4. Setup and Assembly
The SJOEF Dolly bike comes 95% pre-assembled, making the final setup quick and straightforward. Basic tools are included. A beginner can typically complete assembly in 5 to 10 minutes.
- Install Handlebars: Insert the handlebar stem into the fork tube. Ensure the handlebars are straight and aligned with the front wheel. Tighten the stem bolt securely using the provided tools.
- Attach Pedals: Identify the Left (L) and Right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Screw them firmly into the crank arms.
- Adjust Saddle Height: Insert the seat post with the saddle into the frame's seat tube. Adjust the height so your child can comfortably touch the ground with their toes while seated. Secure the quick-release lever or bolt.
- Install Training Wheels: Attach the training wheels to the rear axle. Ensure they are securely fastened and provide stable support. Adjust their height so they lightly touch the ground when the bike is upright.

5. Operating Instructions
Familiarize your child with the bike's controls in a safe, open space.
- Starting to Ride: With training wheels, your child can push off and pedal immediately. Encourage them to look forward, not down at their feet.
- Braking: Teach your child to use both the hand brake (front wheel) and the coaster brake (rear wheel). The hand brake lever is located on the handlebar. Practice gentle braking first.

- Steering: Guide your child to steer gently by turning the handlebars.
- Removing Training Wheels: Once your child gains confidence and balance, the training wheels can be easily removed. This transition should be done gradually and with continued supervision.
- Adjustments: Periodically check and adjust the saddle and handlebar height as your child grows to maintain a comfortable and safe riding position.
6. Maintenance
Regular maintenance ensures the bike remains safe and functional.
- Tire Pressure: Check tire pressure before each ride. Maintain the recommended PSI (pounds per square inch) indicated on the tire sidewall.
- Brake Check: Ensure both hand and coaster brakes are responsive and stop the bike effectively. Adjust brake cables if necessary.
- Chain Lubrication: Lubricate the chain periodically, especially after riding in wet conditions, to ensure smooth pedaling and prevent rust.
- Bolt Tightness: Regularly inspect and tighten all bolts and nuts, particularly on the wheels, handlebars, seat post, and pedals.
- Cleaning: Clean the bike with mild soap and water. Avoid high-pressure washing, which can damage bearings. Dry thoroughly after cleaning.
- Storage: Store the bike in a dry place, away from direct sunlight and extreme temperatures, to prevent rust and material degradation.
