I have been biking and riding the bus for the last 2 years. I bought and electric hub motor but battery life up hill with SLA`s doesn`t get you far and pulling around and extra 45LBS doesn`t sit well ( I was riding up a slight grade for eleven miles and usually into a head wind). Electric works well for short trips and until battery tech becomes more affordable few are going to shell out close to $1,500 for a set of poly batteries. So the electric motor went to my son`s bike and I just use it for short trips. I bought a 4-stroke engine kit and have well over 1,500 miles on it with no problems. I went with a 4-stroke over 2-stroke because you can fill up at any gas station and don`t need to pre-mix your fuel also the torque characteristics of a 4-stroke are stronger. I now sell these kits and build motorized bicycles. What I want to do is make these machines more user friendly as I write this you need to have some mechanical knowledge to install one on a bike. Support is almost nonexistent, my plan is to setup shops that build and maintain these bikes.
Gas millage is between 130 and 150 MPG with speeds between 30 to 35 MPH. Alcohol is another fuel option that I will experiment with in the future, diesel engines would be nice but I think weight will be prohibitive, possible a recumbent trike may work. Hybrids have and weight issue but there is a super capacitor that may be available in the next few years and could work to make electrics have greater range. The advantage with motorized bikes is most states don`t require license, registration or insurance these alone would pay for a bike in a year, take into consideration the rising cost of gas and some could pay for a motorized bike in a month.
