I did try on at the big e, last year. Do not remember the brand, but really liked it.
It was a cheaper bike with a nice battery.
Assume they will have a display/demo again,
Made me want this one, love this one...plenty of room for racks and would eat potholes, curbs and even small cars for dinner...lol.. And yes you could use it year round~ http://www.youtube.com/watch?v=kJD9nw2SuPY
