"Little Red Bike", Hangzhou public bicycle, is the model of urban green travel, and wins the widespread praise from citizens and tourists after 16 years of continuous optimization.

Hangzhou rolls out multiple moves so that citizens are more willing to choose green travel. For example, the cycling experience is improved by upgrading tires, seat cushions, bicycle baskets, pedal plates, etc.; the free rental service within one hour is implemented, saving about 1,351 million yuan in travel costs for citizens and tourists; the 24-hour service and "self-service borrowing & returning" are carried out, solving the problem of difficulty in returning bicycles.

As of the end of October, 2024, Hangzhou set up 5,690 service points with 157,700 bicycles. This is the largest urban public bicycle project in the world, and the maximum daily number of rented bicycles is up to 473,000 person-times.
