Please read this manual thoroughly before your first ride to ensure proper assembly and understanding of all functions and safety precautions.
Safety Information
Your safety is paramount. Always wear a helmet and appropriate safety gear when riding. Adhere to all local traffic laws and regulations. Regular inspection and maintenance are crucial for safe operation.
- Pre-Ride Check: Before each ride, inspect tires for proper inflation, brakes for functionality, and ensure all bolts and quick releases are securely tightened.
- Battery Safety: Only use the original charger provided. Do not expose the battery to extreme temperatures or puncture it. Ensure the battery is securely locked in place before riding.
- Braking: Practice braking in a safe area to understand the bike's stopping distance. Use both front and rear brakes simultaneously for optimal stopping power.
- Autocruise Control Warning: Be aware that the autocruise control feature, if activated, may not disengage immediately upon releasing the throttle. Always use the brakes to disengage cruise control to prevent unintended acceleration, especially in challenging terrain or traffic.
- Weight Limits: Do not exceed the maximum load capacity of 330 lbs (150 kg) for the bike and 110 lbs (50 kg) for the rear seat.
- Visibility: Use lights and reflective gear, especially when riding in low-light conditions.
Setup and Assembly
Your Rattan electric bike comes partially assembled. Follow these steps to complete the setup:
- Unpacking: Carefully remove the bike and all components from the packaging. Retain packaging for future transport or storage.
- Handlebar Installation: Unfold the handlebar stem and secure it in the upright position. Adjust the handlebar height and angle for comfortable riding, then tighten all fasteners.
- Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Ensure they are fully threaded and tightened.
- Seat Post Adjustment: Insert the seat post into the frame and adjust the height to allow for a slight bend in your knee when the pedal is at its lowest point. Secure with the quick-release lever.
- Battery Installation: Insert the 48V 13AH removable battery into its compartment and ensure it clicks securely into place. Use the key to lock it if applicable.
- Tire Inflation: Inflate the 20" x 4.0 fat tires to the recommended pressure indicated on the tire sidewall.
- Brake Check: Test both front and rear brakes to ensure they engage properly and stop the wheels effectively. Adjust cable tension if necessary.

- Charging: Connect the charger to the bike's charging port or directly to the removed battery. A full charge typically takes 4-6 hours. Do not overcharge.
- Battery Removal: To remove the battery, unlock it with the key and slide it out. This is useful for charging indoors or for security.

Maintenance
Regular maintenance will prolong the life of your Rattan electric bike and ensure safe operation.
- Cleaning: Clean the bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.
- Tire Care: Check tire pressure before each ride. The 20" x 4.0 fat tires are durable but can be punctured. Inspect for wear and tear.
- Brake Maintenance: Regularly check brake pads for wear and replace them when necessary. Ensure brake levers are responsive and cables are not frayed.
- Chain Lubrication: Keep the chain clean and lubricated to ensure smooth gear changes and prevent rust.
- Fastener Check: Periodically check and tighten all bolts and screws, especially on critical components like the handlebars, seat post, and wheels.
