Since there’s no telling what height or how physically coordinated and well-developed a child may be at any given age, age is not a reliable, objective criterion for sizing a bike.Inseam and height measurements can be obtained easily, quickly, and practically simultaneously with no more than a ruler, a pencil and a tape measure.The other crucial measurement for providing your child with the best bike fit is overall height, a solid indicator of the necessary wheel size for a kids’ bike.Correlating the inseam to the bike’s stand-over height provides the child with maximum control and comfort. The most essential measurement for calculating the perfect bike size is your child’s inseam.

Finding the best possible fit for your child’s bike provides the control and maneuverability a child needs to learn to ride well and safely, and to derive maximum enjoyment from their biking experience.

Plug two simple measurements into our easy-to-use charts below to give your child a head start toward safe and happy cycling with the right size bike. There is no more important factor in your purchasing decision for your child’s (grandchild’s, niece’s, etc.) bicycle than buying just the right size. Yet regardless of whether it’s their first or fifth bike, the quality of their riding experience is largely determined by how well the bike fits his or her particular body.

Few rites of passage loom larger in a child’s mind than riding their first bicycle.
