re: Greenline EB-8624 purchase

I'm looking for an ebike and have all but settled on a Greenline EB-8624. Best price so far is US$838 delivered to NJ from jazzygearsports.com

Anyone have familiarity with this Bike,Manufacturer or seller? I want to use it to commute 2 1/2 miles so it should be powerful enough to move my 5'6", 150# self up a pretty steep local hill.

Frankly, the battery discussions on this and other forums have me bewildered.

Any input would be appreciated,

thanks,
