What Makes a Bike Helmet Fit Properly?
Finding the best fit bike helmet is crucial for safety and comfort while riding.
- Size: The helmet should be the right size for your head circumference, which can be measured using a soft tape measure around the forehead just above the ears.
- Adjustment System: A good helmet should have an adjustable retention system, usually a dial or strap mechanism at the back, that allows you to customize the fit to ensure the helmet sits snugly on your head.
- Strap Placement: The straps should form a V shape just below your ears and should be adjustable so that the helmet doesn’t tilt forward or backward when you move your head.
- Padding: The interior padding should be comfortable and provide a snug fit without excessive pressure points; it should also be removable and washable for hygiene.
- Stability: The helmet should remain securely in place when you shake your head; it shouldn’t shift or slide around, which can be tested by gently moving your head side to side after the helmet is secured.
