SPIDER Automation | 36V 350W Geared BLDC Hub Motor for Electric Bicycle | Front Spoke-Wheel Drive
The 36V 350W Geared BLDC Hub Motor is designed for electric bicycle conversion and compatible e-bike drive systems. It uses a brushless DC motor with an internal planetary gear mechanism to provide gear-assisted torque delivery for bicycle propulsion.
Operating at a rated voltage of 36V DC and a rated power of 350W, this motor is intended for compatible spoke-wheel assemblies. Its specified wheel-size compatibility covers 20-inch to 28-inch bicycle wheels, making it suitable for a range of e-bike conversion projects when the wheel mounting arrangement and electrical components are matched correctly.
Product Overview & Functional Design
Unlike a direct-drive hub motor, a geared hub motor uses an internal gear mechanism to transfer motor rotation to the wheel. The planetary gear arrangement provides gear reduction, allowing the motor to deliver increased torque at the wheel relative to its higher-speed motor rotation.
This design is intended for electric bicycle applications where gear-assisted drive performance is required. The brushless DC motor operates with a compatible electronic controller, while the spoke-wheel configuration allows integration into a suitable bicycle wheel assembly.
Technical Features & Performance Characteristics
- Brushless DC Motor Technology: Uses electronic commutation through a compatible motor controller rather than mechanical brushes.
- Planetary Gear Mechanism: Internal gear reduction supports torque delivery at the wheel for electric bicycle propulsion.
- 350W Rated Motor Power: Designed for compatible e-bike systems built around a 350W motor rating.
- 36V DC System: Intended for operation with a compatible 36V battery and motor controller.
- Spoke-Wheel Integration: Designed for use with a compatible spoke-wheel assembly rather than a complete wheel supplied as part of this package.
- Multiple Wheel Sizes: Specified for compatible 20-inch to 28-inch bicycle wheel applications.
- Gear-Assisted Drive: The internal planetary gears provide mechanical reduction to support wheel torque.
Applications
This geared BLDC hub motor is intended for electric bicycle conversion, replacement and compatible e-bike drive projects.
- Electric Bicycle Conversion: For converting a compatible conventional bicycle into an electrically assisted bicycle.
- Front-Wheel E-Bike Projects: For compatible front spoke-wheel drive assemblies.
- Electric Bicycle Replacement: For replacing an existing geared hub motor when voltage, power, mounting and wheel specifications match.
- DIY E-Bike Builds: For custom electric bicycle projects using a compatible 36V controller and battery system.
- Personal Mobility Projects: For suitable electrically assisted bicycle applications requiring a geared hub motor.
- Engineering & Prototyping: For development and testing of compatible electric bicycle drive systems.

Installation & Operating Recommendations
For proper operation, the hub motor must be installed in a mechanically compatible bicycle fork and connected to a suitable 36V BLDC motor controller. Wheel fitment, axle mounting, controller current capacity and electrical connections should all be matched to the motor and bicycle configuration.
- Use a Compatible 36V Controller: Select a BLDC controller designed for a 36V system and suitable for the motor’s rated current requirements.
- Match Battery Capability: Use a compatible 36V battery system capable of supplying the required operating current. Battery protection and discharge capability must be appropriate for the complete drive system.
- Confirm Wheel Fitment: Check the bicycle’s wheel size, fork mounting arrangement, axle dimensions and available clearance before installation.
- Use a Suitable Spoke Wheel: Select a compatible rim and spoke arrangement designed for the hub motor’s mechanical configuration.
- Secure the Axle: Ensure the motor axle is properly seated and secured using suitable mounting hardware and any required torque-retention components.
- Connect the BLDC Wiring Correctly: Match motor phase and sensor connections to the controller wiring diagram. Do not rely on wire colour alone.
- Perform an Initial Test: Test motor rotation and controller response with the driven wheel safely raised before riding.
- Check Mechanical Installation: Inspect wheel alignment, spoke tension, axle security and cable routing after installation.
