No 8 Free Bikes.

Initially set up in Amsterdam, but now in a handful of other cities like Paris, and Brussels - Europian countries are welcoming the notion of free bikes. The idea is that people sign up to the scheme and can then borrow bikes for free all around the city.

This idea could definitely work in London... the scheme has been proven in other smaller cities. Advertising on the bikes would be a good way of funding the project. I think the project would promote itself when implemented. Millions of tourists would be more than happy to ride the streets over getting the tube. Westminster and Mayor of London would have to back the project to make it a complete success.
