The thing we would like to explain to the aliens is how humans ride a bicycle. We mainly use two forms which are pictures and videos to help them comprehend.

For the picture part

First, we would like to draw the bicycle image. We first want to draw the separated parts of a bicycle. The brick, the saddle, the front wheel, the back wheel, and the pedals are the five parts we draw separately which are also the most important compositions of a bike. Then, we draw a complete bicycle shape to show how these compositions connect to be a vehicle. Since the image is a plane, we will then draw bicycles from several different angles to let them better understand what a three-dimensional bicycle looks like.

Second, we draw a human body to let them know what humans look like.

Third, after we use images to explain the structures and appearances of both a bicycle and a human body, we draw steps of how a person gets on the bike and starts riding. We use different images to draw different steps. The first step is the person holds the handlebars of the bicycle, and the second, the person straddled the bicycle seat. Then, the person puts his/her feet on the pedals. The three steps are something a person needs to do before bike riding.

Then we draw an overall picture of a person riding a bike, we use some signals to show the movement.

The picture can show the detailed compositions of a bicycle and a human body, and how they connect and cooperate to move from one place to another. But to better and vividly understand how the time flows and the bicycle moves, we would like to then provide a video.

For the video part

We plan to provide a bike riding tutorial video that we found on the internet. In this video, a person is first showing the different compositions of the bicycle; then he gets on the bike and starts to ride. He rode slowly for some distance so that the aliens can better comprehend how the whole process of riding a bike is. With the form of a video, where each step has its own strict order, and time shows in a linear way, aliens can better understand the movement of time.

By combining the images with the video, the aliens could understand the structure of the bicycle and its effect on people well, as well as the movement of time implied in it.
