① This is tested while riding under full power, 75kg load, 25°C, 15km/h average speed on the smooth pavement, riding habit, environment, temp, road condition, load, and other factors will affect the ranges.
② The maximum cruising speed is measured at the 25 ℃, the payload of 75 kg, full electric voltage, and flat pavement. The factors like driving habits, environmental temperature, road surface condition, payload, etc. will affect the speed.
③ This slope was measured in the case when the load is 75 Kg.
④ Charging time varies with the ambient temperature and the battery capacity that may change in the course of time.
