Children will learn the helmet habit best if they begin wearing helmets when they first start riding on tricycles or bicycles. Helmets are sized to fit most children over the age of 1 year. Toddlers should wear special toddler helmets because their neck muscles may not be strong enough to support the larger hard shell one. If your child's neck can not support a helmet, they are not ready to ride go bicycling even in a child carrier or trailer. Three types of helmets are available-Hard Shell, Thin Shell and No Shell.
All helmets have an energy absorbing liner at the core.
The harder the shell, the better the protection of absorbing impacts on sharp or rounded surfaces but, the harder the shell, the heavier the helmet will be. So, choose the safest type of helmet that your child's neck muscles can support. These mean the helmet meets or exceeds recommended safety standards. Your child's helmet should fit comfortably and snugly, but not too tightly. It should touch your child's head at the crown, sides, front and back.
