2. Check that the seat is level.

3. Ensure the child wears a helmet and appropriate safety gear.

Step O: Final Inspection

1. Visually inspect the entire bicycle for any loose parts or improper assembly.

2. Ensure the seat is securely fastened and does not tilt.

3. Use the torque wrench to check the seat post bolt, ensuring it is tightened to a maximum of 8 Nm.

Step P: Prepare for First Ride

Gently tilt the bicycle to check for any rattling or loose parts.

Step Q: Check Rear Wheel Attachment

1. Ensure the rear wheel is properly seated in the dropouts.

Step S: Check Pedals

1. Ensure the pedals are securely attached to the crank arms.

2. Tighten the pedals using the appropriate tool (usually a pedal wrench or large hex key).

Step T: Inflate Tires

1. Inflate the tires to the recommended pressure: 35 P.S.I (240 KPa) (2.4 BAR).

2. Use a tire pump to achieve the correct pressure.

Maintenance and Safety

U: Seat Height Adjustment Check

Ensure the seat height allows the child to place their feet flat on the ground with a slight bend in their knees when the pedal is at its lowest point. Listen for any clunking or rattling noises that may indicate loose parts.

V: Steering Check

Ensure the handlebars turn smoothly without any resistance. Listen for any clunking or rattling noises that may indicate loose parts.
