Bike gears work like levers. A set amount of effort can be turned into either a long and weak motion, or a short and strong motion.

Imagine opening a door by pushing either close to the hinges or close to the lock.

A short push by the hinge will make the door move a big distance, but you have to push hard

While if you push by the edge it'll be easy, but the door will only move a short distance.

What is the purpose of the bike front cassette and how does it affect the overall performance of the bicycle?

The bike front cassette is a set of chainrings that help to change the gear ratio of the bicycle. By shifting between different chainrings, the rider can adjust the resistance and speed of pedaling. This affects the overall performance of the bicycle by allowing the rider to efficiently tackle different terrains and riding conditions.


How does a front derailleur work to shift gears on a bicycle?

A front derailleur on a bicycle shifts gears by moving the chain between different chainrings. When the rider operates the shifter, the front derailleur pushes or pulls the chain onto a different chainring, changing the gear ratio and allowing for easier or harder pedaling.


How does the shifting mechanism on a bicycle work to change gears while riding?

The shifting mechanism on a bicycle works by moving the chain between different sized gears on the front and rear wheels. This changes the resistance and speed of pedaling, allowing the rider to adjust for different terrain or riding conditions while in motion.
