Not sure that Boris is quite getting the point of these city bike schemes. He is talking about introducing to London a borrow-a-bike scheme similiar to the excellent Velib one in Paris and the one that has run for years in Copenhagen.
Bike racks are set up around the city with stacks from which anyone can borrow a bike for a short time, for a small cost, and then return to a different rack, somewhere else in the city.
The idea is to cut down on the need for car journeys and give people an alternative form of transport. Why then is Boris suggesting he will not position the borrow-a-bike racks near railway stations in London as they would be too popular?
Err, that is the point Boris.
