The last time I bought a new bicycle, I had to try a lot of them before I found one I really enjoyed. I'd imagine world-class cyclists are even pickier than I am.

Yeah, it'd be like telling marathoners they have to wear a specific model of shoe. There's so many factors that go into comfort etc.

Except that the team get sponsored by a manufacturer, and it's not picked by the riders.

Just take the bike out of the race entirely. Declare a year in advance that the bike will be XYZ model Q so people can train on them, and the race maintains custody of all race bikes, spares, etc. It's already a money-competition to see who can buy the best super-bike. Yes, you have to have a minimum weight, but that just means that you can take a superbike and spend the extra weight applying aerodynamic fairings whe…

Technology is an integral part of cycling, just as it is in motorsport. There are some one-design motorsport racing classes, but they are far from the most popular. Fans like to see innovation, we like to coo over the beautiful new machinery on display. Some of the greatest moments in cycling are directly related to technical progress, most obviously the Obree/Boardman battle for the hour record. On one side a profes…

How about something in between? A rider and a manufacturer can work together to design a new bike for that rider, but for actual races the manufacturer has to build an instance of that bike under supervision of race officials and turn it over to them, and it is that instance that the rider must use in the race. Once the bike is turned over to race officials, no one is allowed unsupervised access.

That allows innovation, while making it much harder for a rider and team to cheat.

It will obviously pay for itself in terms of energy... in the limiting case, you could just hop in a Tesla and win the race.

Hm. I love the idea of a logic proof, but is this correct? In the limit the Tesla runs out of battery and you can't push it up the hills.

I meant the limit as battery / bike -> infinity for a fixed race length, not the limit as distance goes to infinity. In the latter case, the human dies as surely as the car. The race stages are only about 200k, which is no problem for the car, especially at the relatively low speeds of the bikes.

I don't know a lot about it, but Keirin racing is super highly regulated on the equipment side. Essentially everyone has to have the same bike, with there being only a handful of parts manufacturers that have to make everything conforming to a certain spec. https://en.wikipedia.org/wiki/Keirin

Essentially the original "Formula" idea.

Wouldn't that be more work than just inspecting the bikes?

What about a flywheel? Probably a net negative. What about a motor with no battery. You pedal to power it? Just wondering what the limit of "human powered" is

A clutched flywheel would probably be an advantage in many kinds of terrain. Imagine being able to spin up the flywheel from pedalling or gravity (geared) while going downhill, and then when you hit an uphill section you kick in the gear and pedal easy. It would essentially turn most tracks into "flat" tracks.

No the extra weight of a flywheel plus motor/generator would far outweigh any small advantage. The energy density is just too low for any flywheel small enough to fit on a bike. And the gyroscopic effects would mess with handling.

Why not encourage this? F1 racing fueled innovation in this manner before they went crazy with engineering restrictions

Have you heard of Group B? That's the story of why racing today has heavy regulations.

I wanna learn more and wikipedia isn't very helpful; any places I should read?

The biggest differentiator is height. I assume taller people have more muscle power hence should be put in different category.

Most champion cyclists aren't tall. What matters isn't power, but rather power to weight ratio.
