The Dongfang Swift E 2000W Brushless Electric Motorcycle is a high-performance, eco-friendly commuter bike featuring a brushless motor for enhanced efficiency, a top speed of 45 mph, and a 60-mile range. Its lightweight design, regenerative braking, and low maintenance requirements make it ideal for urban riders seeking cost-effective, sustainable transportation.
How Does the e-Ride Pro SS Compare to the Surron Ultra Bee in Terms of Performance?
How Does the 2000W Brushless Motor Enhance Performance?
The brushless motor eliminates friction-prone components, improving energy efficiency by 20% compared to brushed motors. It delivers consistent torque, reduces overheating risks, and extends battery life. This design ensures smoother acceleration and quieter operation, making it suitable for both city commutes and moderate off-road terrain.
What Battery Technology Powers the Swift E 2000W?
A 72V 32Ah lithium-ion battery provides 2.3kWh capacity, rechargeable in 4-6 hours. It features advanced Battery Management System (BMS) protection against overcharging, temperature fluctuations, and voltage drops. The modular design allows easy replacement, with 1,500+ charge cycles retaining 80% capacity.
The battery’s thermal management system uses aluminum cooling plates to maintain optimal temperatures between -20°C and 55°C. Riders can choose between three charging modes: Standard (6A), Rapid (10A), and Balanced (8A with cell balancing). Field tests show 95% capacity retention after 800 cycles when charged at 25°C ambient temperature. For cold climates, the optional self-heating battery pack reduces charging time by 40% at 0°C.
| Charging Mode | Current | Time (0-100%) |
|---|---|---|
| Standard | 6A | 6 hours |
| Rapid | 10A | 4 hours |
| Balanced | 8A | 5 hours |
How Does Regenerative Braking Improve Efficiency?
The motorcycle recovers 15-20% of kinetic energy during deceleration, feeding it back into the battery. This extends range by up to 12 miles per charge while reducing brake pad wear. Three braking modes let riders customize energy recovery intensity based on traffic conditions.
What Safety Features Are Integrated into the Design?
Dual hydraulic disc brakes (front 265mm, rear 220mm) provide stopping power within 3.2 seconds from 30 mph. LED lighting ensures 360° visibility, while the IP67-rated motor withstands water immersion up to 1 meter. The anti-theft system includes GPS tracking and motion-activated alarms.
How Does It Compare to Gas-Powered Motorcycles?
The Swift E 2000W operates at 1/8th the cost per mile ($0.03 vs. $0.24 for gas). It produces zero emissions and 65 dB noise (vs. 85-100 dB for combustion engines). However, long-distance touring beyond 60 miles requires planning for charging stations.
Ownership cost analysis reveals significant savings over five years. While the upfront price is 15% higher than equivalent 125cc gas bikes, the electric model saves $1,200 annually in fuel and $300 in maintenance. Regulatory advantages include access to carpool lanes in 22 states and exemption from emissions testing. Performance comparisons show identical 0-30 mph acceleration times, though gas bikes retain an edge in top speed (75+ mph vs. 45 mph).
| Factor | Swift E 2000W | 125cc Gas Bike |
|---|---|---|
| Annual Fuel Cost | $98 | $780 |
| CO2 Emissions | 0 tons | 1.1 tons |
| Service Intervals | 1,200 miles | 600 miles |
“The Dongfang Swift E redefines urban mobility by merging motorcycle agility with EV sustainability. Its brushless motor tech sets a new benchmark—we’ve measured 92% energy conversion efficiency, surpassing industry averages by 18%. For cities targeting emission reductions, this model could displace 4.7 tons of CO2 annually per unit compared to ICE counterparts.”
