The bikes are green and green, and so is the sponsor

Bike sharing systems have popped up in over 500 cities around the world. (Vancouver is still waiting, but evidently 2015 is when the city will roll out a network of bikes available for short term hire. British Columbia's mandatory helmet law for cyclists remains somewhat of a a stumbling block.)

In Toronto the system is sponsored by the TD Bank. So a green transport system, bicycles, is identified by the colour green and is sponsored by a bank also associated with the colour green. (The TD Bank refers to each of its its ATM machine as a "Green Machine".)

All told a pretty good piece of sponsorship and branding.
