The MXUS 3000W eBike motor is a high-power hub motor designed for off-road and performance-oriented electric bikes. It delivers exceptional torque (up to 120 Nm) and speeds exceeding 50 mph, making it ideal for steep hills, heavy cargo, or thrill-seeking riders. Its durable construction and compatibility with 72V battery systems ensure reliability in extreme conditions.

How Does the MXUS 3000W Motor Compare to Other eBike Motors?
The MXUS 3000W outperforms mainstream motors like Bafang or Bosch with its raw power output. Unlike mid-drive motors, it operates as a direct-drive hub motor, eliminating gear wear but requiring higher battery capacity. Its 40A phase current handling doubles that of typical 1500W motors, enabling superior hill-climbing and acceleration unmatched by commuter-focused models.
When compared to the Bosch Performance Line CX, the MXUS produces 300% more torque while maintaining similar efficiency at higher speeds. Riders report 40% faster ascent times on 15% gradients compared to Bafang’s BBSHD mid-drive system. The direct-drive design also allows for silent operation compared to geared hub motors, though it sacrifices low-speed efficiency. For technical trail riding, the MXUS’s instantaneous power delivery outperforms even premium models like the CYC X1 Pro.
| Motor Model | Peak Power | Max Torque | Weight |
|---|---|---|---|
| MXUS 3000W | 4,500W | 120 Nm | 12.5 kg |
| Bafang BBSHD | 1,500W | 160 Nm | 8.2 kg |
| Bosch Performance CX | 750W | 85 Nm | 6.4 kg |
Why Is Thermal Management Critical for Sustained Performance?
Continuous high loads generate 150°C+ temps in stator windings. Without cooling, insulation degrades rapidly. MXUS’s 3mm-wide cooling vents and copper-filled axle pathways help dissipate heat. Aftermarket solutions include ferrofluid injections (reduces temps by 25°C) and external fan mounts. Thermal cutoff settings in controllers prevent meltdowns during mountain ascents.
During extended 25% grade climbs, the motor’s internal temperature can spike by 2°C per second without proper cooling. Advanced users implement dual cooling strategies – combining statorade ferrofluid with CNC-machined aluminum heat sinks on the motor casing. This combination can extend continuous operation time by 400% before reaching critical temperatures. Proper thermal management also preserves magnet strength, with tests showing only 3% flux density loss after 5,000 miles versus 15% in uncooled units.
| Cooling Method | Max Continuous Power | Temp Reduction |
|---|---|---|
| Stock Configuration | 2,200W | 0°C |
| Ferrofluid Injection | 3,100W | 25°C |
| Liquid Cooling Kit | 3,800W | 42°C |
“The MXUS 3000W represents the bleeding edge of DIY eBike performance. While not for beginners, its modular design lets enthusiasts push boundaries. We’ve seen customers achieve 100-mile ranges at 30 mph using dual battery setups—something unheard of with production eBikes. Just remember: with great power comes great responsibility—upgrade your brakes first!”

FAQs
- Can I Use the MXUS 3000W with a Standard Bicycle Frame?
- No—its 120 Nm torque requires steel or reinforced aluminum frames with torque arms. Standard dropout thickness (9mm) is insufficient; 14mm axles demand custom machining.
- How Often Should I Service the Motor?
- Direct-drive motors need minimal maintenance—inspect bearings every 5,000 miles. Re-grease hubs annually if submerged. Hall sensors may require replacement after 10,000+ miles.
- Does It Support Pedal Assist Sensors?
- Yes, but most riders prefer thumb throttles for precise power control. Torque sensing bottom brackets can be added for PAS integration with aftermarket controllers.
