Safety Information
Always prioritize safety when riding. Adhere to the following guidelines:
- Always wear a properly fitted helmet.
- Ensure all bolts and quick releases are securely tightened before each ride.

Setup and Assembly
Your Retrospec Koda Plus bike requires some assembly. Follow these steps carefully:
- Unpacking: Carefully remove all components from the packaging. Retain packaging for future transport or storage.
- Front Wheel Installation: Attach the front wheel to the fork, ensuring it is centered and the quick release or axle nuts are tightened securely.
- Handlebar Installation: Insert the handlebar stem into the fork steerer tube. Align the handlebars straight with the front wheel and tighten the stem bolt.
- Pedal Installation: Identify left (L) and right (R) pedals. The right pedal tightens clockwise, and the left pedal tightens counter-clockwise. Ensure they are fully threaded and tightened.
- Seat Post and Saddle Adjustment: Insert the seat post with the saddle into the frame. Adjust the seat height so the rider's feet can comfortably touch the ground while seated, allowing for proper leg extension during pedaling. Tighten the seat post quick release or bolt securely. The adjustable seat height ranges from 21.5" to 27.5".
- Brake Adjustment: The bike features V-brakes. Ensure both front and rear brakes are properly aligned and the brake levers are easily reachable for small hands. Adjust the reach of the brake levers as needed using the adjustment screws. Test brake functionality before riding.
- Accessory Installation: Attach the included safety bell to the handlebars. Install the kickstand.

Operating Instructions
Understanding how to properly operate your bike ensures a safe and enjoyable riding experience.
- Starting: The bike features an optimized 4.0 gain ratio for easy starts and smooth pedaling. Begin by pushing off with one foot and then placing both feet on the pedals.
- Pedaling: Maintain a steady pedaling rhythm. The ergonomic saddle is designed for comfort during rides.
- Braking: Use both front and rear V-brakes simultaneously for controlled stopping. Apply gentle pressure initially and increase as needed. Avoid sudden, hard braking, especially with the front brake only, as this can cause instability.
- Steering: Guide the bike by gently turning the handlebars. Practice in an open, safe area to develop steering control.
- Adjustable Components: The seat and handlebars are adjustable to accommodate your child's growth. Regularly check and adjust these components to ensure a comfortable and safe riding position.

Maintenance
Regular maintenance ensures the longevity and safe operation of your bicycle.
- Tire Pressure: Check tire pressure before each ride. Maintain the recommended PSI (pounds per square inch) indicated on the tire sidewall for optimal performance and puncture resistance.
- Brakes: Inspect brake pads for wear and replace them when necessary. Ensure brake cables are free of fraying and properly tensioned. Adjust brake levers for proper reach and engagement.
- Chain: Keep the chain clean and lubricated. Apply a bicycle-specific lubricant periodically, especially after riding in wet conditions.
- Bolts and Fasteners: Periodically check all bolts, nuts, and quick releases for tightness. Loose components can affect safety and performance.
- Cleaning: Clean the bike with mild soap and water. Avoid high-pressure washers, which can damage bearings and seals. Dry thoroughly after washing.
Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
