Cycles save energy - they don't use fossil fuels or any other fuel, except human energy. Cycling is a good exercise too. It builds up your energy. But these cycles belong to people who use them for travelling to their workplaces every day and back home. And then once a week they come to a place of worship riding the same cycles. Even if the religious service is in the dead of the night, after their whole day's tiresome work. Were the cyclists building up their muscles/energy? Cycles are toys for some!
