In 2001 Mary Jane Ortega, then mayor of San Fernando City in the Philippines, knew her city was choking to death. The cause? Air pollution, specifically that from two- and three-wheeled vehicles powered by dirty two-stroke engines, including motorcycles, scooters, and the motorized rickshaws known as tuk-tuks.

Around the world, outdoor air pollution kills 800,000 people a year and sickens many more. While big vehicles like Hummers and other SUVs are often blamed for excessive emissions, some of the worst culprits are the smallest rides around…

…larger but much more efficient auto­mobiles…use four-stroke engines…two-stroke vehicles spew great volumes of dangerous hydrocarbons, carbon monoxide, and smoke. A single two-stroke engine produces pollution equivalent to that of 30 to 50 four-stroke automobiles…

    You should check out my friend, in Boulder, who is building electric-motorized bicycles out of production bicycle frames: he has a Specialized Stump Jumper convert and a recumbent convert. His name is John English, works with a small mechanical engineering studio: Boulder Engineering Studio:

  2. Hmmm…a bit more technical info would be useful here.
    What is it about two stroke engines that cause them to be so polluting, thus making that smiling green dude up there such an unknowing ass?

  3. I wanted to be a professional biker but unfortunately budget and responsibility factor did not let me do that. But now i want to be a racer let see what happens now.
