Battery capacity is the primary factor determining e-bike range. Learn how different battery sizes (measured in watt-hours) affect your e-bike's distance.
At moderate speed (20 km/h) on flat terrain: a 250Wh battery gives 30-60 km,500Wh gives 80-120 km,750Wh gives 120-180 km, and1000Wh gives 160-240 km.
Calculate Wh from your battery label: Wh = Voltage (V) x Amp-hours (Ah). For example, a 36V 13.9Ah battery = 500Wh. Divide Wh by energy consumption per km (typically 5-15 Wh/km) to estimate range. Eco mode extends range 30-50% over sport mode.
Range: 30-60 km
Suitable for short commutes and light use. Common in budget e-bikes.
Range: 50-100 km
Most common capacity. Good balance of range and weight. Suitable for most riders.
Range: 80-130 km
Ideal for longer commutes and touring. Heavier but provides excellent range.
Range: 100-180+ km
Maximum range for touring and long-distance riding. Heavy but unmatched range.
Battery capacity is measured in watt-hours (Wh), which represents the total energy the battery can store. Higher Wh means more energy and longer range.
Watt-Hours (Wh) = Voltage (V) × Amp-Hours (Ah)For example, a 36V battery with 13.9Ah capacity = 500Wh. This is the standard way to compare battery capacity across different e-bikes.
Basic range estimation:
Range (km) = Battery Capacity (Wh) / Energy Consumption per km (Wh/km)Energy consumption per km typically ranges from 5-15 Wh/km depending on speed, terrain, weight, and other factors.
