The bearings don't need friction, but everything else does. It there wasn't any friction it'd be impossible to bolt anything together.

How friction influenced the invention of the bicycle?

Tires, grips, pedals and brakes needs to have high friction, while all rotating parts needs to have low friction.


What do we use in bicycle wheels to reduce friction?

We use ball bearings in bicycle wheels to reduce friction. Ball bearings are small, metal balls that are placed in between the moving parts of the wheel hub to help it spin smoothly and with minimal resistance. This helps improve the overall efficiency and performance of the bicycle.


Why does oil make a bicycle work better?

Oil can reduce friction between moving parts, and protect exposed metals from rust.

What part of a bicycle is a useful friction?

The brakes! And the tires (no friction = no traction).


Where on a bicycle is friction not important?

In the bearings, where you want as little friction as possible.


Is a bicycle rolling down a hill friction?

Yes, as the bicycle rolls down the hill, there is still some friction present between the wheels and the surface of the hill. This friction helps to slow down the bicycle's descent and eventually bring it to a stop.


Why is friction called a necessary evil?

Friction is necessary : If there is no friction between any two surfaces in contact, then the present day civilization will be no more- as we cannot even walk properly on the earth. There will be no fabrics and garments, no construction of buildings and no furniture, even no cooking and no vehicles. So friction is necessary. But too much friction causes a heavy loss of energy, wear and tear of machinery. Thus, the efficiency of machines will decrease tremendously. So, it is rightly said that friction is a necessary evil.


What are the benefits of using lithium grease on a bicycle?

Lithium grease helps reduce friction, protects against corrosion, and provides long-lasting lubrication for bicycle components, resulting in smoother operation and extended lifespan of parts.


How does bicycle friction affect the overall performance and efficiency of a bicycle?

Bicycle friction can impact the overall performance and efficiency of a bicycle by causing resistance that makes it harder to pedal. This can result in decreased speed, increased energy expenditure, and reduced overall efficiency.Reducing friction through proper maintenance and lubrication can help improve performance and efficiency.
