4. Installation (Setup)
Follow these steps for the correct installation of the Bafang G062 Rear Hub Motor. Ensure all safety precautions are observed.
- Prepare the Wheel: If not already spoked into a wheel, the motor must be laced into a suitable wheel rim. Ensure the spokes are tensioned correctly.
- Install Freewheel: Thread the compatible freewheel onto the motor's freewheel body. Ensure it is tightened securely.
- Mount Disc Brake Rotor: Attach the disc brake rotor to the motor's disc brake mount using appropriate bolts. Ensure bolts are torqued to manufacturer specifications.
- Install Motor into Frame:
- Carefully insert the motor axle into the rear dropouts of your bicycle frame. The motor is designed for a 190mm drop-out width.
- Ensure the motor cable exits the frame in a way that prevents pinching or damage.
- Install the axle washers and nuts. Tighten the axle nuts securely to prevent the motor from shifting during operation.
- Connect Motor Cable: Connect the motor's main power cable and sensor cable to the corresponding ports on your e-bike controller. Ensure the connections are firm and waterproof.
- Route Cables: Securely route all cables along the bicycle frame using cable ties or clips, ensuring they do not interfere with moving parts or steering.
- Final Checks: Before riding, perform a thorough check of all installed components. Verify that the wheel spins freely, the brake system functions correctly, and all electrical connections are secure.
5. Operation
Once the motor is correctly installed and connected to a compatible e-bike system (controller, battery, display, and sensors), its operation is typically managed through the e-bike's control unit.
