In transport, many modes have been defined as “the most appropriate” or “the most efficient”. After many years of debate, academics and practitioners of sustainable urban transport have found that there is not a “most” sustainable, appropriate or efficient mode of transport, the truth is that what should be sustainable is the transport system, where various modes play a key role. Predominantly, public transport, walking and bicycles are the most favourable components of such a system. This brief article will discuss why bicycles are one of these modes.
