Bell Boomerang

Reviewers say the Bell Boomerang is the best bike helmet for toddlers. It gets the highest score in one independent crash test for its superior head protection, and the stretchy interior helps ensure a snug fit. Even though it's a bit expensive for a toddler bike helmet, both experts and parents have good feedback on the Bell Boomerang. There are only eight vents, so this helmet only receives fair ratings for ventilation. In addition, the rear of the helmet protrudes slightly, which prevents children from leaning their head back in a stroller or bike trailer. Some parents posting to online review sites say this annoys their children. The Bell Boomerang fits head sizes between 18.5 inches and 20.5 inches in circumference; if your toddler has a very small head, check out the Specialized Small Fry (*Est. $40). This helmet accommodates heads as small as 17.25 inches in its toddler version.

The best comparative review of the Bell Boomerang comes from ConsumerReports.org. In their detailed test, they evaluate the helmet on impact absorption, fit, ventilation and ease of use. The Bicycle Helmet Safety Institute also provides a brief overview of the Bell Boomerang toddler helmet. There are not very many owner-written reviews available, but a few parents leave feedback at Amazon.com.
