Range by battery

E-Bike Range by Battery Capacity

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.

20 km/h · flat terrain

Quick Answer

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, and 1000Wh 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.

Battery tiers

Battery Capacity vs Range

250-400Wh: Entry Level

Range
30-60 km
Notes
Suitable for short commutes and light use. Common in budget e-bikes.

400-600Wh: Standard

Range
50-100 km
Notes
Most common capacity. Good balance of range and weight. Suitable for most riders.

600-800Wh: Extended Range

Range
80-130 km
Notes
Ideal for longer commutes and touring. Heavier but provides excellent range.

800-1000Wh+: Premium

Range
100-180+ km
Notes
Maximum range for touring and long-distance riding. Heavy but unmatched range.

Understanding Battery Capacity

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.

How to Calculate Wh

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.

Range Estimation Formula

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.

Factors Affecting Range per Wh

  • Speed: Higher speed = more Wh/km consumed
  • Terrain: Hills require more energy per km
  • Weight: Heavier loads consume more energy
  • Wind: Headwinds increase energy consumption
  • Riding Style: Active pedaling reduces energy consumption
