The alliance was formed in November when mayors from Inner West, City of Sydney, Randwick, Waverley, Woollahra and Canada Bay councils met to draft a set of guidelines to address the problem of haphazard placement of share bikes in parks and streets.

Inner West Council mayor Darcy Byrne, who convened the meeting, said it was important that one set of rules was established to protect pedestrian safety and ensure the success of bike share schemes.
