This is a 2002 model EVT 4000. They get 30 miles/hr max speed and with fresh batteries will do over 20 miles range. It's very well made and the EVT corporation has been around for a long time. 2002 was the first year they were imported to the U.S. They never sold it with this color combination, but Electric Motorsport had put this bike together as a demonstration unit and I liked the mix of colors as a way of being more visible. To me visibility equals safety.

4 12v 50ah plus 1 12v 18ah
