The GIRO TREMOR CHILD (2026) — Universal 47–54 cm, Matte Endless Green is a children’s bicycle helmet designed for everyday cycling and light outdoor play. It fits head circumferences from 47 to 54 cm and combines an adjustable retention system with ventilation channels to deliver a balance of comfort, fit and basic impact protection suitable for urban rides, scooters and recreational cycling.

Advantages

Its shell and internal fit system provide stable retention during normal cycling activities, while ventilation openings help manage airflow and reduce heat buildup. The Matte Endless Green finish is low-gloss and neutral, resisting visible scratches and maintaining a consistent appearance through regular use.

Suitable for

• Scooter and kickboard use where head protection is required
• Recreational cycling and visits to parks or playgrounds

When it may not be suitable

This helmet is designed for children and for typical low- to moderate-speed cycling situations. It may not be appropriate for high-speed downhill mountain biking, BMX racing, or other activities that require specialized, high-impact certification or additional facial and head protection. Also, it is not a substitute for helmets certified for motorized vehicle use.

Key specifications

• Fit range: 47–54 cm head circumference
• Finish: Matte Endless Green
• Adjustment: Integrated retention system for size tuning
• Ventilation: Multiple airflow vents for comfort
• Intended user: Children (youth sizing)

How to use

Place the helmet on the child’s head so it sits level and low on the forehead, then tighten the rear adjustment until the helmet feels snug but comfortable. Fasten and adjust the chin strap so that two fingers fit between the strap and the chin; straps should form a V under each ear. Inspect the helmet before each use for cracks, deformation or damaged straps and replace it after any significant impact or according to manufacturer guidance.

What to consider before purchase

• Measure the child’s head circumference to confirm the 47–54 cm fit range is appropriate
• Consider activities the child will do to ensure the helmet’s protective level matches the use case
• Check local safety standards and certification requirements for children’s helmets in your region

Usage recommendations

For best protection, replace the helmet after a significant impact even if no damage is visible, and periodically check fit as a child grows. Clean the helmet with mild soap and water and avoid solvents that could degrade materials.
