The pollutants produced by a bike are infinitessimal compared to those spewing out the back of a car. However, you can go one step further and use Soy based lubricant instead of the usual chain oil. I don’t know whether it’s available in this country though. At present my bike gets by on no chain oil because I keep forgetting to clean and lube it.
