Check out this great video below on hangzhou's bike share program. Why do I love it?
2 main reasons:
1. Some of the bikes have built-in seats for children!
2. There is a multi-modal connection btw the bikes and buses--if you ride the bus first you get 90 minutes of free biking! (I love multi-modalities. It would be so great if there was synergy btw buses/subway, zipcar and capital bikeshare in DC--the same card for all and/or discounts to encourage use!)
