48V 50Ah Battery Range Estimation - Real-World Performance Data
Actual riding range based on different motor power configurations and usage conditions
How We Calculate Range
Range estimates are based on 48V 50Ah (2400Wh) battery capacity, factoring in real-world efficiency losses, terrain variations, and average riding conditions. Actual range may vary based on rider weight, terrain, speed, temperature, and riding style.
BMS Configuration & Estimated Range
| BMS Current | Motor Power | Average Speed | Estimated Range |
|---|---|---|---|
| 40A BMS | 800W - 1500W | 20-30 km/h (12-19 mph) | 90-120 km (56-75 miles) |
| 60A BMS | 1500W - 2000W | 30-40 km/h (19-25 mph) | 70-100 km (43-62 miles) |
| 80A BMS | 2000W - 3000W | 40-55 km/h (25-34 mph) | 50-80 km (31-50 miles) |
Factors Affecting Range
Rider & Load Weight
Additional weight reduces range by approximately 10-15% per 25kg (55lbs).
Terrain & Elevation
Hilly areas can reduce range by 30-40% compared to flat terrain.
Temperature Conditions
Colder temperatures (below 10°C/50°F) can reduce range by 15-25%.
Riding Style & Speed
Aggressive acceleration and high speeds significantly reduce range.
Note: All range estimates are based on laboratory testing under controlled conditions. Actual range will vary based on real-world usage factors.
