Letter Re: A 250 MPG Bicycle Gasoline Engine

Jim,
This is an unusual bike engine that uses standard gasoline (no oil mixing!) and delivers something in the neighborhood of 250 MPG, with a top speed of about 25 MPH. It might be just the thing to turn one's emergency bike into a viable vehicle, despite hills to climb. Although the tank will only hold about 23 miles worth of fuel, it'd be a simple matter to carry extra fuel to get one 50-to-100 miles. While probably not the perfect way to "bug out", it'd be nice to have motors like this on hand, "just in case". - Hawaiian K.
