[London, July 30: A woman enjoys the new bike-rental system. It is hoped that the flagship cycling scheme will help build on the growth in cycle journeys taken on London's major roads. Image via Getty.]
So my college tried to do this my freshman year, at University of Rhode Island and let me tell you that it didn't last very long. After a week or so bikes ended up in the pond and stolen etc. And that was only on a campus, not a city.
So good luck with that London.
