Aha, another nice physic lesson XD
This is why "indexed steering" killing your "no hands" riding joyments! -
They drink coffee
-
look mom no human
-
And if you're a six year old named Calvin, the bike will try to eat you!
-
That was really good, thank you for creating that video!
-
0:17 Angular momentum is what keeps a bicycle stable, not conservation of angular momentum!
-
Is this why you can ride your bike without hands.
-
Gyroscope Affect.
-
i hopped off my bike going down a hill and chased it to the point where it slammed into a truck and i picked it up and biked away
-
Can you explain this video one more time to write
-
YOU MISSED OUT A FACTOR ..... the curved cross section of a bicycle tire.
If you have two wheels mounted on the same axel and one wheel is smaller than the other you will aways steer in that direction (round and round in circles).
You can think of a bicycle tire as being three wheels on the same axel. The two outer wheels (the edges of the tires) are smaller than the inner wheel (the centre line of the tire).
This is also how you steer when doing a wheelie. -
I hear aspiring rocket scientists are encouraged to design their own bicycles before designing rockets, so they get a handle on the absurdly complex and detailed physics behind everything. Sadly, bicycles are complete magic to me. I could never design one myself and truly know how it works. Guess rocketry is one more dream down the drain...

bycicles are very usefull, I love them :D
-
i just kept hearing "GHOST RIDE THE WHIP!" in my head all through this video.
-
But what i wanna ride is you. Not the bikes
-
is that missoula?
-
at approximately what speed does the bike have to be traveling to maintain speed and not crash?
-
Illuminati confirmed.
-
Am I not getting it or are those first two factors the same thing?
1. This axis is behind that axis
2. That axis is in front of this axis -
Whenever the bike ran i assumed it as a calf!
