They absolutely have gone through a technological revolution. The deal is you are to young. they have been around for a while now.
Bicycle;
petals, all metal construction after wood, rubber tires, spokes, gigantic front wheel, three wheels, back to two wheels, ingo propulsion,gears, suspension, mud flaps, inner tube, brakes, a seat, speeds to the gears, aluminum construction, carbon frame construction
Im sure if you research umbrellas, you'd find a huge difference between the parasols of 100 years ago, and the gadgets you can buy today for a few bucks.

First thing, Bicycles have gone through technological developments. That's why we remove the pedal and fix a motor to make it faster and easier to travel.
Assume you are holding an umbrella in rain . Would you ever think "How can i develop this umbrella to go without getting wetting me ?". I don't think so. We only think "how can we go without getting wet" using some other way.
The main reason is you can change the bicycle as you want because it is a technological thing. But you can't change rain because its natural thing.

They are simple machines. but have underwent evolution
Just check out the Tour De France. Bicycles raced in the Tour De France are designed to be aerodynamic, lightweight, sturdy, and ergonomic. They have efficient derailleurs that transfer and multiply pedal power. Though it doesn't look like it bicycles are more complex than they were in 1880s when penny farthings were rolling about.

umbrellas do the job, and there is no need for them to be any more easier to use. do you want them to open when you say "open!"? and bikes, they are going through technological evolution, maybe you just have not seen it. and for cell phones, almost everyone has one, which means everyone has different needs, and thats why the companies are making different phones for different people

It would be kind of like re-inventing the wheel. While there have been some improvements on these items the basic function remains the same. Cell phone function has changed to include new purpose such as photography, media and web access. So evolution of items comes down to function and purpose.

Because they're pretty much good at what they do right now. Electronics (and such) change with time to make them better and faster. Bikes and umbrellas are 2 ideas that can't be improved upon much.
The bike has changed. Its made with sturdier alloys and better tires than it once was.
The umbrella has changed. Its made with sturdier materials like metal instead of things like wood.

They do. My umbrella today has flaps that let the air through so that it doesn't turn inside out. It has a velcro strap to hold it shut. It has a button to automatically open and close it.

My umbrella is perfect. It was designed for a specific function, and it carries out that function admirably. Please share my umbrella.
