Maximum available speed. It can be influenced by driver weight, road conditions, and wind.
Battery capacity expressed in watt-hours. For motors with different voltages but with the same power, a higher watt-hour battery means greater range.
Lithium-ion batteries have a significantly longer battery life than AGM batteries, with a minimum of 1000 charge cycles compared to the maximum of 300 with AGM.
The maximum range you can do on one charge. Manufacturers' data is generally based on measurements made with a 80-kg driver on a flat road in battery-saving mode.
