There's no obligation to wear a helmet. But is there any real reason not to? If you ride in city traffic, there's no excuse - not all situations are predictable and regardless of whose fault it is, it's usually cyclists who at the greatest danger in an accident. With the current range of light and stylish city and touring helmets, everyone can find a model to suit their taste and head shape. Modern adjustment systems allow you to easily tailor the fit. InMold construction means modern helmets are much lighter, yet still safe, and useful details like an integrated tail light on the helmet come in very handy.
