4. Assembly Instructions
The RoyalBaby FS-5 bicycle arrives 95% pre-assembled. The following steps detail the final assembly process, which typically takes about 15 minutes with the included tools.
- Install the Front Wheel: Carefully insert the front wheel into the fork dropouts. Ensure the wheel is centered and the quick-release skewer or axle nuts are tightened securely.
- Attach the Handlebar: Insert the handlebar stem into the fork's steerer tube. Align the handlebar perpendicular to the front wheel and tighten the stem bolt firmly.
- Install the Seat Post and Saddle: Insert the seat post, with the saddle attached, into the frame's seat tube. Adjust the height so the rider can comfortably touch the ground with their toes. Secure it using the quick-release lever or bolt.
- Attach Pedals: Identify the Left (L) and Right (R) pedals. The left pedal threads counter-clockwise, and the right pedal threads clockwise. Apply a small amount of grease to the threads if available. Tighten both pedals securely with the provided wrench.
- Install Training Wheels (if applicable): Attach the training wheels to the rear axle. Ensure they are positioned to provide stability without lifting the rear wheel too high off the ground, allowing the child to learn balance.
- Attach Reflectors and Bell: Install the front (white) and rear (red) reflectors for visibility. Mount the bell on the handlebar in an easily accessible position.
- Attach Water Bottle Holder: Secure the water bottle holder to the designated mounts on the frame.
For detailed visual guidance, refer to the diagrams in the included instruction manual and use the complementary tools provided.

5. Operation
Understanding how to operate the RoyalBaby FS-5 bicycle ensures a safe and enjoyable riding experience.
- Riding Position: Ensure the child can comfortably reach the ground with their toes while seated on the saddle. The handlebars should be at a comfortable height and angle, allowing for easy steering and braking.
- Braking: The FS-5 features dual handbrakes (caliper for the front, drum for the rear). Instruct the child to use both brake levers simultaneously for effective and controlled stopping. Practice braking in a safe, open area away from traffic.
- Steering: Guide the child on how to steer by gently turning the handlebars in the desired direction. Encourage looking where they want to go.
- Pedaling: If using the EZ Balance to Pedal feature, ensure the pedals are correctly installed for pedaling mode. Teach the child to start pedaling by pushing off and then placing their feet on the pedals.
- Adjustments: The seat and handlebar are fully adjustable to accommodate your child's growth. Periodically check and adjust these components to maintain a proper fit.
6. Maintenance
Regular maintenance will prolong the life of your RoyalBaby FS-5 bicycle and ensure safe operation.
- Tire Pressure: Check tire pressure before each ride. Maintain the recommended pressure indicated on the tire sidewall for optimal performance and to prevent punctures.
- Brakes: Inspect brake levers for proper function and ensure brake pads are not excessively worn. Adjust brake cable tension if the levers feel too loose or too tight. Replace worn brake pads promptly.
- Chain: Keep the chain clean and lightly lubricated with bicycle-specific chain lubricant. This ensures smooth pedaling and prevents rust and premature wear.
- Fasteners: Periodically check all nuts, bolts, and quick-release levers to ensure they are tight and secure. Loose components can affect safety and performance.
- Cleaning: Clean the bicycle with mild soap and water. Avoid using high-pressure washers directly on bearings or other sensitive components. Dry thoroughly after washing.
- Storage: Store the bicycle in a dry place, away from direct sunlight and extreme temperatures, to prevent rust and material degradation.
