You can increase the final gear ratio as much as you want. But the power in a pair of human legs i.e. a cyclist, remains the same. (higher gearing requires more power to push the pedals). So it doesn't make you cycle any faster if you're not on a smooth downhill and you have gravity to assist you. Then nevermind going uphill ..... you can forget about that. Get off your bike and push it while you walk.😁

The "laboratory" conditions presented here do not account for rolling resistance and wind resistsnce. Your top speed will be no faster on flat, level ground than regular gears, assuming regular gears are already geared higher than the rider's strength. If it did work, I could gear my car to go 1000 MPH by just putting in high enough gears.

Useful for the bros who don't skip leg day! (~‾▿‾)~ Edit : on another note, modding it with a 250W rear hub motor and a controller in a pedalec configuration might help those who skip leg day as well

А теперь в гору и против ветра... Вот тут, думаю, все преимущества сойдут на нет.
-
Still the same as normal set up, human power is still needed...
-
Easy to turn the crankset when the bike is on flat road, but with a few D+ you will need to buy new legs. With 54-10 it will be already very difficult to crush the pedals
-
Fun fact: gear ratio is not a limiter of bicycle performance.
-
everything starts from the legs, you don't have strong legs, the invention has no value😂😂😂

Belo projeto! Agora falta botar um freio ABS pra segurar isso daí hein 😁
-
Regardless of gear combinations to increase speed, your speed will still depend on human power input.

Love the precision welding, and it goes like a cut snake. I saw you passing two or three buses!
-
Really cool! you seem to know your tools. I live in a fairly flat city and I spend most of the time in the highest gear ratio, I've always wondered how would be to have an extremely high gear ratio like that and this design is way more compact that just adding a huge gear. Also I would try to add an electric motor to that bike.

How refreshing it is to see somebody who makes YouTube videos who actually knows how to weld a bead rather than just multiple tacking / sloppy spot-welding. Great Job 🎉 (especially compared to everyone else I see on these videos)
-
Nice work! What's the highest gear ratio? This would be great for bikes with smaller wheels
-
This is a great video, I'm considering this for a fixed gear set-up. Thanks for this...

Nice brother ❤️

Может, я что-то не понял, но в чём смысл? Число зубьев задней и дополнительной звезды одинаковое. Т.е. передаточное число 1:1. Соответственно, эффекта не будет. Только потеряем на трении. Да и смысла в этом нет, т.к. большинство людей не способно крутить педали с нужной частотой (80+ оборотов в минуту) с передаточным числом 3 и больше. Тут уже нужен электромотор.

Parabéns pelo projeto! 👏👏👏👏👏

Wow 😳 that's one hell of a 🚲 bicycle 🔥🔥🔥 BEAST 👹

There are bright minds in every country but they're even brighter when they make it happen.
