You do not keep a bike upright by steering. The bike is designed to stay upright and your effort is mostly damping. Don't feel bad for not knowing, there are PHDs just as misled.

My bike has two wheels at the back I do not know why

HOW DO I STAND UP A LEGO

I got it on they first time

How A Day Turns Into Night? .Why?

I love your video can you make one on why is the moon out during the day:-)

I'm here from the adult Scishow getting answers for things I'm to embarrassed to ask about

My son DJ wants to know, how do starfish find food if they have no eyes?

January, six years old, would like to know why we have names.

The weird thing is that you need to steer left in order to lean right so you can make a right turn. Bikes are weird. I recommend watching the minutephysics video for a more sciency and head-explody explanation ;)

can you tell how dose compass work pls thanks for this video

How is possible then that remote-controlled motorbike toys did not need any pilot at all, if not a mere puppet?
It is not the arising of gyroscopic forces that prevents the bike from falling? This would also explain why we need to go fast!

You forgot to mention that going faster allows the bike to stay up better thanks to the gyroscopic effect.

Thank you for this great video. Just what my little one was hoping to see.

What are plants made of and how do they work?

I would like to add that at high enough speeds, you don't even need a human to keep the bike upright. At high enough speeds, if the bike is inherently stable as most bikes are, its stability will either assist you in keeping the bike upright if there is a rider, or keep the bike stable on its own without input.

This is explained in a video by minutephysics here: http://www.youtube.com/watch?v=oZAc5t2lkvo

Tell us about more meat eating plants

(age 23) positioning of weight has a lot to do with maintain balance and keeping the weight centered is key. As an experienced rider, I use the angle of my bike from the ground to make sharper turns and apply a counter angle to return. When i am doing this i am shifting my body weight to be inline with the bottom of the wheels to maintain balance with the angle. over time the very minor adjustments become unnoticeable and become smaller this makes the path of travel more straight.

I remember when I was learning how to ride a bike

But the strange thing is that bikes can balance themselves even without a rider, as long as they're moving fast enough. I imagine that has something to do with angular momentum, and the fact that if the bike starts leaning, that will also help it turn and regain balance as long as it's moving at the right speed?
