On a sunny fall morning, children wearing helmets and backpacks gathered with their parents in Montclair, New Jersey, for a group bicycle ride to two local elementary schools.
Volunteers in orange safety vests made sure everyone assembled in a neighbourhood shopping area was ready before the riders set off on their five-mile (eight kilometre) “bike bus” route.
