to my kids there is a simple rule:
NO HELMET... NO BIKE!
I have heard parents say to their kids... if you are going to ride fast you need your helmet
but honestly...
where is the cut off
I ride my bike all the time
for pleasure... for sport... to get to and from work... and then also the leisurely trip to the corner store
riding without a helmet is not a consideration
wear a helmet on the bike is like wearing pants when I head out the door
