Choosing and wearing a bicycle helmet

In short: A good bicycle helmet fits firmly, protects forehead and back of the head and carries a CE mark with the EN 1078 standard. Germany has no helmet obligation, but it is recommended.

In more detail: A helmet cushions the impact by its foam deforming. After a fall it loses that ability and must be replaced.

In detail

• Size: Measure head circumference with a tape. The helmet must not wobble when you shake your head.
• Fit: Wear it level, about two fingers above the eyebrows. The chin strap is snug, one finger still fits underneath.
• Y-straps: The straps should form a Y below the ears.
• Replacement: Straight away after a fall, otherwise after about five years because material ages.
• Visibility: Bright colours or reflectors increase visibility.
