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.
