The whole world is panicked with COVID-19. It has brought about a change in the way we lead our life. We all are worried about the 'new normal' situation of the post-pandemic world and seeking for the answer of how will be the post-pandemic look like? As the COVID-19 is a contagious disease it can be spread from one place to another via a different type of vector. To ensure safety of the mass population we must keep social distance and avoid crowded mass transits. After lifting lockdown, there will be a crisis of transport as the mass people try to avoid public transport to keep social distance. Though some people shall use their private cars to escape crowds most of the people have no safe transport system. It will be a curse in the post-COVID-19 era. A return to the mass use of private vehicles will not allow governments to meet their sustainable development objectives. Due to the COVID-19, public transport usage has fallen significantly as an increasing number of people choose to walk or ride bicycles to avoid crowded mass transits and follow DGHS's advice for physical distancing. For this reason, there will be a need for alternative, safe, greener, healthy and sustainable transport systems; Bicycle can be a solution to this problem. According to the United Nations Environment Programme (UNEP), investing in pedestrians and cyclists - who often make up the majority of citizens in a city - can save lives, help protect the environment and support poverty reduction. Bicycle is an affordable, reliable and sustainable means of transportation, it fosters environmental stewardship and good health, providing a cost-effective form of transport while reducing the risk of heart disease, stroke, certain cancers, diabetes, and even death, according to the World Health Organization. Safe infrastructure for walking and cycling is also a pathway for achieving greater health equity. Cycling is a means for increasing physical activity and becoming physically is the prerequisite for good health.
