I think one thing I learned that I wish I knew as a beginner is there are lots of different types of riding and lots of different types of bikes that go with it.

Hybrids are great for quite a few of those types but not optimal for all of them.

My advice would be try to spend as little as possible on accessories, gear, clothes, bikes etc until you know a little more about what kind of biking you want to spend your money on.
