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.
