Riding a bicycle can be a fun way to spend time outside. It is important to stay safe while riding your bike, so you should always wear a helmet. Helmets can protect your head from injury if you fall off your bike. The helmet should be tight enough so that it does not fall off your head. Many kids get hurt each year in bicycle accidents. Remember to put on your helmet every time you ride your bike, even if it is just a short ride.
