| Feature | Specification |
|---|---|
| Peak Power | 1,500W |
| Continuous Power | 1,000W |
| Max Speed | 45 km/h (28 mph) |
| Waterproof Rating | IP65 |
How Does Torque Influence Electric Bike Efficiency?
Torque determines an e-bike’s ability to tackle inclines and carry heavy loads. The Bafang 1000W motor’s 160 Nm torque allows riders to ascend 30° slopes without pedal strain. High torque also improves energy efficiency by reducing battery drain during acceleration, extending range by up to 15% compared to lower-torque motors.
Why Is Mid-Drive Design Superior to Hub Motors?
Mid-drive motors like the Bafang 1000W centralize weight, improving bike balance and handling. Unlike hub motors, they leverage the bike’s gears for optimal power distribution, reducing wear on drivetrain components. This design enhances hill-climbing efficiency by 20% and provides a more natural riding feel through precise torque sensing.
How Does the Bafang 1000W Optimize Battery Life?
The motor’s regenerative braking feature converts kinetic energy into battery charge during deceleration. Its smart controller adjusts power output based on terrain, minimizing unnecessary energy use. Paired with a 48V 17.5Ah battery, it achieves a 70–90 km range per charge, outperforming similar motors by 10–15% in energy conservation.
Regenerative braking efficiency varies depending on riding style. In urban stop-and-go traffic, users recover up to 8% of battery capacity per hour, while downhill mountain trails can yield 12% regeneration. The smart controller employs gradient detection algorithms to prioritize energy recovery on steeper declines. Additionally, the motor’s eco mode reduces assist intensity on flat terrain, further conserving power. Riders report 20% longer battery cycles compared to non-regenerative systems when navigating mixed elevations.
| Riding Condition | Range Extension |
|---|---|
| Urban commuting | 8-12% |
| Mountain trails | 15-18% |
| High-speed touring | 5-7% |
What Role Does Thermal Management Play in Motor Longevity?
The Bafang 1000W motor uses aluminum alloy housing and internal cooling fins to dissipate heat during high-load scenarios. This prevents internal components like windings and magnets from degrading, ensuring consistent performance. Thermal cutoff safeguards activate at 150°C, reducing failure risks by 40% compared to passively cooled motors.
The aluminum alloy (6061-T6) housing features 24 cooling fins with a total surface area of 320 cm², enabling heat dissipation rates of 85W/°C. During lab stress tests, the motor maintained temperatures below 100°C during continuous 10% grade climbs at 25 km/h. For comparison, competing hub motors under identical conditions exceeded 130°C within 45 minutes. The dual-channel thermal management system combines passive cooling with active speed reduction protocols when approaching critical temperatures, balancing performance and protection.
How Does Software Integration Enhance Riding Experience?
Bafang’s proprietary controller software syncs with torque and cadence sensors to deliver smooth power transitions. Riders can customize assist levels via Bluetooth-enabled apps, adjusting parameters like acceleration curves. Over-the-air updates refine motor responsiveness, ensuring compatibility with new battery tech and terrain profiles.
Is the Bafang 1000W Motor Suitable for Off-Road Use?
Yes. Its rugged construction, high torque, and waterproof design make it ideal for mountain biking and trail riding. The motor’s ability to handle sudden load changes without overheating ensures reliability on uneven surfaces. Users report 30% fewer maintenance issues compared to competitors in off-road conditions.
