# How Does A Bike Move Forward

### It helps to lean forward or even stand up when you re going uphill so you can apply maximum force to the pedals and keep your balance.

How does a bike move forward. If we assume that the bicycle is moving at constant velocity no acceleration then the force f 4 must equal the resisting forces opposing the bicycle s motion. The tire pushes backwards against the road surface by means of friction. There is a chain that is conected to a gear on the sprocket and to a gear on the back tire. These resisting forces are gravity rolling resistance air drag and internal bicycle friction.

Other people will tell you all kinds of things about balancing on the bike it s a rule that happens to work with their bike fit but the fundamental thing is this get the thigh spine position correct then you can work out the body rotation which then dictates the seat position relative to the bb the handle bars relative to the seat bb. I occasionally get questions like bike doesn t move when i pedal help my wheel doesn t move when i move the pedals. The only way to get your bicycle to move forward is to use your feet to push the pedals. The force f 4 is what propels the bicycle forward.

Dynamics falls under a branch of physics known as classical mechanics bike motions of interest include balancing steering braking accelerating suspension activation and vibration the study of these motions began in the late 19th century and. The road cannot move so the force causes the bicycle to move forward an equal and opposite reaction. If you watch the process of moving parts while the pedals are moving you will find that it all works smoothly together. The wheel transmits the force to the tire the same way.

For the moment let s put aside the the geometry of a bicycle with the angle of the steering column and the trailing distance of the contact patch behind where the steering column proj. A short and sweet answer of force doesn t help you understand what is going on does it. The bicycle s inverted a frame is an incredibly strong structure that helps to distribute your weight between the front and back wheels. When you peddal it moves the chain and the back tire spins which pushes the bike along.

What s wrong pedaling won t move the tires or pedals chain.
