Google directions are the second best navigation experience I had here in Germany for cycling. Close behind OSM (probably because they take data from OSM without saying so...).
Cycle ways are also quite well documented here. It shouldn't be an issue at all. Especially in such a big city. They even use OSM data officially.
My guess is: they just don't care because the market is not good enough and most of their customers are happy with car navigation. According to the wiki page [+] they have cycling maps in China which is ridiculous if you consider the bike infrastructure in Germany. It isn't if you consider the market.
