And you are gonna need to have all of the above installed.

You will either:
- Pay to have someone install them
- Buy the tools and do it yourself
- Borrow tools from a friend

Some bike tools are generic like a 15mm wrenches and allen wrenches. Then there are more specific tools like crank arm pullers, chain breakers, spanners. cone wrenches, chain whips, etc... Each of which costs at least $10 and go up from there.

Then you have to spend the time learning how to use them properly. Yeah, it's cool to know how to work on your bike. I, as well as many here on the forum, do. But some people don't care and just want to ride. Nothing wrong with that. But, the rhetorical question is: which kind of person are you?

You have a bike stand in the photo, so maybe you are already familiar with building and maintaining bikes.
