3. Compatibility and Important Notes
Before installation, please review the following compatibility requirements and notes:
- Suitable for 36V-48V lithium and lead-acid batteries.
- Not suitable for bicycles with wheels under 16 inches.
- Not compatible with 4.0 tires, tubeless tires, or solid tires.
- The final performance is influenced by the bicycle tire type and installation quality.
- If your bicycle tires are aged, replace them before installation to prevent excessive wear.

Bicycle Frame Compatibility
Ensure your bicycle frame meets the following criteria for proper installation:
Image: Bicycle frame compatibility guide. Check the distances (A, B, C, D) on your frame to ensure proper fit.
Refer to the image above to confirm your bicycle's frame dimensions are suitable. A minimum gap of 2.7cm is generally required for mountain bikes, cycling road bikes, and commuter bikes. Bicycles over 16 inches with a back fork are generally suitable. Bicycles without a back fork, with a spring in the back fork, or without an installation location are not suitable. 4.0 snow tires are also not supported.
Tire Type Compatibility
The most suitable tires for this conversion kit are bald tires or obscure tires. If your bicycle has a quick-release screw washer that is higher than 2.8cm, it may need to be removed for proper installation.

4. Setup and Installation
Follow these steps carefully for proper installation of your electric bike conversion kit.
Installation Steps Overview

- Prepare: Gather your bicycle and all kit accessories.
- Clutch Switch: Pull the clutch switch to the snap position.
- Install Baffle Plate: Install the fixed baffle plate and insert the quick screw into the fixed baffle.
- Friction Wheel Gap: Ensure the distance between the friction wheel and the tire is 2-3mm.
- Rotate and Tighten: Rotate and tighten the screws securely.
- Clutch Line: When installing and turning the clutch line, ensure it is rotated in a large arc to prevent damage.
Important Installation Considerations

- The clutch switch, when turned ON, engages the boost state.
- Ensure the friction wheel bites the tire tightly when engaged.
- When the clutch switch is released, the system is in a non-assist state.
- Maintain a 2-3mm gap between the friction wheel and the tire for optimal performance and to prevent wear.
Controller Wiring
Proper wiring of the controller is crucial for the kit's functionality. Refer to the diagram and video below for guidance.

Note: Only use the provided controller with the BAIZIFU motor. Other controllers may not be compatible and could lead to malfunctions or damage.
5. Operating Instructions
Once installed, operate your electric bike by engaging the clutch switch for motor assistance. The motor provides power to assist your pedaling. Always ensure the friction wheel is properly engaged with the tire for effective power transfer.
Safety Precautions
- Always wear a helmet and appropriate safety gear when riding.
- Be aware of your surroundings and obey all traffic laws.
- Exercise caution when riding in wet conditions, especially with deep tread pattern tires, as they may skid easily.
- Regularly check all connections and mounting hardware to ensure they are secure.
6. Maintenance
To ensure the longevity and optimal performance of your BAIZIFU Electric Bike Conversion Kit, follow these maintenance guidelines:
- Tire Condition: Regularly inspect your bicycle tires for wear and tear. Replace severely aged tires before using the kit to prevent damage to the friction wheel and ensure safe operation.
- Friction Wheel: Keep the friction wheel clean and free from debris to maintain good contact with the tire.
- Connections: Periodically check all electrical connections and mechanical fasteners for tightness.
- Battery Care: Follow the manufacturer's instructions for your specific 36V-48V battery for charging, storage, and general care.
- Cleaning: Clean the motor and controller units with a damp cloth. Avoid using high-pressure water jets directly on electrical components.
7. Troubleshooting
If you encounter issues with your electric bike conversion kit, consider the following common troubleshooting steps:
- No Power:
- Check if the battery is charged and properly connected.
- Verify all wiring connections are secure, especially the power cable to the controller and battery.
- Ensure the on-off switch is in the 'ON' position.
- Motor Not Engaging:
- Confirm the clutch switch is fully engaged.
- Check the gap between the friction wheel and the tire (should be 2-3mm). Adjust if necessary.
- Inspect the friction wheel for wear or damage.
- Intermittent Power:
- Examine all wiring for loose connections or damage.
- Ensure the battery has a stable charge.
- Unusual Noises:
- Check for any foreign objects caught in the motor or friction wheel.
- Ensure all mounting hardware is tight.
If these steps do not resolve the issue, please contact customer support for further assistance.
