The first set of tags -- none of them fit, so I didn't choose one. Then when I created my bike pic, I saw it was listed as "fixed gear" and went back and checked -- well, you have to choose one of those. I chose road bike, but wondered if I should have chosen commuter or touring or something. Surprised they didn't offer hybrid.

After that, you make your own. But that first list, you're evidently required to choose one of them.

I'll add hybrid to my other tags though.
