| QS 205 150mm Dropout 5000W Wheel | Riders with 150mm inner distance forks | 150mm dropout | High-speed option with 3.5T thrust. |
| NB POWER 19×1.6 Black Rim 3.5T 5000W | Compact rear-wheel builds needing strong power | 150mm dropout; 19×1.6 rim | Street-tire compatibility noted; ensure fork clearance. |
| SASKATE 11 Inch 5000W Hub Motor | Electric scooters or small-motorcycle builds needing IPX6 resistance | 11 inch hub motor; detailed dropout varies | Dual Hall sensors for safe operation; robust aluminum body. |
buyer profiles:
– Fat-bike builders and performance-oriented riders typically value high torque and wide tires.
– Riders with specific dropout constraints benefit from exact measurements (150mm, 190mm, etc.).
– Those seeking dual-sensor safety and weather resistance may prefer IPX6-rated or dual Hall sensor designs.
– For scooter-style setups, compact 11-inch hubs provide a different form factor and durability.
SZWEDI 72V5000W Hub Motor Wheel Kit
Features: 72V5000W controller; current limit 80A; dimensions: 165mm x 100mm x 60mm. Components include left pedal sensor, 1T4 cable harness, thumb throttle, electric brake, and controller bag. Battery is not included; requires a compatible 72V battery with an 80A BMS. Best for: fat-bike builds needing reliable power delivery and integrated components. Limitation: compatibility with batteries must be verified to prevent damage.
QS205 50H 3.5T 190mm Dropout 72V 5000W
Features: 72V 5000W motor, rear dropout 190mm, axle size M16*10mm; speeds with 3.5T: around 840 RPM, 4T: 770 RPM, 5T: 650 RPM. Best for: riders needing a high-torque rear-wheel for fat-bike setups with ample dropout width. Better for: riders who prioritize a broad torque curve and wide compatibility. Caution: confirm compatibility with your frame’s dropout and mounting standards before purchase.
QS 205 150mm Dropout 5000W Wheel
Features: 5000W motor with 150mm rear dropout; best for frames with a longer inner distance. Best for: riders who require a higher dropout measurement while retaining strong speed. Limitation: requires precise frame clearance and may need longer chain or belt routing adjustments. Choose this if your fork spacing is fixed at 150mm and you want consistent power at speed.
NB POWER 19×1.6 Black Rim 3.5T 5000W
Features: 19×1.6 black rim, 3.5T, 5000W; rear-drive configuration. Best for: compact, power-dense builds with standard 150mm dropout. Better for: riders who want a strong street-focused wheel with a robust wheel rim. Caution: verify tire clearance and frame compatibility to avoid interference with brake mounts or fenders.
SASKATE 11 Inch 5000W Hub Motor
Features: 11-inch hub motor with IPX6 waterproof rating; aluminum alloy body; dual Hall sensors for safety and performance. Best for: electric scooters or compact motorcycles requiring weather resistance and reliable acceleration. Better for: riders who want a safer top-end performance with sensor redundancy. Limitation: the 11-inch form factor may require frame-specific adapters and careful mounting to ensure clearance.
Buying Guide
What matters most when choosing a 5000W hub motor:
- Dropout compatibility: Confirm the rear dropout measurement (150mm, 170mm, 190mm, etc.) matches your frame.
- Wheel size and tire compatibility: Ensure the wheel diameter and tire width fit your bike or scooter’s geometry and brakes.
- Controller and BMS compatibility: Check the current and voltage ratings and ensure your battery BMS matches 80A or as specified by the kit.
- Sensor and safety features: Dual Hall sensors can improve safety and reliability, particularly in high-torque setups.
- Weather resistance: IP ratings matter for riders in varied weather; IPX6-rated hubs withstand rain better.
- Installation considerations: Verify mounting hardware, axle size, and whether additional adapters are needed for your frame.
FAQ
- What is a 5000W hub motor best used for?
– For high-torque, fast-accelerating rear-wheel propulsion on fat bikes, scooters, or go-karts. - Do I need a special battery for a 5000W kit?
– Yes. A compatible high-current battery with an appropriate BMS (often 80A or higher) is required for safe operation. - Will a 150mm dropout fit all bikes?
– No. Measure your frame’s rear dropout distance and axle specifications to ensure compatibility. - Are dual Hall sensors necessary?
– They improve safety and redundancy, especially in high-torque systems, but not strictly mandatory. - Can I use these motors on street bikes?
– They are typically designed for fat bikes or specialized builds; ensure frame, brake, and tire clearance.
