SPIDER Automation 36V 350W Brushless Geared Front Hub Motor | Planetary Gear Drive | Electric Bicycle Conversion
Product Overview & Geared Hub Construction
The SPIDER Automation 36V 350W Brushless Geared Front Hub Motor is designed for electric bicycle conversion systems using compatible front spoke-wheel assemblies. It combines a brushless DC motor with an integrated planetary gear reduction mechanism, providing increased output torque for wheel propulsion. This geared arrangement is suitable for applications where stronger starting drive and low-speed pulling capability are important.
The motor operates on a 36V DC electrical system and is specified for compatible bicycle wheel sizes from 20 to 28 inches. Its front-hub configuration allows it to be integrated into a suitable spoke-wheel assembly as part of an electric bicycle conversion. A compatible BLDC controller and correctly matched electrical and mechanical components are required for installation and operation.
Technical Features & Functional Characteristics
- Brushless Motor Technology: Uses an electronically commutated brushless DC motor that must be operated through a compatible BLDC controller.
- Planetary Gear Reduction: The integrated planetary gearbox reduces motor output speed while increasing torque at the geared output.
- Front Hub Drive Arrangement: Designed for integration into the front wheel of a compatible electric bicycle.
- Rated Output Speed: The specified rated speed is 328RPM, providing a reference for drivetrain and wheel-system matching.
- Rated Torque: The specified torque of 61kg-cm corresponds to approximately 5.98N·m.
- Spoke-Wheel Compatibility: Intended for compatible spoke-wheel assemblies in the 20–28 inch size range.
Electrical Configuration & Operating Characteristics
The motor is designed for a 36V DC supply and has a specified operating power of 350W. Its rated current is 14A, while the listed no-load current is 1000mA (1A). These electrical values should be considered when selecting the motor controller, battery system and associated wiring.
As a brushless motor, it requires a controller designed for the motor’s electrical configuration. A conventional brushed DC motor controller is not suitable. The controller’s voltage rating, current capability, motor phase arrangement and sensor compatibility must be checked before connecting the motor.
Applications
This geared front hub motor is intended for electric bicycle propulsion and compatible spoke-wheel conversion systems. Its integrated planetary gearing makes it suitable for applications requiring geared wheel drive.
- Electric Bicycle Conversion: For converting a compatible conventional bicycle into an electrically assisted bicycle.
- Front-Wheel Electric Drive: For electric bicycle designs using a powered front hub wheel.
- Urban Commuter E-Bikes: For compatible electric bicycle platforms used in daily commuting.
- Recreational Electric Bicycles: For electrically assisted bicycle configurations intended for recreational riding.
- Utility Bicycle Conversions: For suitable utility bicycle platforms requiring front-wheel electric propulsion.
- Electric Bicycle Prototyping: For engineering development and testing of compatible geared hub-motor drive systems.

Connection & Operating Recommendations
For reliable integration, select the controller, battery and wheel assembly according to the motor’s electrical and mechanical requirements. Confirm the front fork and axle compatibility before installation, as wheel-size compatibility alone does not establish mechanical fitment.
- Controller Selection: Use a 36V BLDC controller compatible with the motor’s phase and sensor configuration. Check its continuous current rating against the motor’s specified 14A rated current.
- Battery Matching: Use a battery system with a suitable voltage and current-delivery capability for the motor and selected controller.
- Wheel Compatibility: Confirm that the intended 20–28 inch spoke-wheel assembly is suitable for this hub motor and the bicycle frame.
- Front Fork Fitment: Check axle dimensions, fork spacing, retention arrangements and available clearance before mounting the motor.
- Electrical Connections: Follow the motor and controller wiring documentation. Do not assume wire colours or connector positions indicate phase or sensor functions.
- Initial Testing: Test the assembled drive system with the wheel safely raised and verify rotation and controller response before road operation.
- Mechanical Inspection: Check wheel alignment, spoke tension, axle retention and mounting security after installation and during routine maintenance.
