[@jaye1967]

I'd guess somewhere over 242k time the force you normally put on the pedals to move the bike. Now the question is witch part of this system gives out first. Some part of your legs, the pedals, or one of the chains.

@@IndianaJones1 No, in this case there is no difference between theory and practice. In theory you can see that the torque needed to move this thing would be massively impossible, and in theory you can see that we don't know yet of any material that could withstand that stress. It is just that in "his theory" he didn't take into account any of the physics of this problem.

[@GreenMeansGOF]

[@3Black.1Red]

For those wondering how much energy it would take to pedal that bike to such a speed: Using only classical mechanics (everyday practical equations), it’d take a very large but finite about of energy per unit of time. But if we account for relativity (less practical but more realistic), it would take an infinite amount of energy per unit of time. As the speed approaches light-speed, the energy it takes to accelerate the bike any further would approach infinity (like a curve on a graph approaching its asymptote).

You guys don't do that too? I also track every photon of light that comes from the sun toward earth. There are currently 43,455,562,916,564 photons of light that are between 40 and 60 percent of the way to the earth from the sun, and I estimate that a little less than 80 percent will arrive at earth, whether they bounce off the atmosphere or come into the atmosphere.

[@Kensuke0987]

It's not even friction. When you go from a higher gear ratio to a lower gear ratio, the torque also goes down. You simply won't be able to pedal the bike. you may as well push a mountain. In the case where you can push a mountain, the gears and chains further up will break first if the axles nor the bike doesn't already get destroyed.

Two observations: First, 90 RPM gets you significantly faster than the speed of light (bike = 27,700ish Megameters/minute vs c = 18,000ish Megameters) = bike can reduce its velocity by almost 25% and still be faster than _c_ )...so an RPM of around 68 should achieve this (and would be much easier than pedaling at 90 RPM; and Second, since this is obviously a working FTL Drive, I suggest someone patent this idea ASAP before Temu gets hold of it!

There is no bell either, so it would not be street legal in the UK. The fact there are no brakes either might be OK for fixed gears, as you backpedal or hold the crank still to stop the rear wheel.

[@IvysChannel-kb9sn]

And the only thing stopping that from happening is the amount of energy you would need to move the pedal

[@johnh539]

I like silly maths, I once calculated how long it would take to reach light speed accelerating at the rate of acceleration due to free fall on Earth (To 4 decimal places). 3 Assumptions: 1)our weight on Earth is an equivalent to the force through our feet standing on an accelerating space ship with no other gravitational factores. 2) No terminal Velocity.(And to be honest a v. good gear box🧐) 3) The resultant Jurnee time is for those on board and thus nothing to do with relativity. I only bothered once as it was just a game but I came up with 0.9 of a year.

Well, I don't know about you, but I would not ride this thing even if the frame was strong enough and my legs had infinite power. Calculate the speed at which the gears would rotate and the location of the gears adjacent to ones right femoral artery. Also the wind force might be an issue, I know it it the biggest source of friction riding a bicycle at normal speeds and it increases at the square of the velocity.... The math is fun though!

[@solarwind]

This reminds me of one of those gear machines where they say the universal end when the final gear turns or it'll be like 100 million years. The problem is it's made of materials that would decay well before the last year can turn this bike also probably does maybe 100 km an hour. Maybe 120 downhill and it'll be lucky if it doesn't fall apart. It's true advantages. Probably just how easy it is to get it up to speed and maintain speed so you probably won't have to pedal as hard

[@deepeshgarg9460]

The axle and wheel will going to breakdown even at half speed of the light and the tire can burst if it goes more than 200 km/h speed But only few people's who do regular cycling and have good legs can pedal this cycle because it will take a very huge force even to rotate an inch
