How to Draw a Bike

I decided to try my hand at drawing a bike. Here is how to draw a bike.

Paper

Pencil

Compass (I don't really know the name; please let me know if you know what the actual name is)

Marker (Optional)

Here is my first drawing of a bike without a bike to look at for reference. (It's pretty terrible)

This is my next drawing with a bike for reference. I will try to explain how to draw it.

1. I used the compass thingy to draw both wheels

2. I started to draw the basic frame without really caring about the thickness

3. Now I started to make the thicknesses bigger or smaller, depending on what was required

4. Lastly, I touched everything up making it look how it is

I am probably going to add some more pictures to this or more steps, but I was unable to do it in the first place because of the time crunch for this contest. Also, if you have any tips or things that you want to tell me, please let me know!
