There were three four things that I paid for when I bought the bike.
The bike itself was 20800yuan and tax was about 1500.
The insurance and registration worked out to be about 2000.

I thought it was a good deal. They did try to charge me about 30,000 the first time I went in there but I just showed them the listing for it on taobao and they quickly agreed to this price. You can also do a search for the bike in chinese and find that this is the factory recommended price.
