Eric writes – “I have added an electric power assist onto a GT mountain bike. It is much more powerful than typical electric bikes. The basic motivation for this was to have a fun and efficient and environmentally friendly way to stay out my car for short trips around town, and also as a silent trail bike for exploring the hills. It can still be pedaled. When I first put this together it was even more of a blast to ride than I had envisioned. I have seen 70 year old people get on this bike and laugh like little kids – it’s like a magic hand is silently boosting you along. This website will describe the background of this little electric vehicle, some reflections on the electric and hybrid vehicle scene, and most of the details of motor and batteries should you be interested in making one yourself.” [via] – Link.
