Have been asking $500, but will consider all reasonable offers. These are $999 on the NIU website (this is the MAX version -- not the Pro or Sport), and they are sold out. Bought new/open box and never taken out of the box.
Max speed of 24 mph, 40.4-mile max range, front and rear disc brakes, self-sealing tires, extremely bright headlight, climbs a 25% incline.
