The bicycle should not be too big or complicated. The bicycle should have a bell or horn. Approved helmets meet stringent safety standards. Helmets that specifically are called bicycle helmets are designed only for that sport.
Helmets come in many sizes and varieties, including many infant sizes.
The front edge of the helmet should be two finger widths above the eyebrows. Front and back straps of the helmet should form a V just below the ear. Front straps should be vertical and the rear straps should be flat. Since most bicycle crashes occur because the child breaks a traffic rule, it is important to teach your child the traffic and road rules. Look left, right, and left again to check for cars.
