4. Setup and Installation
Follow these steps for proper installation of the rear hub motor:
- Prepare the Wheel: Ensure you have a compatible 26-inch or 28-inch rear wheel. The motor is designed to be integrated into the rear wheel.
- Motor Orientation: When installing the motor, ensure the cable guide is positioned on the left side of the bicycle (non-drive side). This is crucial for proper cable routing and protection.
- Disc Brake Installation: The motor is compatible with 6-hole disc brakes. Mount your disc brake rotor securely to the designated 6-hole pattern on the motor hub. Ensure all bolts are tightened to the manufacturer's specifications (typically 5 Nm for M5x8mm bolts).
- Electrical Connection: Connect the motor's 9-pin plug to the corresponding connector on your e-bike's wiring harness. Ensure the connection is firm and fully seated.
- Cable Routing: Route the motor cable carefully along the bicycle frame, securing it with cable ties to prevent snagging or damage.
- Final Checks: Before riding, verify that the wheel spins freely, the brake operates correctly, and all electrical connections are secure.

5. Operating Instructions
Once the motor is correctly installed and connected, its operation is typically controlled by the e-bike's main display and control unit. Refer to your specific ZÜNDAPP e-bike model's user manual for detailed instructions on:
- Turning the e-bike system on and off.
- Selecting pedal assist levels (e.g., Eco, Tour, Sport, Turbo).
- Monitoring battery level and speed.
- Using walk-assist mode (if available).
The motor provides assistance based on your pedaling input, detected by the integrated speed and Hall sensors. The level of assistance will vary depending on the selected mode and your pedaling effort.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your motor:
- Cleaning: Keep the motor housing clean from dirt, mud, and debris. Use a damp cloth; avoid high-pressure washing directly on the motor or electrical connections.
- Cable Inspection: Periodically check the motor cable and its connectors for any signs of wear, cuts, or damage. Ensure connections remain secure.
- Bolt Tightness: Regularly inspect all mounting bolts, especially those for the disc brake rotor and wheel axle, to ensure they are tightened to the correct torque specifications.
- Environmental Protection: While the motor is designed for outdoor use, avoid prolonged exposure to extreme weather conditions or submersion in water.
7. Troubleshooting
If you encounter issues with your motor, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not providing assistance | Battery low or disconnected, loose electrical connection, sensor issue, system error. | Check battery charge and connection. Inspect all cables and the 9-pin connector for secure fit. Restart the e-bike system. Consult your e-bike's main manual for error codes. |
