Thanks, 大枪 ! I had a friend who was helping me get a bike off of Taobao, which probably is the best way to do it (cheap, many choices), but I am too impatient!
The taxi driver didn't know the address for Oyama, so I went to Merida.
I now have a decent road bike and accessories

The bike was about 2400 kuai. They actually didn't have the one I wanted, so the girl ran to another branch to get it for me. They were very nice and helpful!
I will probably also get a cheapie bike, just for commuting short distances. I'm thinking rusty and pink colored...
