China's first unattended bike depository opened for business at Tianjin University of Technology and Education on April 16. The depository is an 8-meter-high cylindrical steel structure with a diameter of 8 meters. A total of 120 bikes can be deposited in the structure, though their rims must be between 20 and 26 inches across in order to be accommodated. The depository is equipped with an ID card reader to ensure safe and speedy service.
