Coulda hit 180 on 23 mm tires.

That's wack.

It's like being shot into the air by a huge slingshot to prove how fast you can fly.

Is the a porteur rack on the front for grocery runs?

my take as well.

That's awesome.

Shame he didn't do it on a Stayer bike, but still cool.

That's the tow bar where the bike attaches to the car so it can tow him up to a speed where he can take over pedaling. If I remember from John Howard's attempt, that was something north of 70 mph...

It would be cool, but these speeds require a double gear reduction and there's little way a normally constructed bike would be strong enough to withstand these speeds.

I think the English language 'stayer' bike is taken from the German 'Steher' which in the translation would mean 'standing' bike because the rider position is so upright. I have seen motorpaced steher races at a couple of six-day races and they were insane.

I was being facetious of course because that thing likes totally purpose-built. But the front thing looks from an angle like a rack. :D

I suspect that he was towed to a much higher speed than 70 mph. To go 174 mph for a mile on a track that is only 2 miles long requires some serious acceleration/deceleration. Oddly, the photo of the speed result printout says "Standing Start Mile", when clearly the speed was measured from a flying start.

The caption on the first photo was probably inadvertently accurate when it said, "An attachment was added to the back of the Porsche to help drag Neil Campbell along the track." In these types of speed records, the pace car fairing isn't just reducing the aero drag on the rider, the eddy currents they generate actually propel the rider forward.

Just imagine what it feels like coming out of the draft of the tow vehicle!

After reading a different article, I see that this new record is a bit different than some of the other "bicycle speed records". Traditionally, land speed records (automobile, motorcycle, etc.) take an average speed over 1 mile. But this new "record" measured average speed over 200 meters, not 1 mile.

Which is part of why the use of quotes above for "record". There are no "official" records for these types of events, because there are no sanctioning bodies and no actual rules of any kind.

Ha!
 

Wheel sucker

Oh mine is one that is totally a complaint of aesthetics, not the reality of the thing.

That's totally a purpose built machine for any human being to pedal a bike at 100+ mph.

He was fast, but not as fast as a girl: https://www.bicycling.com/news/a2328...-speed-record/

Happened to John Howard at just over 100mph -- when he had a flat. Turns out the spring in a schraeder valve will compress from centrifugal force at that speed.
