Looking at the Urba Electric design, three Controller designs are mentioned-

1) a modern controller
2) a Voltage Stepper-not as efficient but probably cheaper
3) a CVT transmission to keep the motor at most efficient RPM (possibly with a simple Amp limiter-no details on the page)

I don't have a copy of the plans yet(I plead Extreme Poverty at the moment) but i'm really curious on what effect a current CVT (either mechanical or electronic controlled) would have on a light EV...
From looking at whats posted across the web, I would not even consider purchasing the plans. Everyone said the chasis was too weak looking and it's basically nothing more than an electric golf cart with add ons!
Modding a small car will be a lot more interesting than trying to completely build one
I always did want to play around with this stuff, now I have a chance to do so
