Experts recommend that children over one year of age wear a bike helmet when riding in a bike trailer or riding their own bike (children younger than one should not wear a helmet or ride in a trailer because their neck muscles aren't strong enough, according to the Bicycle Helmet Safety Institute). For children one year of age and older, experts recommend the Giro Me2 bike helmet. It comes in one size and fits heads ranging in size from 18.75 to 20.5 inches. This helmet performs very well in independent impact tests, and the adjustable fit system gets rave reviews from parents. A pinch-guard buckle is another plus. While the Giro Me2 earns high marks from experts and parents, it has only six vents, so ventilation can be a problem on hot days. For older children ages five and up, experts recommend the Bell Trigger (*Est. $35). This helmet also excels in crash tests and has 23 vents to keep your child's head cool.
The Giro Me2 is included in ConsumerReports.org's helmet review, which is two years old. Editors only test three toddler helmets, but each one is rated on impact absorption, ventilation and weight. There's also a good number of user reviews at Amazon.com and Buzzillions.com.

The Bicycle Helmet Safety Institute writes a brief overview for nearly every bike helmet on the market, including the Giro Me2. Editors like that the helmet provides good rear coverage without pushing a toddler's head forward in a bike trailer.
