Cycling is not carbon neutral and does cause an environmental impact. Bicycles need to be made and in many cases they or the materials from which they are made are transported around the globe. Tyres and inner tubes are consumables. Cyclists need to eat more than if they were inactive and frequently consume carbohydrate rich foods which need to be transported.
To be truly environmentally useful, one should dig a large hole with one's bare hands (no spades) and bury oneself.
