Nov 2009. Riding season is over. Put @350 miles on bike since May. Great first season! Kept my sanity afloat during tough $ times this summer. Wanted to get upgrade to 72V (55Ahr batteries) but couldn't get the $ together.
Sept. 2015 update. I failed to mention that in Sept. 2009 I unveiled the Sparkster at the Harley Museum in Milwaukee, my residence at the time and was initially denied access by the event gatekeepers. Luckily I had preregistered and was allowed to pass through. Interesting that H-D never contacted me but unveiled their EV Harley in @ 2012/13.
I surmise that I must have planted the EV seed with H-D by showing the Sparkster at that Sept 2009 bike show. Does that mean I'm famous or rich? Nah!
