Would you rent a bike to add to your BMW ( Bus/Metro/Walk ) commute?

Say you are already minimizing using your car by commuting more using buses, the Metro and walking, would you add bike renting to your routine and why would you? If enough bikes for rent are made available in almost every corner of your area would you use them and if not, what’s your reason? Bike rentals are being offered in some places in countries like the US, mostly in cities. Do you think this trend have potential for growth?
