For TreeHuggers interested in assisted bikes but finding the battery powered electric units don't have quite the zing you are looking for: Robert Maddox of Medford, Oregon is selling a rocket powered bicycle on eBay. It has absolutely none of the benefits of a regular bike, spitting out 140 decibels of noise and consuming a lot of kerosene, but goes like a bat out of hell. I suspect that the cars and pedestrians will get out of the way when they see this baby coming. Buy it on ::EBAY or watch the video of it in action below the fold. via ::Geekologie
It is not a new idea; we showed one from quite a few years ago.
