Important Considerations
When choosing a kids bike size, keep in mind:
Children grow quickly - consider allowing some room for growth, but not too much that the bike becomes unsafe
Ensure your child can comfortably reach the ground with both feet while seated
Consider your child's confidence and skill level when choosing between sizes
Test the bike's weight - ensure your child can handle it comfortably
Safety Note
Always ensure proper safety equipment is used, including a correctly fitted helmet. Regular bike maintenance and size checks are essential as children grow. If in doubt about the right size, visit a local bike shop for professional fitting assistance.
