A bicycle cooperative is like a clubhouse, but instead of having video games and toys, they have bikes and bike tools. When you go to a bicycle cooperative, you learn how to take care of your bike with the help of grown-ups who know a lot about bikes. They teach you how to fix your bike so you can ride it again, and they also help you to learn how to ride safely.
At the bicycle cooperative, you might see all kinds of bikes, from big ones to small ones, and from new ones to old ones. Some bikes might look like they've been riding for a long, long time, but that's because the people at the cooperative care about them and fix them up so they can still be used.
Sometimes, you might even get to build your own bicycle at a bicycle cooperative! You can choose the colors you want and put the pieces together with the help of the grown-ups. It's like building a puzzle, but instead of it being made of cardboard, it's a real bike that you can use to ride around with your friends.
When you visit a bicycle cooperative, they'll teach you how to be a kind and helpful member of the club. They teach you to be respectful of everyone's bikes and tools, and to always ask for help if you need it. That way, everyone can have fun and learn how to ride their bikes safely and happily.
