I like the idea better than races but don't really like timed riding or events but instead like the unracer meme of going out to "just ride"

sheldon brown's site has some articles for beginners and for repairs, I feel like a basic maintenance article should be there somewhere or on a search engine: https://www.sheldonbrown.com/beginners.html

the scope of "basic" to me feels like it expands at times, but if you read around you can probably find different ideas
