Andy Well, if you're going to accept using a dragster to counteract aerodynamic drag for you, what's a little tow up to 100 mph. Just think of it as a "sticky bottle". |

Without the dragster in front would one be able to stay on the bicycle at 183 MPH? My "Science of Cycling" app says that in still air it would require some 72020 watts of power to ride at 183 mph without the dragster, or about 1032 calories per minute :-) -- Cheers John B. |

That's only 100 hp. Take your ACME leg vitamins and start training. https://youtu.be/kM-91sthsaE |

Andy My point is that at those speeds tires overheat and throw the entire rubber tread off. So it requires specially built high speed tires that are like racing tires and have a tread that weighs nearly nothing so that there's no centrifugal weight effect enough to peel it off. And I believe that she had to be towed up closer to 150 mph to be able to turn that gear over with enough force to remain in the slip stream. |
