Bottle cage

A bottle cage is something that holds a water bottle on a bike. It's like a little basket that you put the bottle in so you can take a drink while you ride. Just like how you have a cup holder in the car for your drink, a bottle cage is the same thing, but for your bicycle. The cage is attached to the frame of the bike and it keeps the bottle from falling out while you're riding. It's important to have a bottle cage so you can stay hydrated while you're going on your bike adventure!
