Daughter: What's this , dad?

Dad: It's a bike from early times.

Daughter: A bicycle? Where are the handles bars?

Dad: It doesn't have handlebars and its peddles are on the big front wheel.

Daughter: Does it have brakes?

Dad: Yes, it does. The brake is on the back tire and you can also stop the bike with peddles. But if you use the brake you could fall off the bike.

Daughter : Wow, that's dangerous. You must be careful.
