Adjusting saddle height

The correct saddle height is crucial for pedaling efficiency and comfort. When your child first begins to ride, they may be more comfortable with a lower saddle height so they can put a foot down easily. As your child becomes more experienced, aim for only a slight bend in the knee when your child's foot is on the pedal in the 6 o'clock position as shown below.

If you raise the seatpost, ensure that the seatpost is inserted past the minimum insertion line.

Set the Tire Pressure

The tires must be inflated to 20-30 PSI. Periodically check and re-inflate the tires as needed.
