83 mph at infinite mpg
 
... over 0.6 miles, that is.

Dutch cyclist Sebastiaan Bowier breaks world cycling record in Nevada with speed of 133.78 km/hr (83.1 mph) : mpoppel
http://cdn.c.photoshelter.com/img-ge...-challenge.jpg
Here is a vid: http://www.youtube.com/watch?v=LY6FEzJSLng
It is in Dutch, but I'll translate:
"How did it go?"
"oh, it went nice, yeah."
"Nice wind, eh?"
"We can go surfing."
(clims from bike)
"What does it say?"
"135" (km/h). Everyone cheers.
"At a given moment I did no longer tell him the speed. He managed it on this own, and this is what came öut of it"
Sebastiaan explains how he built up the speed before the timed area. When asked again he says he was pedaling lightly in the beginning, and full out in the end.
Another (professional & time-track specialist) rider just did not match it, complains about sidewind.

Wonder what the angle of view is on the bike camera...

Certainly an impressive feat!

I take it on that long level straightaway at Battle Mountain just off I-80?

"Battle Mountain, Voted the Armpit of America by the Washington Post. Make Us Your Pit Stop!"

Grant-53 08-16-2014 12:42 AM

See recumbent.com for details. Nobody asked about my vote for the armpit of America;)

Actually there is a miles per gallon associated with bicycles, but it's the mpg of water the rider drinks to stay hydrated and can vary from 25 to 50 mpg depending on the amount of heat, humidity, and the cyclist's power output.

I like to call it a "miles per ham sandwich" rating, which is unfair to our Hebrew friends but "miles per airline kosher meal" doesn't have the right kind of rhythm.

So... most of us get better mileage in our cars than cycling! Too bad I only have my bike right now!

It kind of sounds like the HHO scams that just claim you can use water for fuel and then lose you in details that defy logic.

Miles per turkey sandwich? :) Honestly, I think that is a better measurement, although you could have a small one with cheap ingredients while I made a party sub, but why get technical like MPPoTS, Miles per pound of turkey sandwich? :)

Cyclists do not use the water for energy, but instead for their cooling system.

RedDevil 08-18-2014 10:50 AM

Miles per gallon even applies to walking, if I may rethread: http://ecomodder.com/forum/showthrea...tml#post363102
:p

RedDevil, I didn't click on the thread - I will but I'm at work and a bit time constrained - but the title gets me: "What's driving the average human?"

For women: chocolate.
For men: women.

Sexist, yes, but that's my knee-jerk response, just going for the cheap laugh at the moment.

See the chapter on Nutrition by Asher E. Jeukendrup in the book "High-Tech Cycling" edited by Edmund R. Burke. Water consumption is typically one liter per hour so 25 miles per gallon would be extreme conditions. It can get very warm sealed in a HPV fairing.

I could have sworn that for cyclists it went by MPB(burrito), at which case I am nearing 73 miles currently. With a rig like that, a wide enough variation on gear ratios, and no headwind I don't doubt that I can beat 100mpb.

Grant-53 09-01-2014 08:42 PM

How many grams of carbohydrates and fat on the burrito? Is it an Imperial or US burrito? Did you weigh yourself before and after? Inquiring minds want to know;)

True so that means you could compare humans to steam engines for the water used? Any thoughts?

Interesting, but I imagine that coal contains more carbon than human food.

Grant-53 11-25-2014 03:50 PM

I will ask my favorite sport nutritionist, Joe Pastabelli;) Actually there are any number of books and sources on food as fuel for humans. See "High Tech Cycling 2nd Ed." edited by Edmund R. Burke. Chapter 9 on nutrition was written by Asker E. Jeukendrup with a bibliography of 27 entries. Of course all bio-fuel is produced by plants removing carbon dioxide from the atmosphere.

Came across this discussion and the numerous comments. I don't expect to ride a velomobile at highway speeds at my age but many of the trips within a 25 mile radius are suitable for bike riding. The big gains in aerodynamics are what I am after with the additional benefit of protection from the elements.

I'm surprised that you are not trying to work with a recumbent bike. Although they are a lot more expensive to find around.

RedDevil 11-27-2014 07:38 AM

+1 on the recumbent bike...

There are pros and cons in the selection of a recumbent or an upright. I would not discourage anyone from trying a recumbent. I have ridden the Linear LWB made by The Bicycleman, Pete Stoll. A LWB recumbent does not fit down my cellar stairs, may weigh more, may not fit on the bus rack, and I like the height of an upright in traffic. My target market is low income commuters on mountain/hybrid bikes and a goal of reducing drag by 25%. Many of the lessons learned apply to scooters and light motorcycles.

A 4 person pedal car with electric assist based on a low drag body such as the Mercedes-Benz C-111 Mk. 3 would interest me some day as a project.

For those who want to see a real street ready streamliner check out the Peregrine on Birk.
