Bike-to-work day is a special day where people are encouraged to ride their bicycles to work instead of using a car, bus or train. The day aims to promote sustainable transportation and to get people to exercise while they commute.
Let's imagine that you have a bicycle that you really like to ride. One day, your mom or dad tells you that it's bike-to-work day, and that means you get to ride your bike to the place where they work instead of going in a car or bus.
When you ride your bike instead of being driven in another vehicle, you can help the environment by reducing air pollution and traffic congestion. You can also feel good knowing that you're getting some exercise and staying healthy.
It's important to wear a helmet to keep your head safe while you ride, and to follow the rules of the road (just like when you're walking or crossing the street) to stay safe.
So, on bike-to-work day, you get to ride your bike to where mom or dad works, help the environment, get exercise, and have fun!
