You have to replace the gas?
I seem to forget that it eventually runs out. Its only 7 miles to work for me. It takes a while for me to burn a tank of gas. I have actually run out before and it took a minute to realize that that was what happened. Turn on the reserve and away I go!!
I can drive to work and back, to the store and just around the neighborhood for what it costs to drive to work and home again with my truck. (Dodge ram V8 at best 14mpg in town)
around 100mpg compaired to 14 mpg. Its a big differance.
I guess i loose a little towing capacity with the moped but it does seem to be able to tow my but around....
