I have a GE 9" Series Motor with a built in adaptor for converting your VW Bug or Bus. This motor was original to the Bradley GT E VW. I have a Synkromotive controller as well. Both together $1800. It is an excellent package deal and an excellent motor and controller.
Controller: 156 volts and 750 amps. Fully configurable to your needs. Check the specs. This controller has about 500 miles on the controller and considered NEW.

I am located in Northern California and if your thinking of converting a VW Bug this will work perfectly for you. No cutting and you get a motor that is more powerful than the Warp9 Impulse or Warp9. Larger than the weenie 8" motors. You can’t go wrong with this setup.
