Don't forget to buy bicycle lights, which shine well in the dark, because you will need them. Personally, when I bought my bike so I could drive from university to work and from there to home, I bought strong and rechargeable lights from https://www.amazon.com/Vont-Rechargeable-Illumination-Resistant-Accessories/dp/B078TB9TMK because I knew it was something very necessary and useful. It was so convenient to ride a bike that I didn't even need a car. It is much healthier and more interested.
