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]

But that's cheating to draft behind a car. :wink: A flat tire could be bad. Do they make Z rated bicycle tires?

That chain ring setup looks like something some of us could use on the faster ebikes.

Thats what I was thinking too, that gearing is crazy.

Maybe she uses narrow motorcycle tires, or perhaps custom made.

I bet tough road bike tires handle the speed fine for at least a few miles.

Kudos to her, that's a totally reasonable pace to achieve on a pedal bike.
