result from the riding test conducted uninterruptedly with load of 60kg, at the speed of 15-25km/h, and on the flat
and hardened road surface, from full charge to full power consumption.; Driving habits, temperature, load, tire
pressure, road environment and other factors will affect the actual cruising distance.
