[ausev] Electric Arial Atom is a fixed gear.... Intresting.

[Ian Ward]

They are using AC Propulsion's AC-150 drive, which is up there in my list of
dream drives.  But at $25K, it is out of most people's price range.

As I mentioned before, Jeff Thomas of EV Bones is working on his personal
kit car project and it is also using an AC-150 with A123 cells. He is using
a Honda Si 5sp transmission with a custom 1st gear set at 9.65 to 1 with all
other gears removed.
