My wife said "A woman?? Cool!!"

She's so sexist.

I do not find that believable.

History of motor-paced records
Main article: Motor-paced racing

Motor pacing is a type of human-powered record where a pace vehicle is modified by adding a tail fairing to keep the wind off the cyclist who is riding behind it. This type of record was invented by Charles "Mile-a-Minute Murphy" who drafted a train to set a 96 km/h (60 mph) record at end of the 19th century. A mile of plywood sheets was attached to the railroad ties, so Charles would have a smooth surface riding behind the train.[17][18]

I saw it in a well respected dead tree publication but their
online version has a paywall so I found a link.

And why ever not? She already owned the women's record.

Yes and Murphy cheated death that day, being pulled up into
the train car at he very last second. We all grew up with
Jose Meiffret's adventures:

and of course John Howard's 1980s attempts. But this, I
think, is truly a step beyond. Hats off to her!

Interesting that #1 the front fork rake is reversed from what we're used to and #2 the front tire is off the rim after the crash. Was it the front tire coming off the rim that caused that crash?

Cheers

Right, speed record bikes have very different geometry - the
very last thing you want is snappy handling.

I don't know about the tire but tires/tubes/valves are a
real problem as we don't have 'speed rated' products for our
wheels as racing cars and motorcycles enjoy.

John Howard's Schrader valve pins depressed at some high
RPM, the solution being a classic metal valve cap with
rubber liner.

I believe it.

As I've said before, I suspect the main challenge is maintaining
control. I doubt the power output of the cyclist has to be very high,
because if the front vehicle is properly designed, there will be a
vortex of air over the top that will give the cyclist a constant tailwind.

You can see this by observing someone riding in a convertible car. Their
hair is blown forward, meaning the air hitting them has a higher speed
relative to the ground than the speed of their car.

Story in Bicycling. And video. She is 45. Rode a 7 foot long mountain bike with 17" motorcycle wheels. Tethered up to 100+ mph before starting to pedal. 488 gear inches is what she "pedaled".
