I used to have a toy car with a fly wheel in it that I could send all the way down the hallway - the ones with plastic wheels never made it halfway. That’s about as far as I get.
Something like this, maybe???

The flywheel is a myth in that it helps (obviously flywheels exist). The heavier the wheel the more energy it takes to get up to speed and this is always more than it conserves by spinning down slower. This is why we didn’t solve the energy crisis years ago by every house having a generator powered flywheel powering a generator to light our houses ;-).

Nobody is claiming that it is perpetual motion.
How do the arguements posted so far differ?

that the inertia helps you get through the “dead spots” or weak spots of your stroke more easily and there is no penalty for the extra weight once you spin up to speed on a flat straight course.
Obviously the heavier wheel doesnt make it spin longer than the energy put into it. But the heavier wheel will be “more resistant” to drag, and require less energy to maintain spinning once its going. I havent done the math and shouldnt at work, but Ill bet its a couple percent saved in power output over reaching and maintaining a constant speed.
So I should get a 100 pound wheel set if it is a flat course? Actually, why stop there? I will generously beat the previous offer of .05/dollar and offer .10/dollar for your obsolete lightweight discs. I will accept shipments from overseas as well.
You are all missing the obvious point, he went faster because he believed that it would make him faster! It all comes down to the engine, I doubt that heavy wheel made much difference on the velodrome either way. The hour record is all about pain tolerance, and if you believe that a particular feature of your bike is going to help then it will make you ride through the pain.
maybe the 3,2kg has something to do with stiffnes of the wheel - as far as I know you can’t use disc wheel - but it has to be min 16 spokes in each wheel… and max 25mm high rim - if they go for best aerodynamik they need a very strong / heavy rim… it’s a pretty big guy (200cm / 90kg) !
And I think it is a typo - the 3.2kg must be for the wheelSET… but could be nice to see his bike !
Get a 100 pound wheel up to the same speed as a 2 pound wheel. Then let go and let them spin. Ill bet anything the 100 pound wheel spins longer.
Thats all Im saying here, and thats whats going on on the hour record - you get up to speed and hold it as long as possible. And while it takes longer to get a heavier wheel up to speed, you can hold a higher speed easier.
I can definitely agree about the mental thing.
I would agree that the inertia may help you get through dead spots. But, if you just keep doing that, then the wheel speed would continue to decrease. Thus, if you expect to be making energy withdrawals from the wheel, then you have to make equal energy deposits at a different point in the pedal stroke by pushing harder, and that will be harder with a heavier wheel than a light wheel. So, there is your “penalty” for the heavier wheel.

You almost feel sorry for Boardman loosing it…
"In a bizarre twist to the event, it later emerged that up until two hours before his ride, Boardman had believed that whatever mark he set would be regarded as the new record.
When officials informed him otherwise and that he would actually have to beat Merckx’s mark, Boardman was suddenly faced with a tougher task than he had anticipated.
With only minutes of the hour remaining, he was 0.1kph/0.006mph off the pace but a partisan home crowd roared him on. Boardman called the end “the hardest three laps of my life” but sneaked an improvement of 10m/32.81ft over Merckx’s 1972 record.
After the finish, Boardman was close to collapsing and had to be helped off his bike before remarking: “I’ve never been in so much pain after a race.”

Seeing I stilll worship Boardman I think he needs to pull the lotus out of the attic do some upgrades and destroy the hour record. Is he too old, no because I am a fan and will not think he can age. The athletic hour is a stupid joke and technology needs to be accepted back in the hour record, because it already is.
Flywheel or not…inertia or not…lightest wheels or not…he set the record. If he was on a Schwinn Stingray with iron discs as wheels it would not matter…he set a new record. Amazing!!!

No, what is amazing is if he had followed the advice of the many slower riders here and used different equipement he would have broken the record by a lot more.
Hey it was an incredible ride but I see it as a wasted effort. The hour record is the farthest distance covered in an hour. I can’t understand the need to not allow legal race euipment just for the worship of Eddie.
If he would have followed this slow riders advice he would have done it faster.

I believe Sam Wittingham went over 52 miles in an hour last year in an HPV. I mean there has to be rules for these records to mean anything if we are going to compare athletes. Allowing “legal race equipment” says nothing about the athlete. This does.
The fly wheel effect is a myth and I am tired of this so called athletic record. Eddy used the top technology of the day and the race is about speed.
With the UCI’s hang up on “athletic” shit we should just strap everyone to a bike in the lab and let the numbers win.
Speed? Who cares?
Once again your stupendous understanding of the physical universe underwhelms us Tubbs. TriBear is right in his response to your post. And what is this drivel about Merckx? Do you have any idea what point you are trying to make, other than recycling what others have posted?
Dude get a life. I mean my god what is your deal. I can tell you where my house is and you can come make out with me.
The fly wheel doesn’t work because there is no free energy. The second power is stopped being put into a wheel is slows. I have never seen a track race of anysort where people coast to take a brakey poo. Yes sprinters track stand but that is to force the other dude to lead out.
The energy needed to spin that heavy around the track could be better used else where.
" Do you have any idea what point you are trying to make, other than recycling what others have posted?"
Yes my point is that this is an evolvling sport that this need to hold on too a tech point from the 70s, one which is not deing held too because Boardmans helmet and clipless pedals where an advantage Eddie didn’t use, is backward and pure idol worship.
As far as copying people I am the only one who defends this point and we have been arguing this long before you came around.
