Sounds a little hookie to me, it's torque arm just screws to the body of the car, if I was installing something like that I would want a sub frame almost like after market trailer hitches use, and I have to wonder how well it works for being as cheap as it is ($3,300), because you are basically getting two systems (two motors, two controllers) that run off a single battery pack, some of the good E-bike kits cost almost that much... so if this is real then making it fit a bike or motorcycle would be the next step.
I'll be interested in seeing if anyone has one at the
Mid West Renewable Energy Fair this year.
