making super fast bike

making a fast bike casero ever build

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.😁

раскрутить колесо до 70+км в ч, можно и без этой приблуды, хорошо бы посмотреть как он эти 70 выжмет сидя на велосипеде, хотя бы по прямой.

I don't think it makes much sense. power and speed are related, above a certain limit you simply don't have the power to pedal

[gutzon]

Teóricamente es todo posible. sin embargo, actualmente las relaciones de engranes para ruta comercialmente está 53/11 es 4.81, hasta 60/11 es 5.45 con esta última relación superas los 40km promedio. Así que trabajamos con la relación 28/14 x 52/14 llegaríamos a 7.42 teóricamente, sin embargo la cadencia sería lo quizá uno no pueda sostener el rpm . Es un buen multiplicador de velocidad pero no practico para el cuerpo humano.

FYI, there are already “multiple chain rings” in the market. Even your invention makes more friction because of the additional chains.

The limiting factor are the legs. I don’t see any advantage compared to a conventional system with two or three gears at the front.

[michwoz]

Fun fact: gear ratio is not a limiter of bicycle performance.

[dorron]

Dude giving he's weak legs more work.its all in the legs

[alexyanson]

Regardless of gear combinations to increase speed, your speed will still depend on human power input.

Leaving those freaking ball bearings angers the shit out of me

[PP-cmre]

Increasing the gear ratio definitely gives you potential for more speed. But you’re still putting in the same power with your legs. You’re not gaining any mechanical advantage by doing this.

А теперь в гору и против ветра... Вот тут, думаю, все преимущества сойдут на нет.

[ironfrogpress]

Very interesting as for a unique crazy build. But I don't understand how this clumsy rig would increase speed or perfoemace.😉

[jhonbanner]

Me encanta, la idea es como la dinámica de incrementar la fuerza o esfuerzo físico auxiliado de la ingeniería de los piñones, así como los cambios.
Muy bien pensado.
Definitivamente hay mucho que mejorar e inventar.
Mil felicidades chicos por este gran aporte será toda una revolución en las bicicletas. Mejor dicho la vuelta Colombia nos quedó pendeja.😄.
👍🇨🇴🙏.

Love the precision welding, and it goes like a cut snake. I saw you passing two or three buses!

[snowcrest]

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.

[Rob_aka_CancelProof]

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)

[santiagopfingst]

You are a genius man, that is the future of the transportation👌👏👏👏👏💯💯

Question is, does it weight less than a 80 or 90T front chainring+chain links?
And the increased complexity equals more prone to failure.

I like electric bikes. They have serious acceleration. I was out biking and I saw a woman on an electric bike. I have to admit it was pretty cool to see her take off.
