I spoke with a representative of Polaris who sent me this brochure of the Polaris Vector V2 which should be available in April 2014. I'm very impressed with the specs but not sure I can wait as I have a couple of trips planned before April. I'm also a little concerned about the 6ah battery. It is 48 V and they do have electric braking and a regenerative mode which may help but I'm not sure if it will carry my 185 lbs up the 12% grade to my house after a ride. The brochure also doesn't say anything about the DuoDrive so I don't know if that's a feature in the new model.
