3.1 Braking

This bike is equipped with coaster brakes. To engage the brake, pedal backward firmly. Practice braking in a safe, open area until the rider is comfortable and proficient.

3.2 Riding with Training Wheels

The included training wheels provide stability for beginner riders. Ensure they are properly installed and adjusted. As the rider gains confidence and balance, the training wheels can be adjusted higher or removed entirely.

3.3 Safety Guidelines

• Always wear a properly fitted helmet.
• Ride in safe areas away from traffic.
• Ensure shoelaces are tied and clothing will not get caught in moving parts.
• Check tire pressure and brake function before each ride.
• Adult supervision is recommended, especially for young riders.

4. Maintenance

Regular maintenance ensures the longevity and safe operation of your Dynacraft Sweetheart Bike.

4.1 Tire Care

• Check tire pressure regularly. Refer to the tire sidewall for recommended PSI.
• Inspect tires for wear, cuts, or punctures. Replace damaged tires promptly.

4.2 Chain Lubrication

Periodically apply bicycle chain lubricant to the chain to ensure smooth pedaling and prevent rust. Wipe off excess lubricant.

4.3 Brake Inspection

Regularly test the coaster brake for proper function. If the brake feels loose or ineffective, consult a bicycle mechanic.

4.4 General Cleaning

Clean the bike with mild soap and water. Avoid high-pressure washing, which can damage bearings. Dry thoroughly after cleaning.

4.5 Bolt and Nut Check

Periodically check all bolts and nuts for tightness, especially on the handlebars, seat, pedals, and wheels. Tighten any loose fasteners.

5. Troubleshooting

This section addresses common issues you might encounter with your Dynacraft Sweetheart Bike.

• Pedals are stiff or noisy: Ensure pedals are securely tightened. Apply a small amount of grease to pedal threads if noise persists.
• Bike pulls to one side: Check that the handlebars are aligned with the front wheel and securely tightened. Also, ensure training wheels (if used) are evenly adjusted.
• Brakes feel weak: For coaster brakes, ensure the rider is applying sufficient backward pressure. If the brake mechanism feels loose or damaged, professional inspection is recommended.
• Tires lose air quickly: Inspect tires for punctures or valve stem issues. Inflate to recommended PSI. If the problem persists, the inner tube may need replacement.
