From
the map it seems there are 2 other stations 2 blocks from there, which you may not have been aware of. This brings up my concern again that it's hard to spot a station that may be only 1 or 2 blocks from where you are. I strongly suggest them to post the complete map of all stations at each station (like what is done at bus stops). At least post the addresses of nearby stations.
That doesn't mean there were bikes at those stations either. What I find is that at rush hour there are never any bikes around midtown. Mid-day you can find them.
