How do you control which direction the bike moves if you start it from a complete standstill and no other force is applied to it (besides the force of the pistons on the crankshaft)?
thanks everyone. i understand the breadth of the topic now. i have one more question though.
how do you control the direction of the rotation of a crankshaft?
I understand this, but how does it cause the motor to turn that way?
Say there is a 1 stroke engine, what causes the crankshaft to rotate in the same direction every time?

In the diagrams on this site, there is...
Sorry, I meant to say a rotating crankshaft attached to a piston through a connecting rod. Of course clockwise/counterclockwise depends on the side you're looking at, but I was just giving an example of one viewpoint of the crankshaft. Sorry for the mix up!
Let me clarify:
Why do pistons...
Why is it that pistons always, say rotate clockwise, and not counterclockwise?
Is there some sort of imbalance on the piston that causes it to only move in one direction?
The main thing that i need with the spring is for the tile to return to the original location. The exact distance it drops is not important. I'm thinking that memory foam would have a hard time holding this weight. I think that i might have to stick with springs. Do you guys know any places...
Hey!
I'm trying to find a more cost efficient alternative to a spring for a design that I'm working on.
Basically, I'm designing a tile that you step on and drops about an inch and then comes back up when you step off.
I have been researching and trying to find springs to use, but my cost is...
