the bar. I currently have two bikes, one is a all mountain rig with 6 inches of travel all around, and the other is my beater put together from spare parts. I was looking at getting a road bike since it's been unsually rainy and the trails are all muddied up, which can be awesome until the trail police catch you when the trails are closed. Then I started looking into recumbent bikes. These things are still bicycles but you sit in a reclined position and pedal with a couple different muscles compared to a normal bike. I thought they were interesting, but who would want to ride in one of those. Then I say that the world land speed record by a human powered vehicle was a recumbant doing 80mph. Researching this a little more it turns out that these things can be made very aerodynamic with the use of fairings. I just have this image in my head of people traveling down the highway doing 80 on a bike.

Recubents seem like they would be good for long trips. They have the aero advantage like you mentioned. But I think a traditional bike would be better in the city and on hills.

I used to race MTB until my body gave out. Now I ride and bootleg race a road bike. Commuting to the store and errands is great they are quite a bit faster than a MTB. Maintenance on a road bike is a little less involved also. The folks I know that ride the recumbent say it good on their backs. The only thing about a recumbent is that being low to the groung there kind of hard to see unless you put a flag on it. And 80 MPH is for a short distance only but it would be cool to go that fast on a bike. I've seen 50 mph on a downhill before and even with sunglasses the eyes still water pretty good.

Street Luge?!?
 

I see a new X-games sport. Extreme recumbents!!!

not quite on topic, but damn:

I saw that video before. I think he was using a different frame (a carbon fiber one) on the second run.

Stress Fracture
 

Carbon fiber on that kind of terrain is just asking to wreck at those speeds. He probably would have been better off with a full suspension downhill rig and some body armour

As far as I am aware, the Varna-II averaged > 80mph for an hour. I don't think that's a particularly small distance, but hey.
