#9 GreasyPant’s 50-MPH electric bike

Greasypants not only built a clean looking Crystalyte hub motor powered 50-MPH bike and documented it on youtube, but he also created a book on how to build such a bike. He sells his book on the web for $50. For the last few years he has had a great presence on google searches, and has managed to make himself a few dollars while spreading the word on how to build an electric bike.
