How to Make a Speed Bike

I'll show you how to transform a super-fast bike with multiple chainrings, and it's got really big gear ratios, so it's super fast!

My channel has just started, there will be more interesting DIY productions in the follow-up

This also my idea last 5 years ago, , I don't have tools enough or money to do this. Congrats Bro..

maybe for more efficiency try increasing the weight of the pedals in this way you wont waste much energy

多用了兩個鍊條帶動 傳動上應該有所損失 即使沒有
鍊條用久了的故障率 3條就成了3倍 (小時候家裡開腳踏車店的 來維修的最常見的是鍊條鬆了)
應該不如齒輪組合 腳踏第一齒輪帶動第二齒輪組(甚至第三齒輪組)
由第二個齒輪組用鏈條帶動後輪齒輪組
尤其省略了後輪的變速齒輪組附加的鬆緊器(我忘了正確名稱) 鍊條更容易出問題

給一個小小的建議 或許可以試試"加個翅膀" 可以調整偏向
低速降速時 三角鴨翼前朝下
想高速提速時 前朝上 利用空氣浮升力減少重量

Fast bike! I'm sure that fitting one of the gear wheels in lieu and place of the saddle would have made it even faster!

[urlocalbeanboy]

4x the chance of ur chain slipping off lol

Now make a chariot style trike and DOUBLE IT!

It's all torque vs number of rotation. But the obvious thing that is hidden is that when you get such high speeds, you will require tremendous effort to pedal it at start to gain momentum. It's a trade off. Nothing is for free.

Imagine how fast he goes on the bicycle ☠️

[MrCFH]

Dang getting a pant leg stuck in that must be a beach!

[striderkenshin]

The real question is how many watts is he outputting to get that speed. He's fighting a lot of wind as well
due to his riding position.

People that skips arm day: *Climbing a hill with this will be my goal*

[_stller_]

Now imagine one of the chains goes off during speed test on the road

Hello good afternoon. One question, which application does it use to measure kilometers?

[graphixkillzzz]

one to two reduction three times is eight to one from the pedal to the rear wheel 🤔 you gotta put a lot of torque at the pedal to get that moving. but, once moving, that thing will put out some gnarly velocity 💪😎👍

with this i feel like i can outrun the dog that always chase me next street

[Kraftik]

Would be interesting to see it with an electric assist

[RobertJensen-sotw]

Do this with a 3 wheel recumbant tricycle (like a Greenspeed) and run the extra chains out the front (both sides of the frame) and then back to the derailer via a spacer sprocket and you will hold 45km/h for an hour.... easy.

Ноги велосипедиста только жалко, а так зато едешь со скоростью автомобиля

Clever, but he definitely ain't riding that thing uphill.

[roerin]

basically it’s like pedaling on 30 degree angle uphill… but on a flat surface.
