Best Bike Helmets of 2024

In Consumer Reports’ tests, we strap helmets onto “head forms” that simulate the size of a human head, then drop them 14 mph onto a flat anvil to find out how well they withstand impact. An electronic sensor inside the head form monitors the force that would be transmitted to a rider’s skull in an accident.

To ensure the helmet will stay in place during an accident, we test the strength of the chinstraps, attachment points, and buckles by dropping a weight that’s 8¾ pounds and 2 feet so that it yanks on the straps to simulate the force of a crash.

Our testers also evaluate each helmet for ventilation, fit adjustments, ease of use, and other features.
