London Cycle Stations Map
On the 30th July London is launching a Cycle Hire scheme. Under the scheme people will be able to hire bikes from 400 docking stations situated throughout the capital.
Transport for London are preparing a Google Map showing the location of the 400 docking stations. TfL say the map will go live on the 30th July (at the moment the map is empty). If you can't wait until then check out the map I created for this Fusion Tables tutorial.
The only other map I'm aware of is the planned Cycle Hire App for the iPhone. The app will use OpenStreetMaps when it launches.
