I know this is a social issue :rolleyes:, but it’s worth posting because it’s a pretty amazing feat.

Slowing down and leaving the bubble must have been darned scary.

I have always been a fan of bicycles, thanks for sharing. Them new electric bicycles these days are great.

There is nothing amazing about being towed by some type of vehicle to get to a given speed. I doubt anyone ever attempting it before because it means nothing.

[doublepost=1548027310][/doublepost]Sorry, but I would not even consider going that fast on a bike. Any idea what you would look like if you biffed it?

Perfect! As an engineer could you comment at all about the science behind this? Since a rider is within a air bubble what is happening? Are they being pulled along? What pace do they need to pedal to maintain drafting?

Whaaaaaa…? That is exactly how these records are set. It's called motor-pacing and is used to mitigate air resistance and get the bike going fast enough that it's physically possible to pedal it. As for nobody ever attempting it before, motor-pacing was first conceived of in 1899.

The previous motor-paced record was set in 1995 by Fred Rompelberg and was over 15mph less.

She was only towed to get up to speed, around the 57 second mark you can see the tow strap let go and then she is pedaling on her own keeping pace with the rail car, she actually appears to gain on it a couple times.

What gear is she in, 35,175th?
Appears to be fixed gear with a double multiplier. You could probably stand on one pedal with the bike standing still and it wouldn't go anywhere.

I believe she dropped the tether at 157mph and she was able to keep up with the accelerating lead car from that point, while in her drafting bubble.
