I was lucky enough to be in Copenhagen when Larry Vs Harry (makers of the Bullitt) had organised a cargo bike speed record attempt at a airstrip outside the city. Rather than pay for someone to come and officiate so it was a ratified record, they spent the money on beer instead; transported by Bullitt, of course. http://www.larryvsharry.com/world-record/
What sort of power do you need to be holding to do this. Once you have a vehicle punching a massive hole in the air, what are we talking about?
I hope they will make the power profile available from the Infocrank.cc that she used for training and the record. I guess the Infocrank is the fastest power meter in the world now.
Interesting question.
There’s a graph on this page at Wikipedia:
https://en.m.wikipedia.org/wiki/Bicycle_performance
showing the power needed to overcome various forces at various speeds. If you disregard gravity (this was done on the flat) and accceleration (you’re asking about the power needed to hold that speed) and air resistance (that’s what the lead car is for) then you only have rolling resistance to worry about. The graph has this scaling linearly up to 50W at 10m/s. If we assume it continues to scale linearly up to 83m/s (184mph) then you’d need to be putting out 415W, which is not that astronomical. Probably less for her, actually, as that graph appears to refer to a 95kg rider or possibly rider plus bike. Either way.
Jeez, now that's impressive. I mean it's really, really impressive. I really like her choice of pace vehicle. You've got to be a bt of a nutcase to try something as utterly bonkers as riding a bicycle that fast. She's a star.
I've always meant to go to Bonneville but had to turn down the offer of a trip there to see JCB win the record for a diesel powered vehicle some years back alas. I had a prior engagement.
There seem to be lots of bicycle speed records:
https://en.wikipedia.org/wiki/List_of_cycling_records#Speed_record_on_a_bicycle
- but I couldn't see one that's one on the flat, on a normal bicycle-shaped bicycle without motor-pacing. 138mph "downhill on snow" sounds good though!
I like this one "Pedaling on a bicycle treadmill (rollers) after being "towed" to 100 mph, on a custom made £1,000,000 bicycle".
Barriers to entry look quite high...
I too would be interested to know if there are actually 'proper' records, such as fastest unassisted speed on flat ground, indoor/outdoor over various shorter distances?
It must be shit scary riding ar those speeds. Its more of a drafting event, just need a faster vehicle for 200mph record
Not sure it's quite that simple
Sweet ride, there's a video on FB of the radio transmission and the direct aftermath. https://www.facebook.com/FireCycle/videos/262786141039440/?type=3
Apparently they were not supposed to let the drag car go over 175mph ... oopsy
