Safety Information
Your child's safety is paramount. Always ensure the following safety guidelines are followed:
- Helmet Use: Always ensure your child wears a properly fitted helmet that meets CPSC safety standards when riding.
- Adult Supervision: Children should always be supervised by an adult while riding.
- Pre-Ride Check: Before each ride, check that all nuts and bolts are tight, tires are properly inflated, brakes are functioning correctly, and the seat is adjusted to the correct height.
- Riding Environment: Ride in safe, open areas away from traffic, obstacles, and steep inclines. Avoid riding at dusk or night.
- Training Wheels: While training wheels provide stability, they are not a substitute for learning balance. Ensure they are securely attached.
- Clothing: Ensure clothing is not loose and will not get caught in the wheels or chain.

The Huffy Disney and Marvel Kids' Bike features the EZ Build system for quick and easy assembly. Follow these steps carefully:
- Unpack Components: Carefully remove all parts from the packaging. Ensure all components listed in the packing list are present.
- Insert Handlebar: Insert the handlebar stem into the fork tube. Ensure it is aligned straight with the front wheel and tightened securely.
- Fold Down Pedals: Fold the pedals down until they click securely into place.

Operating Instructions
Learning to ride is an exciting process. Here are basic operating instructions:
- Starting: Help your child get on the bike. Ensure their feet can touch the ground. Encourage them to push off with their feet and begin pedaling.
- Pedaling: The bike is single-speed, making pedaling straightforward. Encourage a smooth, consistent pedaling motion.
- Braking: This bike is equipped with a rear coaster brake. To stop, your child simply needs to pedal backward. Practice this in a safe, open area until they are comfortable.
- Steering: Guide your child to steer by gently turning the handlebars in the desired direction.

Maintenance
Regular maintenance will ensure the bike remains safe and performs optimally:
- Tire Pressure: Check tire pressure regularly. The recommended PSI is usually indicated on the tire sidewall.
- Cleaning: Clean the bike with a damp cloth and mild soap. Avoid harsh chemicals. Dry thoroughly after cleaning.
- Chain Lubrication: Periodically apply a light bicycle chain lubricant to the chain to ensure smooth pedaling and prevent rust.
- Bolt Tightness: Regularly check and tighten all nuts, bolts, and fasteners, especially on the handlebars, seat, and wheels.
- Storage: Store the bike indoors or in a dry, covered area to protect it from the elements.
Troubleshooting
Here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tires are flat or soft. | Low air pressure or puncture. | Inflate tires to recommended PSI. Check for punctures and repair if necessary. |
| Pedals are stiff or noisy. | Lack of lubrication or debris in chain/pedal mechanism. | Clean and lubricate the chain. Check pedals for obstructions. |
| Bike wobbles or feels unstable. | Loose bolts, improperly installed training wheels, or incorrect seat/handlebar alignment. | Check and tighten all fasteners. Ensure training wheels are level and secure. Realign handlebars and seat. |
