- Handlebar Installation: Insert the handlebar stem into the fork tube. Ensure the handlebars are straight and aligned with the front wheel. Tighten the stem bolt securely.
- Seat Post Installation: Insert the seat post into the frame. Adjust the seat height so the rider's feet can comfortably touch the ground when seated. Secure the quick-release lever or seat post bolt.
- Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Thread them carefully into the crank arms and tighten firmly with a wrench.
- Training Wheel Attachment: If desired, attach the included training wheels to the rear axle. Ensure they are securely fastened and provide stable support.
- Brake Adjustment: Check that both the hand brake and coaster brake (pedaling backward) are functioning correctly. Adjust cable tension for the hand brake if necessary to ensure responsive braking.

- Seat Post Installation: Insert the seat post into the frame. Adjust the seat height so the rider's feet can comfortably touch the ground with a slight bend in the knees. Secure the quick-release lever or seat post bolt.
Operating Instructions

Image Description: A detailed view of the Retrospec Koda Plus bike's braking system. It shows the easy-reach V-brake lever on the handlebar and explains the coaster brake mechanism activated by pedaling backward. This illustrates the two ways to brake.
- Riding Position: Ensure the seat height allows the child to comfortably reach the pedals and touch the ground with their toes. Handlebars should be at a comfortable height for steering.
- Braking: The Koda Plus features both a hand brake (V-brake) and a coaster brake.
- Hand Brake: Squeeze the lever on the handlebar gently to engage the front brake. Teach the child to apply both brakes smoothly and gradually.
- Coaster Brake: Pedal backward to engage the rear brake. This is an intuitive braking method for young riders.
- Using Training Wheels: Training wheels provide stability for beginners. As the child gains confidence and balance, they can be removed.
- Adjusting for Growth: The seat and handlebars are adjustable to accommodate your child's growth. Regularly check and adjust for optimal fit.

- Learning Balance: The Cub 2 is designed to teach balance. Encourage the child to walk, then glide with their feet off the ground.
- Riding Position: The seat height should allow the child to place both feet flat on the ground with knees slightly bent. This enables them to push off and stop easily.
- Steering: Teach the child to steer by looking where they want to go and gently turning the handlebars.
- Stopping: Children stop by placing their feet on the ground.
- Adjusting for Growth: Both the seat and handlebars can be adjusted to ensure a comfortable and effective riding position as your child grows.
Maintenance
Regular maintenance ensures the longevity and safe operation of your Retrospec bikes.
- Tire Pressure (Koda Plus): Check tire pressure before each ride. Maintain pressure within the range indicated on the tire sidewall. (Note: Cub 2 has flat-free tires).
- Brake Check (Koda Plus): Regularly inspect brake levers, cables, and pads for wear. Ensure brakes engage smoothly and effectively.
- Chain Lubrication (Koda Plus): Lubricate the chain periodically with bicycle-specific chain lubricant to ensure smooth pedaling and prevent rust.
- Bolt and Nut Tightness: Periodically check all bolts and nuts, especially on the handlebars, seat post, wheels, and pedals, to ensure they are securely tightened.
- Cleaning: Clean the bikes with a damp cloth and mild soap. Avoid high-pressure washing, which can damage bearings. Dry thoroughly after cleaning.
- Storage: Store bikes in a dry, covered area to prevent rust and damage from weather exposure.
Troubleshooting
