The UCI rules are... extensive; it's definitely disallowed [1]. Even if not, there's a rule along the lines of "any technical innovation must be pre-approved," and I am pretty confident it would not be. [1] Probably by article 1.3.010: "The bicycle shall be propelled solely, through a chainset, by the legs (inferior muscular chain) moving in a circular movement, without electric or other assistance." - https://www.uci.org/regulations/3MyLDDrwJCJJ0BGGOFzOat https://www.uci.org/regulations/3MyLDDrwJCJJ0BGGOFzOat

Therefore you put the motor inside the leg muscles

> Probably by article 1.3.010: "The bicycle shall be propelled solely, through a chainset, by the legs (inferior muscular chain) moving in a circular movement, without electric or other assistance." Well that just says you need to build your regenerative braking system into the chainset. Use of stored energy is obviously allowed or else you couldn't make use of gravity when on a hill. > Even if not, there's a rule along the lines of "any technical innovation must be pre-approved," What innovation? Mechanical energy storage is ancient technology.

    > The actual unwritten rule is not so much against inventions, as against having any fun. The rules, written or not, are about trying to adjudicate a competition of people, if you want a no holds bared technology based competition nothing precludes creating a different one (or participating in one, there’s no dearth of alleycat races and other odd events like the singlespeed world championship).

      I'm not against rules. What irks me a bit is that they are supposed to be about bikes, but in reality they are only about bikes that look exactly like the ones they have in mind. Eg (if I remember right) they also specify a minimum wheel radius, because at some point people started doing well with those, and the people in charge didn't like that. And they might as well be right: they have an entertainment business to run. They don't care about finding the best or anything like that.

        I disagree that the sport is about bikes. I think the sport is about cyclists. The olympics is particular is built around human athletic competition not technical competition. How do you find the best cyclist if the quality of the bikes is wildly different? In any experiment, you have to control for the factors other than the ones you're looking to test. I don't think its fair to say that they don't care about finding the best, they're just trying to find the best of a different category than you're interested in. As GP said. There is also space for different competitions about technology (in motorsport, formula 1 has both a driver championship and a constructor championship which is about the technology).

And even then the technology is severely curtailed, it has to compete within a fairly restrictive design envelope.

    Even if recumbent bikes were not forbidden, no one would use them. Cycling is a sport of dignity. See also, underhanded free throws in basketball, which are strictly superior to the usual free throw style, but lack dignity and are embarrassing to perform so no one does them.

  > Well that just says you need to build your regenerative braking system into the chainset. The chainset is a transmission device, it will store a minute amount of energy elastically, but anything beyond that will get you punished.

  >Use of stored energy is obviously allowed or else you couldn't make use of gravity when on a hill. You've walked past gold in search of silver. A biking competition that disallowed the use of gravity would be wild. What would that even look like? How could it be run? Compressed air jets to maneuver bikes onto friction platforms? Entire courses built into the non-rotating sections of space stations? Racers suspended on bungee cords to counteract natural forces?

    It would look like a perfectly flat track race. No hills. No use of gravity on hills. Solved.

      so grass track racing? It was more popular worldwide but is still very popular in the Caribbean and Guyana.

    A device could be affixed to each bike that measures wheel speed, as well as pressure cells for the pedals. Any energy that can't be accounted for from the pedals would result in the brakes being automatically applied. Advantages from wind would also be negated, but I believe that's in spirit of the rule. At first just a single wheel speed sensor could be used, but once the meta evolved to doing stoppies/wheelies on downhill sections both wheels would need to be fitted with one.

      New meta: Jump the downhills.

  The UCI banned some handlebars that were regarded as too far forward, they've banned elbows being too high, they've banned handlebars pointing slightly inwards. They'll ban anything that's even slightly out the ordinary and with no reasons given.
  - freejazz 2y ago
    Most of those were banned for safety reasons, what are you talking about?
    - danielbarla 2y ago
      Not the person you responded to, but there are a number of changes they have banned, arguably for being too effective. Aerodynamic covers are not usable, recumbents are not usable (especially not ones with a cover, which are significantly faster). I mean, I kinda get it, it's a traditional upright bicycle race where they want the human factor to dominate. But somewhere in there's a ~65% performance improvement they are leaving on the table (that is the difference in the "1 hour distance record" between traditional and fully faired recumbents).
