It doesn't but might as well have some type of tech

your attempt at adding "tech" to BT is the worse attempt ever... if people want to learn tech they need to read the stickies that raul made. thats real tech. not a fucking video post. we have a video section on TR, might as well put this shitty ass video there.

I mean the queer is wearing a reflective vest during the day in an open parking lot riding a bicycle, i can't take him seriously.

. In a motorcycle, centripetal force is generated by the friction between the road and the tires.

what?

The two actions work against each other and the bike is balanced while being leaned over.

You ever balance something that was tall? a big stack of cardboard boxes or a broom sticking straight up in the air? If the broom starts to lean to the left, you quickly move the bottom to left to "get under" it. If it goes to the right, you move the bottom to the right.

Imagine if the bike was not moving. You lean the bike over and let it go. It falls over.

Now, if you had a way to pull the tires quickly in the direction of the lean, you could balance the bike back upright.

Then, if you were able to move the tires quickly in the direction of the lean, but only quickly enough to keep the bike from falling any further than it already had fallen (let's say 20 degrees off the vertical), then the bike would stay leaned over because the force you are applying to the tires is exactly equal to the force of gravity on the Center of Mass.

I've read this stuff in books and its been awhile ago, but it feels like you have some shit out of wack. but I'm not going to take the time and research it again to find out what.. so I'll just move along now.

It's not stuff the average joe is exposed to all the time. I don't blame anyone for not understanding. I had to take Physics I/w Calculus and Physics II/Calculus, so it comes natural for me to think about it in those terms.

Besides, it goes a little deeper than what I wrote. There's torque, drag, angular momentum, and a bunch of other elements happening all at once.

Of course, nobody cares about the physics when what we really enjoy is the riding.

Thanks for at least reading it! HAHAHA
