[@fuzzywzhe]

It's been done a long time ago with just higher gearing ratios. A bike designed for a velodrome has extremely high gearing ratios, and it's not uncommon for racers to get over 50MPH with people even being killed during events. The high gearing ratio is very hard on your knees. I used to bike a lot when I was younger, when I got into my mid 20's, biking in the lowest gear all the time started to effect my knees. Trust me, you don't want to ride something like this once you start to loose your cartilage.

[@-oiiio-3993]

[@vanshbhavsar9024]

We need gears in it and it will be good

[@fuzzywzhe]

@@vanshbhavsar9024 You probably don't bike a lot, but if you have a bike, try to bike in the top gear at all times. This WILL grind your knees. What is demoed here is 10 times worse. I used to bike a lot, and I was always in top gear unless I was climbing. This is an interesting example of gearing ratios, but there is a reason we don't have them at this level. Believe me, you will age and get old, and this bike destroys knees. I know 30 years is hard to imagine, but if you don't do anything incredibly stupid, you'll be here in time and be astonished you are. Live well, and live long.

Great you've discovered gears.... Can achieve similar ratio by enlarging front chainring/smaller rear freewheel with less parts & friction.

[@danjames4086]

The principle is good, but there are lots of problems here too. Firstly the rear freewheel he removes is probably a 16 tooth. It would be far easier to replace the rear wheel with a freehub design which would allow an 11 tooth sprocket. Similarly it's also easier to increase the chainring size at the same time. Secondly the stresses going through the chainstay will be enormous....far more than the tubing was designed for. However I like the concept though. To have a secondary gear would allow for incredibly high gear ratios (or low ratio too). Interesting for record attempts etc, or recumbent bike that achieve high cruising speeds.

Two details. one.-. The first chainring has 48 teeth, the second has 39 and your sprockets have 16. According to the assembly, for each revolution of the pedal, 7.3 revolutions of the wheel are obtained. That can be overcome with a 60 tooth folding bike chainring paired with an 8 tooth BMX sprocket. That is to say, Hera is not necessary, on the other hand there are those who have installed huge turntables to have much longer developments. 2.- A lot of force is required to move that transmission. Even professionals use much shorter developments. Example Time trial 58-11 (5.27 wheel revolutions per pedal revolution) Route 53-11 (4.8 wheel revolutions per pedal revolution) Xco 38-10. (3.8 wheel revolutions per pedal revolution) Bmx (between 2.4 and 3 revolutions of the wheel for each revolution of the pedal

Подходит для ровных дорог, а вот уклоны тяжело будет преодолевать на таком. Потому и придумали системы переключения передач типа Shimano. Если нужно выжать весь скоростной потенциал, достаточно просто поставить 7- или 8-ступечатую кассету с минимальным числом зубьев на звезде 11, а ведущую звезду поставить 52. Тогда на 1 оборот педали будет приходится 4.72 оборота колеса, что вполне оптимально, в зависимости от диаметра обода.

[@Serzh11652]

Да не будет это работать и на ровных дорогах. Проблема разгона велосипеда далеко не в передаточных соотношениях. Ничто не помешало бы установить переднюю звезду хоть на 100 зубьев и разгоняться до сотки. Куда вы денете сопротивление воздуха и трение качения? А именно они и тормозят велосипедиста, причем их сопротивление растет тем быстрее, чем больше скорость. Так, например, при скорости 20-25 км/ч сопротивление воздуха не особо ощущается, едешь расслабленно. 30-35км/ уже тяжелее, 40 и выше- приходится "продавливать" воздух, это понятно уже по трепыхающейся одежде и жуткому ветру в ушах. Воздух на больших скоростях уже похож на жидкость в некоторой степени.

Parabéns!!! Ficou ótimo 👏🇧🇷

Good luck getting the thing to even get started let alone any kind of stride

[@ZeyZard]

hope that there will be a part 2.. for you to continue working on the modyfi and additional gear..ofcoz for the hilly and uphill road.. . you are the one who works on it..I bet you can do it sir..👍🙂

[@James_Knott]

The next part will be about modifying the legs, so they can manage to provide the torque through such a high ratio. Anyone who's ridden a multi-gear bike understands that.

[@ZeyZard]

@@James_Knott like adding the second legs for the middle primary ..then just change leg into high ratio ...

[@ichbrauchmehrkaffee5785]

@@ZeyZard Or just invest in a derailleur gear shift. It does what this design does, but much better in any way and it also does more

[@edsonmarcosgarciamelo3905]

Maravilhoso projeto .Parabéns.

[@mouseshadow-f5k]

An engagement for this gear would be great for an ebike. You lose torque and gain RPM, so for flats you could kick in the overdrive, but be able to switch when you hit hills

[@sinapsemecanica1376]

Excelente vídeo. Estou tentando fazer o mesmo, mas usando o sistema de polias, para distribuição de força.

[@nonocurios]

Posta aí seu projeto

[@sinapsemecanica1376]

No momento eu não posso, mas assim que tiver pronto, vou divulgar.

[@namizitap]

Eso ya lo planee tiempo atrás. Pero tiene desventajas , es que requiere el triple de fuerza de lo que usamos con normalidad , las piernas se cansan rápido ,y no es conveniente para uso constante

What is your speed in 20 degrees uphill ? Could you get the same speed on level ground as shown in your video if you are going uphill? please answer, thank you......IF YOU WILL NOT ANSWER THE QUESTION THAT INDICATES THE ANSWER IS NO......i could imagine MAYBE you cannot even move.....PLEASE TELL ME I AM WRONG !......you are an inventor you supposed to know that !

[@johnnymarquez]

me parece excelente se aliviana más el peso porque no tiene cambios traseros, y ni palanca para plano cambio delantero podía sería probarse un segundo plato a ver y en vez de una taza central podía ser con una rolinera para tener un estilo único de bicicletas de plano y para ir a trabajar me gusta aunque subo algunas subidas gracias por compartir Nuevo seguidor apoyando thank you

[@seymurquliyev6315]

Great idea congratulations

[@gabymanito7984]

Lo pense antes como un proyecto no sabia que alguien más lo tenia en mente me gusta ya que al llegar a una velocidad alta y ir relativamente a pocas vueltas la podes mantener durante un periodo mas largo

[@MrHakurei]

pues en realidad te cansas mucho mas cuando pedaleas mas lento, lo idoneo es tener una cadencia alta, con platos grandes y piñones chicos es poisble ir muy rapido y descansado pero a muy altas pedaleadas

[@user-gj2wj6hm3j]

No tiene caso ese invento para eso son los cambios de estrellas es perdida de tiempo esa adaptación Tonta

Gran invento, pero requiere también un aumento exponencial de la energía para poder mover la bici más la persona

[@donguadalucio1405]

De bajada funciona bien. De subida no. Además, las bicicletas de hoy en día ya traen hasta 24 cambios. No es necesario hacer esto.

Pq vc fez a mudança da catraca traseira?

[@whiskeybuilder6335]

Great setup. Maybe think about gearing the primary drive.

[@spackelskrapan]

Have you considered getting a bike with gears or are you just going for the land speed record in the human powered category?

[@TheDarknessConsumesMe666]

Would it be difficult to change/ fix the chain should you have to?

[@levharagezyan4596]

А ещё представляю что будет, когда с задней передачи цепь слетит и в спицы попадет.

[@izzabelladogalini]

Great for increasing the speed your wheel turns when it's not pushing your bike (and you) along the road.... no free lunch, increased ratio equals increased torque to turn it.

[@ВалераАрсентьевич]

По ровной дороге можно ездить.А вот на горку понадобится приложить большое усилие на педали.Так что процентов 70 людей даже на небольшую горку несмогут заехать
