A picture is worth: Steven M. Johnson's GYM

Just last week I was rolling about Durham, North Carolina in an ELF, which was as close to a pedal powered car as you can probably get; turns out Steven M. Johnson figured this out years ago. Given how hard it was to push the 150 pounds of ELF without a bit of electric boost, I suspect that the GYM driver is not moving either fast or far.
