It's a fixie, a fixed gear bike, to brake you have to stop pedaling

@@eljigui9131 if you think about it though the gear ratio works in reverse too i think i haven't ridden a fixie before but if the gear ratio works in reverse then you get the same amount of torque back and it has very little torque so you're better off stopping by just letting air drag slow you down.

[@Tinker_Nerd]

Before welding, the paint should have been removed. Also, rather than cut into the frame of the bike to add the hubs for the two new sets of sprockets, new pipe should have been welded onto the frame to add the hubs. Cutting the frame to weld in the hubs creates the possibility of the frame not being aligned perfectly straight afterwards, which adds structural weakness. Also, gear ratio is way too high unless you do serious biking. I used to bike 24 miles every morning (took me two hours), my legs were huge, and I doubt I would have been able to get that bike going without struggling, or starting from the top of a hill

[@azekia]

This thing is just meant to have the highest gear ratio he could think of without making a front gear the size of the wheel itself. It's a proof of concept, not a product.

Ride any standard race bike and you'll find it already has gear ratios higher than what you can usefully pedal. With these enormous ratios the amount of torque needed is beyond what your legs can supply so you'll actually go slower than with a lower ratio. Air resistance limits speed on a bike as it goes up exponentially with speed.

Самоделка полная хуйня, и я объясню почему. Вваривание в раму, в нагруженный элемент тонкостенных алюминиевых картриджей кареток - это настолько тупо, что просто разрезать раму пополам и так оставить. Люди выкидывают рамы дорогих велосипедов, когда на них появляются меленькие трещинки и боятся их варить, посколько сварной шов или пайка будет тянуть металл на себя, создавая избыточные напряжения, которые могут привести к новым трещинам. А тут он алюминиевую фольгу в раму захреначил! Так еще и нагрузку на это дал! Я вот такую тенденцию замечаю только у азиатов, чаще всего у индусов. Они берут велосипед и всеми правдами и неправдами повышают передаточное число, прибегая к таким методам, от которых сопромат впадает в ступор, и пока он из него не выйдет, конструкция работает.

Frankly, gearing has never stopped me from reaching maximum speeds, it's always been aerodynamics and pulmonary / cardiovascular capacity...

[@GRAYgauss]

@@rey_nemaattori Agreed. If anything gearing helps because it's possible to squat 400lbs compared to 20x20lbs in a second... Also agreed, it's always my cardio endurance that fails first; it'd have failed at lighter ratios just for the aerobics vs intensity. My cardio has always been terrible, hate it, hate it, hate it.

[@rey_nemaattori]

@@GRAYgauss Gearing absolutely helps, but it always is a trade off in power required per stroke. Eventually you're going to need so much power it simply becomes impossible. Especially since you're not just pressing 400 lbs in a second, but _every second_, thats when either fatigue kick in, the muscles can't move the load or the body can't supply enougj oxygen. For most people it's easier to press 20 lbs for 20 seconds that to press 400 even once .

[@GRAYgauss]

@@rey_nemaattori Eh, bad numbers on my part. I was imagining squatting and that force that goes into pedalling when I go up hill. My point is that the human body can't move fast enough to pedal 20lbx20 in 1 second, but we COULD pedal 400lbs once in one second. For me, it's easier to pump more per cycle than many cycles, because I have terrible cardio but good mass/strength ratio. Bad numbers again, but that's the idea...The balance in my mind is most efficient when biased towards 20% speed and 80% max force rather than 80% speed at 20% force. Agreed with what you said on power, but for me I'm biased to feel that high speeds are more impossible than high torques. The fastest I can go isn't when I'm peddling like a demon, but when I'm taking about 5-6 seconds per foot to torque through and the entire follow-through feels like a rocket acceleration.

Believe me, you can try this but this project will be costly and requires welding experience. If you made this, it would not be very useful in places with hills and slopes upward. Here's some information: If you were to try to go up, it would require a ton of pushing power with your feet but it will not work. You will just go back down. The only suitable places are places with no hills and straight roads. It would work only if you were to get a push from someone because if you were to try to pedal, there would be a ton of friction and will make it hard to pedal when starting. Another problem is that there are no brakes, so if you go about 50 to 60 Km, you will be in big trouble. 💀 But afterall, good job~but you should try to go up a hill.

Put a hydraulic motor where the crack is hooked to that crank or the pedals are hooked to use a small electric motor to pump hydraulic fluid to the hydraulic motor you will achieve this speed even faster because of the high torque of the hydraulic motor the electric motor will not turn the crank it will turn a hydraulic pump which will feed the hydraulic motor the speed will amaze you you will break chains and spokes it has to be done slowly. Increasing hydraulic pressure has to be done slowly try it you will be amazed.

[@omarrama92]

Oh Dear, oh dear Lord!! 🤣🤣🤣🤣 That doesn't make any sense?? The spokes breaking?? Chain breaking?? Why not use the e-motor directly but drive a hydraulic pump and motor?? You're just loosing efficiency dude.

[@Mike-hr6jz]

@@omarrama92 i’ve already tried this and my bike will go uphill at 50 miles an hour because of the incredibly high torque of the hydraulics ,but it will break chains and spokes if you unleash all that torque at one time you would have to see it and you’d understand it. You also understand you and your E bikes are highly inefficient some of the highest tech geniuses of our time I’ve been working on these electric vehicles for decades the problem with electric cars is we do not have an electric grid that can service them without turning off the entire system or breaking it .and of course the other problem with the cars is what they don’t show you they do not have them race against In stock car racing why ?because if they have a collision they explode and you can’t put those fires out easily .people would die the public would be aware of how dangerous electric cars are .bikes the batteries aren’t big enough most of the cars have an energy density in their batteries that is equivalent to the transformer hanging on the telephone pole out in front of your house, if you’ve ever seen one blow up it’s not 🤩 pretty

Trzeba mieć siły w nogach. Ja mam szybie przełożenie w rowerze MTB a i tak na płaskim ciężko mi 50 przekroczyć, chociaż przed słynną chorobą która omal mnie nie zabiła na płaskim robiłem ponad 50.

When I noticed NO BREAKS !! My Mind - Noice Work Perfect 😎

[@sherazahmed497]

this also look cool but is it hard to pedal?

[@caiofernando]

What do you think? lol Yeah, it's very hard to pedal because it has a ridiculously high gear ratio. It's so hard that it's inefficient compared to what can be achieved with a single crank system and higher cadence.

[@sherazahmed497]

Thank you! Its like you did the experiment for me. I'm currently putting a similar arrangement, with shifters on a stretched frame.

the only thing im worrying about is going to a hill

[@viniciusmaes7292]

cara a pior parte disso é que o povo nunca estudou o fator limitante da velocidade, na terra tanto de carros motos e bicicleta, é a densidade do ar, multiplicado por varios fatores e um deles é a velocidade ao quadrado, ou seja o arrasto produzido pelo ar é esponencial.velocidade ou seja não adianta fazer inumera reducoes, o fator vai ser sempre quanto torque um ser humano consegue realizar, em detrimento da seção em atrito pela sua area.

[@wiltmarlonelao]

You need to add an electric motor to assist you with your low end torque to make this more viable. Once you've got your bike running, you can just pedal away and recharge your battery at the same time.
