Organisations of cyclists and cycling enthusiasts have written to Calcutta’s police commissioner on Tuesday with an appeal to allow bicycles to ply on all roads in the city. The organisations have said a growing number of people, many of them poor, are cycling to work to avoid crowded public transport amid the Covid-19 pandemic. The letter also said the city’s transport system should gradually start giving more space to cycles as they do not pollute the air. Given the annual phenomenon of poor air quality in Calcutta during winter, reducing tailpipe emission is necessary and that can be achieved by switching to green transport like cycle.
