Introducing the Neodymium Subwoofer Motor, a brushless non-gear hub motor designed for electric bicycles. This motor features a voltage of 36V, wattage between 201 and 300W, and comes in a sleek black or silver color. With a diameter of 160mm and a width of 135??2mm, this compact motor boasts a rated output power of 250W and a maximum output power of 400W. It also delivers a maximum output torque of 25Nm and operates with an extremely high efficiency of ??89%. The motor is rated at 30V and can achieve a rated revolution between 160 and 260 r/min. Despite its powerful performance, this motor weighs only 3.8 kg, making it a lightweight addition to your e-bike.

The Neodymium Subwoofer Motor stands out for its numerous advantages. Firstly, it features a built-in 7Ah battery, controller, and sensor, allowing for optimal integration and ease of use. Secondly, the motor is equipped with a dynamic torque sensing system, which intelligently adjusts the amount of assistance based on your pedaling force. Thirdly, it has a slope induction system that detects uphill or downhill conditions and provides the appropriate level of support. Fourthly, this motor supports extended range batteries for longer rides. Fifthly, it supports GPS positioning for easy navigation and tracking of your rides. Lastly, it can be controlled wirelessly, providing a convenient and seamless user experience. At Raydafon, we can produce this advanced motor to meet your e-bike needs.


The Neodymium Subwoofer Motor is designed with versatility in mind, making it suitable for various applications. It can be used to convert a regular pedal bicycle into an electric bike, providing propulsion and enhancing the overall riding experience. It's an ideal choice for commuting as it makes it easier to cover longer distances and tackle hilly terrain. Moreover, e-bikes powered by this motor offer an eco-friendly transportation option, producing zero emissions. For those who enjoy recreational riding, this motor can enhance your experiences by providing additional power and assistance. It's also suitable for cargo and delivery services, allowing businesses to transport goods efficiently. Lastly, this motor can be used for fitness and health purposes as it still requires the rider to pedal, thereby providing a balance between exercise and assistance.

The Neodymium Subwoofer Motor for e-bike system consists of several integrated components that work together to provide electric assistance. The motor, built into the wheel hub, is the heart of the system. The controller manages the operation of the motor, regulating the flow of electric current from the battery. The system is powered by a battery pack, typically lithium-ion, that stores and supplies electrical energy to the motor. Various sensors provide feedback to optimize the motor's performance, and a user interface allows the rider to select different power modes and monitor battery level. When the rider begins to pedal, the sensors detect the pedaling force and send a signal to the controller, which then determines the appropriate level of electric assistance.

Choosing the right Neodymium Subwoofer Motor for your electric bicycle depends on several factors. You need to evaluate the power and torque output of the motor, check the voltage and capacity of the battery, and determine which assistance modes you prefer. Ensure that the motor is compatible with your bicycle frame and wheel size, and consider the weight of the motor as it affects the overall weight distribution of the bike. Lastly, consider the ease of installation and integration of the motor into your bike.
Proper maintenance of the Neodymium Subwoofer Motor is crucial for its longevity and optimal performance. Regular cleaning, checking and tightening bolts, lubrication, battery maintenance, sensor alignment, inspecting wiring, and brake adjustment are some of the maintenance tasks that can keep your motor in good condition.
