Unless you have a "fixie" there's a small one-way clutch hidden in the rear hub. This clutch engages when the pedals are being pushed in the right direction, but will allow the bike to "freewheel", or "coast" when the power is coming from the other direction.
when you pedal, they go round?!?
The bicycle gear ratio is important because it determines how easily you can pedal and how fast you can go. A higher gear ratio means you can go faster but it's harder to pedal, while a lower gear ratio makes it easier to pedal but you go slower. Finding the right gear ratio can improve your efficiency and performance when riding a bicycle.

One can find a foot pedal for Trek bicycle at Trek Bicycle Superstore. Trek Bicycle Superstore has five locations in California and one location in New Mexico. There is nothing that special about a Trek. You can buy replacement pedals just about anywhere. They'll have to have the right thread though, which for a TREK is most likely to be 9/16".
A. only when you sit on the haldlebars and pedal ;-D A Unless it's a custom bike, or a bike with a real improbable fault, they don't.
The gearing ratio in a bicycle is important because it determines how easily the rider can pedal and how fast they can go. A higher gearing ratio means the bike is harder to pedal but can go faster, while a lower gearing ratio makes it easier to pedal but slower. The right gearing ratio can improve the bike's performance and efficiency by allowing the rider to maintain an optimal pedaling cadence for different terrains and speeds.
Honey, Kirkpatrick Macmillan was too busy inventing the bicycle in the 19th century to worry about college. College? Please, he was out there revolutionizing transportation while you were still in diapers. So, no, he did not go to college, but he did pedal his way into history books.
Asssuming it's not locked, broken or anything it'll move forward when you put pressure on a pedal that is pointing forward.
The pedal in the car you push to go faster is the accelerator pedal.
The bicycle squeaked. I've had a brand new bicycle for my birthday. I go to school on my bicycle.
To make sharp turns on a bicycle, lean your body and the bike in the direction you want to turn, while also steering the handlebars in that direction. Shift your weight to the outside pedal and look where you want to go. Practice these techniques in a safe area to improve your skills.
