Patterns and Forces
When I chose bicycle gears as my object of study, it found them pretty straightforward at the start. That's where it starts, the transition from finding something simple to exploring the smallest of the complex things that make them whole. So come along, with some sketches and annotations let me show you how bicycle gears work.

Gear Mechanism
The chain of the cycle sits on two gear mechanism, one at the front and rear. When you pedal, the chain moves on these gears and you are riding the cycle.

Do we need bicycle gears?
Let's you're riding a bicycle on a normal road. Suddenly, you can see a slope approaching towards you. Now as the descent starts you find yourself applying a stronger force to pedal the cycle. It becomes even harder as the height increases. Finally, you've made it and you feel exhausted.
Let's just say all of this could be avoided.
You just need additional gears in your cycle. Gears are nothing but axles on which the chain rotates.
They let you control the power you have apply to pedal the cycle.
So pedal as hard or light you want, it's all under your control.
So the next time you ride up an ascent, you will be doing it with ease.
The chain rests on the first gear, where pedalling feels effortless. Remember this while going up that slope.
The chain sits on the seventh or the last gear. The power needed to pedal now is significantly higher.
The gear system is seperated for better understanding. The box thing with two wheels attached to it, is the Rear Derailleur.

Rear Derailleur
the prime component of the gear mechanism. It has a set of springs and jockey wheels that adapt and re-dock the chain when you change the gears.
It makes the gear system of the bicycle a possibility.
