The latest call to extend the scheme has comes from Wandsworth. Cycle hire has only recently been introduced in the borough, but is already a success. Extending south would make sense.
As already reported on this blog, Southwark Council have agreed to their slice of the funding of Boris bikes in that borough. Even more than Wandsworth - Peckham, Bermondsey, Rotherhithe, Walworth and Camberwell need the bikes.
Usage seems to be up now that the winter is over, and new cycle routes, like the Quietways, are planned. TfL should use this momentum to announce the next phase of expansion of cycle hire. With a new sponsor to replace Barclays maybe?
In other news: expansion of Dublin bikes is planned. And Storey's Gate docking station has opened, bringing Boris bikes closer to St James's Park.
