>>4081717/c/ is for sharing images, and the OP is expected to be the main contributor, at least at the start. Typically you make a thread and then post around 6 images for it. Girls with bikes is a perfectly valid thread topic, we've had them before.
For /c/, and every other board, it's always best to observe other threads for a while to see how the community works before engaging in the community yourself. This helps keep a high quality of posting.
Also, don't use a name unless you have to. You'll learn when the appropriate times are by learning how the board works.
