As more and more people get back on the bike for exercise or fresh air, falls and injuries are on the rise. So how old is your bike helmet and is it time to replace it? Consumer Reports offers recommendations.

Before you start pedaling, it’s important to have a helmet that will protect you in a fall or crash. Consumer Reports put several helmets through rigorous testing to see how well they absorb impact at about 14 mph, simulating how a biker might fall in an accident. The best bike helmet for adults is the Giro Register MIPS, which costs about $60, Consumer Reports said. “It’s a plastic layer inside the helmet that helps prevent transmitting rotational energy to the head if you get into a crash,” said Peter Anzalone of Consumer Reports. “That’s supposed to help against getting concussions.”For adults who prefer a commuter style, Consumer Reports recommends the LEM Boulevard, and for children, the Bontrager Tyro that costs about $50.
