An over-engineered solution to a problem that nobody had.

I have a friend who stays upside down for an hour every night to compensate for his body staying upright the entire day. This bike is for him.

Clockwise rotation is meant to continuously tighten the freewheel. By pedaling reverse side, you now untighten the freewheel combo. Not a real life solution but fun :)

Forward pedal = Low gear. Backward = High gear. Thats all. Only two gears while original got set of gears. One good thing about this design is using dual chain where if one fails, you can use the other one. However, since one of the chain always rub each other, there is possibility of premature failure to the whole system because one chain rubbing each other chain and the other chain taking extra load due to friction created by the other rubbing chain. Will it slow down if pedalling in reverse - NO since the freewhelling unit both set to freewheel in reverse. Edit: Best possible use case: Create some youtube video.

Love the MELIDA frame and the SIHMANO wheels 🙂👍

Totaly usless but briliant at the same time . well done ;-)))

Only legends know this video will blow up soon

This method is or at least was very popular in some places, it is called retro-direct chain drive. Usually used on delivery cart type trikes.

Fun project and great idea. It wouldn't be for me. I have problems with twisting my Revo shift the wrong way nevermind being confused as to which way to pedal.

Какой замечательный треск стоит при езде на этом чуде! Разверни ещё сиденье в обратную сторону и катайся во вертикальным стенам!

Bro you're genius you can change gears depending on the direction you peddle. Badas!

As James May always said, "It's an ingenious solution to a problem that should have never existed in the first place"

Does this eliminate neutral? Like you have to stay pedaling versus just coasting without pedaling?

I am wondering how does it sounds like. When no pedaling both cassette hubs clicking? And when you pedal one way the second hub clicks and when you padel other way the first one clicks?

When Reverse pedalling. Does it make the Bike to slow down?

I'd be worried that if it binds randomly at any point of hard riding and it snaps then it's twice the length to wrap around your wheels and frame at speed. Quick trip to face grind town.

So whats the difference from the OG set up on bike ? Is that bike name a ripoff of Merida ?

Great work! “there is always - another way” next project: a john searl seg (warp speed) drive generator (energy pump) for intergalactic space travel. yes, star trek is history!

would it be easier to climb a mountain backwards with the crank?😮😊🎉

😀Super creative 🚲 Thank you very much! Good day!

I love to see how many bicycle experts are out there. This content section is full of them.

Cool, and would be a good educational tool. Real question is, how do you service the freewheel you welded the other on? Why not run a Fixie? Thats going to be a noisy drivetrain too.

As advertised easy to Assemble looks great

What is that awemazing camera transition at 1:48?!? It’s so cool!!

This bike is totally insane amazing at the same time thanks you inspired me

Nice invention bro...keep it up👍👍

Wow! It's a brilliant idea. That's great.😊

I thought about this for a drive on an e-scooter, where you can have the reverse motor direction drive a lower gear for steep hills.

The dude is without a doubt a genius but I can't believe he painted the chain

when IQ exceeds einstein...😂

Can you fit a derailleur in there?

So if he were to go backwards, he wouldn’t have to pedal right? Since the pawls aren’t engaged

Y la consideración de los esfuerzos de tendones y ligamentos de los músculos posteriores durante el esfuerzo? Y la columna vertebral, tolerará ese esfuerzo? 😏😒😌

So what did this solve again?

Wonderful mechanical skills, but this comes under, “everything old is new.” First patented 120 years ago.

Sihmano, Melida 😆

great camera work my friend

Place a slide between the crossing chains for smoother operation.

Honest question, what did he achieved more?

It's a good idea for 2-speed non-mechanical changing system. I would have the lower gear (maybe 20 teeth) go counter clockwise and the higher gear (maybe 10 teeth) go clockwise. Good job

Watched the video, read the comments. This was the more complicated but visually more impressive alternative to a "retro-direct" gear system. As one viewer pointed out, the idea is from the start of the 20th century. So before any type of gearing system we know today. Bikes were all single speed. With the retro-direct you could have two speeds. That was the point. All this guy did was reproduce an idea for your interest. Although I must admit that bike and parts got butchered about a bit. About six years ago I modified a single speed into a two speed using the other, simpler system. No cutting, no welding, all nuts and bolts using standard bike bits. One gear, backpedal, for starts and slight uphills. The other, normal pedal action, for crusing. The freewheel element was maintained for downhills. You couldn't walk the bike backwards though the transmission would lock up. What was the point? Among other things to see the look on other cyclists faces as you went cruising by back-pedalling. Fun days.

what to do to make it harder?

Was hoping it would do something different but thanks. I have some ideas to think about.

Осталось найти этому практическое применение)

Осталось ещё второй руль под седлом поставить и будет полный реверс)))

Прикол, все говорят поменять, но вы видели как деревенские гоняют на велосипеде. У них там цепь ух как растянута. Как ржавчины дофига.

"Hands it to a friend who's never had hand breaks

Pergunta boba, qual a utilidade?

"Melida". The almost-copyright-infringing brand name is as brilliant as the mod.

Сварка 4 точки 👍 гениально. А потом на алиэкспресс.

Creative, but impractical. Other than maybe those times when you first start to pedal with your pedal in an awkward position, what benefits are there? More parts, more mass, less efficient.

This IS Not possible for Bike with gearshift right?

Esse projeto ja conheco a mais de 30 anos.. Um conhecido meu fez....

So that’s what the call a 2x drive train!

creative idea big like

Jajjj me gusta como juegas ,es divertido y no pesa .gracias y un saludo

Is this bike faster then regular bikes ?

Not insane, brilliant. Pedaling backward is a complimentary exercise.

Using your leg muscles that way will will cause injury. I love the spray painted chain too

"Mechanical full bridge rectifier" - Me, 2023

how will it reverse?

That’s a fun innovation!

nice "cugui" pants. 🤣🤣 4:55

Bardzo ciekawy pomysł, bardzo prosty, a jednak skuteczny, co prawda łańcuch się krzyżuje i haczy, ale to szczegół techniczny. To rozwiązanie może być połączone z silnikiem elektrycznym pod siodłem, który może sobie pracować w dowolnym kierunku :) ;)

Wonderful n Amazing 🌹❤️🌹

"What gear do you use?" "all of them" 😅

Eu gostaria de ter estas máquinas e ferramentas para tentar criar essas idéias , o cara é um gênio, parabéns!

Creative, but won't the crossed chain create friction?

Guys... So many of you say its creative and all those ... I respect that But what is the real use of it ?

Would’ve loved to hear it

I would like to see a unicycle version with a forwarding petal of 1/1 and the reverse petals to 2/1 wheel to the crankshaft ratio. Possibly toss in the combination of multiple ratios. Please let me see and I'll watch hours of video.

Good work

This guy:- why not have a mechanical moonwalk

Nice vadio bro I am Bangladeshi 😇🥰🇧🇩

What is the top speed? 🚴

Loud music most likely is covering up the noise that the chain is producing rubbing it's crossing.

I thought you were going to make it so it literally could be peddled in reverse. You would probably need trainer wheels on the front to avoid spending most of your on your butt. However... Being able to ride reverse on a tricycle is definitely a concept that would sell 🙂

Any benefit from this?

Esta bici vale millones y millones con esas cadenas

Look at the brand of the bike...Melida...😂😂

man Chinese ppl always have the chadest ideas 😎😎😎

What about relaxing my leg.... I think it’s impossible to stop paddling when riding as we ride on bicycle...

what was the point to add the length of a chain or speed

Sweet, now add dual steer to that bike

Электро ускоритель поставь на обратную 👍

Please make a musical bike that plays a notes using metal tines on its wheels like a disc music box

Wait... Merida? Or Melida?

Your Video’s Is Whats Insane,lol….Thats Just Nuts,I Saw A Guy Make A Projector From A Cell Phone,Would Love To See What You Would Come Up With🙏🏼❤️🌏✨🔭

Obligado la cadena tiene que rosar

'MELIDA' LOL

I think it would have been better to see him pedal off from a stand still postion in reverse rather than the normal way.

Sensacional uma pedalada Vale pôr 2 show de espetáculo 👊👍

Một sản phẩm mới lạ độc đáo chứa rất nhiều chất xám xin cảm ơn đã chia sẻ

Actually ducking genius way of shifting, freewheels really are underutilised

No entiendo . Al pedalear hacia atrás que hace?

Decreasing chain size also works and only takes a few minutes hahaha

Dope💪

Exelente idea para un problema que no existía 🤩🤩🤩

Where did u buy these Gugui panst lamo

Well, useless or not, with 3.3 million views it got the bills paid. I hope your success continues. Seeing that it was only 5 minutes long, I went ahead and clicked on it. If it's short, I'll watch it. It's the commenting that uses up my time, oops.
