I got into bicycle motors a bit recently.

At one point I ran some figures comparing gasoline and electric setups;
of the two (popular products) I compared, the electric cost over twice
as much and had a cost-per-mile that was five to ten times as high as
the gasoline engine setup. This was using U.S. fuel prices, Europe is
2-3X as high but still you can see the problem.

Advocates of electrics play yup the low-pollution aspects but that is
very debatable over the long term, considering the battery production
and disposal requirements.

There are a few situations where gasoline engines aren't practical--such
as when you desire silent operation, or for a physically-disabled rider
who wants "pushbutton power",,, but judged on a cost basis alone,
electrics still lose badly.
