I am wondering if anyone has ever tried to get extremely high mpg out of their bikes. I know I got about 125 mpg on my Titan kit on one tank. I think 500 mpg is potentially attainable, although at slow speeds.
We are already set up with the right size motors for supermileage competitions.
The most important thing is that to get high mpg numbers, you need to pulse the motor to accelerate up to speed, then coast with the motor off as long as possible before pulsing again. So low friction coasting is very important.
Aerodynamics is also important. But at slow speeds you should be able to get very high mpg numbers with just a bike.
One thing that might be difficult is to figure out how pedaling affects mpg numbers. If I pedal 100% of the time, I get infinite mpg. If I pedal to start out, I improve my mpg by quite a bit, because the start takes a lot of power. If I lightly pedal while at speed, just adding a little extra power, I can still make a big difference in performance of the engine.
So for practical use, it is OK to use pedaling techniques, but for competition and comparison it is difficult to regulate how much pedaling the competitors can do. The more the better as far as I am concerned but then competitive people will just pedal all the time and not use the motor.
How would you set up a supermileage competition for motorized bikes? What rules would you make about pedaling? How would you set up the bike?
