NBPOWER Editorial Review
The QS 273 electric motor appears to be a popular option for electric motorcycle and scooter enthusiasts. Based on the Q&A section, the motor is available in two different versions, one with high speed and the other with high torque. It can be shipped to the USA via FedEx, with no extra charges or customs fees. However, it cannot be installed on a 12-inch wheel, and it requires a minimum of 18-inch rim size. The motor can take 10-gauge spokes, and the matching spokes can be provided for free upon request. The manufacturer has a 5T 8000W motor and a 19-inch 3.5T 8000W motor available in their USA warehouse. Overall, customers who have used the QS 273 electric motor seem satisfied with its performance and specification. However, many questions are related to compatibility with specific wheel sizes and spoke thickness, suggesting that some customers may have difficulty installing the motor on their own.
