This is a video of my propane powered bike. I chose propane as the fuel for several reasons. First i didn't want to deal with having to charge a battery on an electric bike. Also, I didn't want to deal with the yearly maintenance of a gas powered bike. I have enough of that with my lawn mower and snow blower. Propane gave me many benefits. It runs on the 1lb propane tanks which makes it easy for me to carry additional fuel. I refill my 1lb bottles from a 20lb propane tank, so I am not wasting the empty tanks. The end of year maintenance is as simple as disconnecting the propane tank and running the engine until its out of gas. This usually takes about 15 seconds. To prepare it for use after storage is check the oil and attach the propane tank. I have had this for 3 seasons now with no problems. I love this little work horse. I bought most of the parts need to build this from "Staton-inc". They were a great company and helped me with many of my questions. The whole build took me 1 weekend and then a little bit of tweaking the following weekend. I am entering this in the Bike Contest, so please vote if you like it.
