It takes enormous concidence for bicycles to succeed to the extend they do in e.g. Dutch cities, or Copenhagen. It takes flatish land, infrastructure, mentality, achieving certain critical mass. In many places bicycle is used as a status symbol the same as a car ie. people drive their super sport carbon bicycle during days off, while during work days prefer to be stuck in traffic in their expensive car. Walking only will never be feasible in any largish city. Metro system is an order of magnitude more complex, only low hundreds of cities globally can afford it.
