What´s The Giver A Dystopia?

The book The Giver is a dystopia. It is a dystopia because you get your bike at 12 years old, they kill small children, and they can’t leave the community.
Children in The Giver receive their bikes when they are twelve. I think that is too old.I think you need to get your bike it eight years old.Because if you get your bike at 8 you can practice. So when you get twelve you will know how to ride your bike to where you need to go. So you need to get your bike taller than twelve.
In the b community you have to snake out. When John's smoked out with the other twine planes you're trying to find tham and they were having to hide just because they didn't like the community and so the other twine wouldn't get killed. They should not have to snaked
