174mph On A Bike

Postby richardfm » 18 Aug 2019, 7:55pm

Rather him than me, but isn't getting a tow cheating?

Of course getting a tow is cheating, this is not cycling :?

Would it be possible to accelerate to such speeds behind a car-borne wind shield but without a tow, from a standing start?
It seems unlikely to me, and even if possible it would surely take a considerable distance.
The gearing would be interesting.
Racing behind a motor vehicle like a Derny and in the Bordeaux-Paris has been long accepted.
I am not trying to excuse the cheating, but cheating perhaps requires intent to deceive. There was no such intent here.
Whether or not it was cycling rather depends on how you want to define cycling.
It was certainly an interesting, brave and athletic enterprise.

That's 10 mph less than the record of 184 mph set by this lady on the Bonnerville Salt flats in Utah in 2018.

At the last count:- Focus Variado, Peugeot 531 pro, Dawes Discovery Tandem, Dawes Kingpin, Raleigh 20, Falcon K2 MTB dropped bar tourer, Longstaff trike conversion on a Falcon corsa. :D

Yes and with her it says she was towed up to just 50 mph then released so she built up the other 134 mph by her own efforts all be it helped by the slipstream of the vehicle.

I imagine the gear needed to pedal at 184 mph would be so big that it would be impossible to get it turning from a stop.

It also says she was timed over a mile not just 200 metres like Neil Campbell.

For me it would simply be a matter of reaching 90rpm in top gear* (about 20mph) and then winding it up to 847rpm :wink: .

*By the standards of many my tourer is under-geared.

I read that he was released from the tow as he passed the gate, presumably at 174 mph. This is very different from accelerating from a 50 mph release.

edited to correct speed.

I guess the lady in AMerica wa stowed up to 50mph because that was the minimum speed for her to pedal the huge gear.

Same as if me and my bike were chucked out of an aircraft at 20,000ft.

The ground level method does take longer to stop.

The airlines can probably accommodate you. I've seen a couple of Facebook pleas from folk who've flown to PBP: "Anyone got a spare bike? Airline b0rked mine". And one simply lost.
Have we got time for another cuppa?

She was towed to something over 100 mph before release.

Ps. Lithobraking is not recommended as it can be hard on the body.

Luck ....... :D

It says 110 mph in the video , the article says 50.
Still doesn't take anything away from her compared to the other attempt. She still built up another 74 mph by her own efforts and held 184 through a measured mile. The other guy was measured over just 200 metres and was 10 mph slower.
