Kids bike seats are available in many shapes, sizes and styles and are designed to suit every kid's comfort needs. The first thing to consider when buying a kids bike seat is what size is most appropriate for your child? Kids' bikes are generally sized differently than standard adult bikes (in terms of frame size rather than pedal size). Even when comparing a standard bike to a kid's bike, the seat base height and standover heights among different brands can differ significantly. In general, a bike may be advertised as being for a "5-year-old" or a "10-year-old", while a child may be a little over a year old and still be able to comfortably stand on a regular bike seat.
