Critical Mass is a monthly bike ride that happens on the last Friday of each month in most major cities of the world. It's a celebration of bicycles and a way of increasing awareness of bicycles among the motoring public. The event is free, no registration required and no requirements. Just show up and ride. The more the merrier. For one evening per month, bicycles ride major streets in metro areas in a large group, for visibility and safety. Recommendation: have lights front and back on your bike and wear your helmet. The ride is slow and the event is family friendly. Bring your kids, your parents and your cousin Jim. Let's have a fun and safe ride to celebrate bikes as a mode of transportation for a healthier community.
