Spongebob Squarepants has a line of bike helmets in blue, and pink. These work for kids and the display makes it easy to find. There is absolutely no excuse not to grab one when you buy bikes for tykes this year.
Plesae remember how the helmet should fit, and how it is made. Adjust it snugly under your child's chin, and show them how to put it on and take it off. If your child should ever take a spill, please replace it right away. The material protecting your child's brain case will be flattened inside the helmet and will only provide safety once.
Merry Christmas and safe healthy biking to you all.
