It's a pleasure to hear the different points of view on drivers for getting involved in building motorized bicycles.

For me, I like the economics and the environmental benefits. I do endurance bicycling (no engine) as a sport and thought that I'd like to use a bike for more that working out, but did not want to get sweaty in the process (like going to the store or other errands). I looked at scooters (small ones) but the cost put me off (registration, insurance, etc.). Here in california, I believe that a motor assisted bicycle requires one to be 16 yo and to wear a helmet...that's it. Simplicity is sweet. The added benefit is >100 mpg. The equation works. (Plus I like to tinker...)
