Trailer bike

A trailer bike is a special kind of bike that helps you ride with an adult. It's like a regular bike, but it has one extra wheel at the back. This extra wheel has pedals that you can use to help pedal the bike with the grown-up.

When you want to go for a bike ride with someone who's bigger and stronger than you, you can use a trailer bike to help you keep up. You can sit on the seat and use the pedals to help pedal the bike forward. You don't have to worry about steering or stopping the bike, because the grown-up is in control of that.

The good thing about a trailer bike is that you can still get exercise while riding with an adult. You can help pedal when you want to, but when you get tired or need a break, you can just stop pedaling and let the grown-up do all the work. It's a fun way to ride a bike and spend time with someone you love.
